Hines Farm Setup also included removal of hand crank so a "Power Up & Down feature" could be implemented.

April 27, 2014, I converted my Harbor Freight Sawmill to "Power Up and Down". Remove hand crank by driving the retaining pin out. Replaced the crank with a 3/4" nut with threads drilled out and a .2" hole drilled through the perpendicular axis so the retaining pin can be driven through it and the screw drive shaft. To power the sawmill up and down I use an 18 Volt battery, reversible powered drill with a 3/4" socket attached. Works great and is a lot easier and quicker than hand cranking at a height above your shoulder. If you modify yours, follow safe procedures and do at your own risk.

Are We Becoming China's Factory Farm? | Mother Jones

US hog operations are feeding more than a billion people's growing appetite for pork.
—By Tom Philpott

Illustration: Michael Klein

China is in the midst of a love affair with pork. Its consumption of the stuff has nearly doubled since 1993 and just keeps rising. The Chinese currently eat 88 pounds per capita each year—far more than Americans' relatively measly 60 pounds. To meet the growing demand, China's hog farms have grown and multiplied, and more than half of the globe's pigs are now raised there. But even so, its production can't keep up with the pork craze.

So where is China looking to supply its demand for chops, ribs, loins, butts, and bellies? Not Southeast Asia or Africa—more like Iowa and North Carolina. US pork exports to China surged from about 57,000 metric tons in 2003 to more than 430,000 metric tons in 2012, about a fifth of all such exports. And that was before a Chinese company announced its intention to buy US pork giant Smithfield Foods in 2013. The way things are going, the United States is poised to become China's very own factory hog farm. Here are a few reasons why:

- It's now cheaper to produce pork in the US than in China. You read that right: Our meat industry churns out hogs for about $0.57 per pound, according to the US Department of Agriculture, versus $0.68 per pound in China's new, factory-scale hog farms. The main difference is feed costs. US pig producers spend about 25 percent less on feed than their Chinese counterparts, the USDA found, because the "United States has more abundant land, water, and grain resources."

- Americans are not as fond of "the other white meat" as we once were. You wouldn't know it from the menus in trendy restaurants, but US consumers' appetite for pork hit a peak in 1999 and has declined ever since. Yet industry, beholden to shareholders demanding growth, keeps churning out more. According to its latest projections, the USDA expects US pork exports to rise by another 0.9 metric tons by 2022—a 33 percent jump from 2012 levels.

- Much of China's arable land is polluted. Fully 40 percent has been degraded by erosion, salinization, or acidification—and nearly 20 percent is tainted by industrial effluent, sewage, excessive farm chemicals, or mining runoff. The pollution makes soil less productive, and dangerous elements like cadmium have turned up in rice crops.

- Chinese rivers have been vanishing since the 1990s as demand from farms and factories has helped suck them dry. Of the ones that remain, 75 percent are severely polluted, and more than a third of those are so toxic they can't be used to irrigate farms, according to a 2008 report by the Chinese government. According to the World Bank, China's average annual water resources are less than 2,200 cubic meters per capita. The United States, by contrast, boasts almost 9,400 cubic meters of water per person.

- Chinese consumers are losing trust in the nation's food supply—and will pay for alternatives. A spate of food-related scandals over the past half decade has made food safety the Chinese public's No. 1 concern, a 2013 study from Shanghai Jiao Tong University found. Judith Shapiro, author of the 2012 book China's Environmental Challenges and director of the Natural Resources and Sustainable Development program at American University, says she expects Smithfield pork to command "quite a premium" in China, because it's perceived as safer and better than the domestic stuff. Already, "US pork is particularly popular and commands premium prices, as it is viewed as higher quality due to our strict food safety laws," a Bloomberg Businessweek columnist reported last July.

But what's good for pork exporters may not be good for the United States: More mass-produced pork also means more pollution to air and water from toxic manure, more dangerous and low-wage work, and more antibiotic-resistant pathogens. And that's just the beginning. In addition to ramping up foreign meat purchases, China is also rapidly transforming its domestic meat industry along the US industrial model—and importing enormous amounts of feed to do so. The Chinese and their hogs, chickens, and cows gobble up a jaw-dropping 60 percent of the global trade in soybeans, and the government may soon also ramp up corn imports—because while Beijing currently limits foreign corn purchases, meat producers are clamoring for more. And where does a third of the globe's corn come from? You guessed it: The good old USA.

The transformation of timberland ownership and markets in North America | Forest Business Network

It’s not every day I get to hear one of America’s top forest industry CEOs speak on the global state of our industry. Mike Covey, CEO of Potlatch Corporation, recently spent the day in Missoula meeting with University of Montana College of Forestry and business students, faculty, and community members, then concluded his day with an hour-long lecture to over 200 folks on “The Transformation of Timberland Ownership and Markets in North America.”

In his presentation, Mike addresses why timber companies are becoming real estate investment trusts and how a global economy affects the U.S. lumber, timber, and log markets. While the U.S. will probably build some 5-7 million homes over the next five years, China has mandated close to 35 million. Where will they get their building products? A lot of it will come from North America. (By the way, companies looking to diversify their markets through exports will certainly benefit from presentations at the SmallWood Conferencethis June.)

The University of Montana’s video staff did a great job of filming Mike’s speech and I think you will enjoy watching his one-hour presentation and Q&A from the audience.

A Primal Diet for Modern Times, part 2 - YouTube





Published on Mar 17, 2014



Is our ancestors' hunter-gatherer diet the best for optimal health and longevity, in our stress- and pollution-filled world? Not entirely, says Nora Gedgaudas, author of Primal Body, Primal Mind. She advocates a ketogenic diet, where fats are the primary fuel source rather than carbohydrates — moderate protein (from grass-fed or wild caught animals), very low starch and natural sugars, plentiful fibrous green vegetables, generous natural fats, and no vegetable oils. "Once [our ancestors] adopted ketones as a primary source of fuel, our cerebral blood flow and oxygenation increased by over 39% in normal human brains." Returning to a ketogenic diet improves brain function and can help treat or even prevent diabetes and Alzheimers

Joel Salatin responds to New York Times’ ‘Myth of Sustainable Meat’ | Grist

By Joel Salatin
The following post originally appeared on the Polyface Farms Facebook page.

Cows at Polyface Farm. Photo by Amber Karnes.

The recent editorial by James McWilliams, titled “The Myth of Sustainable Meat,” contains enough factual errors and skewed assumptions to fill a book, and normally I would dismiss this out of hand as too much nonsense to merit a response. But since it specifically mentionedPolyface, a rebuttal is appropriate. For a more comprehensive rebuttal, read the book Folks, This Ain’t Normal.

Let’s go point by point. First, that grass-grazing cows emit more methane than grain-fed ones. This is factually false. Actually, the amount of methane emitted by fermentation is the same whether it occurs in the cow or outside. Whether the feed is eaten by an herbivore or left to rot on its own, the methane generated is identical. Wetlands emit some 95 percent of all methane in the world; herbivores are insignificant enough to not even merit consideration. Anyone who really wants to stop methane needs to start draining wetlands. Quick, or we’ll all perish. I assume he’s figuring that since it takes longer to grow a beef on grass than on grain, the difference in time adds days to the emissions. But grain production carries a host of maladies far worse than methane. This is simply cherry-picking one negative out of many positives to smear the foundation of how soil builds: herbivore pruning, perennial disturbance-rest cycles, solar-grown biomass, and decomposition. This is like demonizing marriage because a good one will include some arguments.

As for his notion that it takes too much land to grass-finish, his figures of 10 acres per animal are assuming the current normal mismanagement of pastures. At Polyface, we call it neanderthal management, because most livestock farmers have not yet joined the 20th century with electric fencing, ponds, piped water, and modern scientific aerobic composting (only as old as chemical fertilization). Hence, while his figures comparing the relative production of grain to grass may sound compelling, they are like comparing the learning opportunities under a terrible teacher versus a magnificent teacher. Many farmers, in many different climates, are now using space-age technology, biomimicry, and close management to get exponential increases in forage production. The rainforest, by the way, is not being cut to graze cattle. It’s being cut to grow transgenic corn and soybeans. North America had twice as many herbivores 500 years ago than it does today due to the pulsing of the predator-prey-pruning cycle on perennial prairie polycultures. And that was without any corn or soybeans at all.

Apparently if you lie often and big enough, some people will believe it: Pastured chicken has a 20 percent greater impact on global warming? Says who? The truth is that those industrial chicken houses are not stand-alone structures. They require square miles of grain to be carted into them, and square miles of land to handle the manure. Of course, many times that land is not enough. To industrial farmers’ relief, more often than not a hurricane comes along just in time to flush the toilet, kill the fish, and send pathogens into the ocean. That’s a nice way to reduce the alleged footprint, but it’s devilish sleight of hand with the data to assume that ecological toxicity compensates for the true land base needed to sustain a factory farm.

While it’s true that at Polyface our omnivores (poultry and pigs) do eat local GMO (genetically modified organism)-free grain in addition to the forage, the land base required to feed and metabolize the manure is no different than that needed to sustain the same animals in a confinement setting. Even if they ate zero pasturage, the land is the same. The only difference is our animals get sunshine, exercise, fresh pasture salad bars, fresh air, and a respectful life. Chickens walking on pasture certainly do not have any more leg sprains than those walking in a confinement facility. To suggest otherwise, as McWilliams does, is sheer nonsense. Walking is walking — and it’s generally considered to be a healthy practice, unless you’re a tyrant.

Interestingly, in a lone concession to compassion, McWilliams decries ranging hogs with rings in their noses to keep them from rooting, lamenting that this is “one of their most basic instincts.” Notice that he does not reconcile this moral imperative with his love affair with confinement hog factories. Nothing much to use their noses for in there. For the record, Polyface never rings hog noses, and in the few cases where we’ve purchased hogs with rings, we take them out. We want them to fully express their pigness. By moving them frequently using modern electric fencing, polyethylene water piping, high-tech float valves, and scientifically designed feed dispensers, we do not create nor suffer the problems encountered by earlier large-scale outdoor hog operations 100 years ago. McWilliams has apparently never had the privilege of visiting a first-rate, modern, highly managed, pastured hog operation. He thinks we’re all stuck in the early 1900s, and that’s a shame because he’d discover the answers to his concerns are already here. I wonder where his paycheck comes from?

Then McWilliams moves on to the argument that economic realities would kick in if pastured livestock became normal, driving farmers to scale up and end up right where we are today. What a clever ploy: justify the horrible by eliminating the alternatives. At Polyface, we certainly do not discourage scaling up — we actually encourage it. We think more pasture-based farms should scale up. Between the current abysmal state of mismanagement, however, and efficient operations, is an astronomical opportunity to enjoy economic and ecological advantages. McWilliams is basing his data and assumptions on the poorest, the average or below. If you want to demonize something, always pick the lowest performers. But if you compare the best the industry has to offer with the best the pasture-based systems have to offer, the factory farms don’t have a prayer. Using portable infrastructure, tight management, and techno-glitzy tools, farmers running pastured hog operations practically eliminate capitalization costs and vet bills.

Finally, McWilliams moves to the knock-out punch in his discussion of nutrient cycling, charging specifically that Polyface is a charade because it depends on grain from industrial farms to maintain soil fertility. First of all, at Polyface we do not assume that all nutrient movement is anti-environmental. In fact, one of the biggest reasons for animals in nature is to move nutrients uphill, against the natural gravitational flow from high ground to low ground. This is why low lands and valleys are fertile and the uplands are less so. Animals are the only mechanism nature has to defy this natural downward flow. Fortunately, predators make the prey animals want to lounge on high ground (where they can see their enemies), which insures that manure will concentrate on high lookout spots rather than in the valleys. Perhaps this is why no ecosystem exists that is devoid of animals. The fact is that nutrient movement is inherently nature-healing.

But, it doesn’t move very far. And herein lies the difference between grain used at Polyface and that used by the industry: We care where ours comes from. It’s not just a commodity. It has an origin and an ending, start to finish, farmer to eater. The closer we can connect the carbon cycles, the more environmentally normal we will become.

Second, herbivores are the exception to the entire negative nutrient flow argument because by pruning back the forage to restart the rapid biomass accumulation photosynthetic engine, the net carbon flow compensates for anything lost through harvest. Herbivores do not require tillage or annuals, and that is why all historically deep soils have been created by them, not by omnivores. It’s fascinating that McWilliams wants to demonize pasture-based livestock for not closing all the nutrient loops, but has no problem, apparently, with the horrendous nutrient toxicity like dead zones in the Gulf of Mexico the size of New Jersey created by chemical fertilizer runoff to grow grain so that the life of a beef could be shortened. Unbelievable. In addition, this is one reason Polyface continues to fight for relaxing food safety regulations to allow on-farm slaughtering, precisely so we can indeed keep all these nutrients on the farm and not send them the rendering plants. If the greenies who don’t want historically normal farm activities like slaughter to occur on rural acreage could understand how devastating these government regulations actually are to the environmental economy, perhaps McWilliams wouldn’t have this bullet in his arsenal. And yes, human waste should be put back on the land as well, to help close the loop.

Third, at Polyface, we struggle upstream. Historically, omnivores were salvage operations. Hogs ate spoiled milk, whey, acorns, chestnuts, spoiled fruit, and a host of other farmstead products. Ditto for chickens, who dined on kitchen scraps and garden refuse. That today 50 percent of all the human edible food produced in the world goes into landfills or greenie-endorsed composting operations rather than through omnivores is both ecologically and morally reprehensible. At Polyface, we’ve tried for many, many years to get kitchen scraps back from restaurants to feed our poultry, but the logistics are a nightmare. The fact is that in America we have created a segregated food and farming system. In the perfect world, Polyface would not sell eggs. Instead, every kitchen, both domestic and commercial, would have enough chickens proximate to handle all the scraps. This would eliminate the entire egg industry and current heavy grain feeding paradigm. At Polyface, we only purport to be doing the best we can do as we struggle through a deviant, historically abnormal food and farming system. We didn’t create what is and we may not solve it perfectly. But we’re sure a lot farther toward real solutions than McWilliams can imagine. And if society would move where we want to go, and the government regulators would let us move where we need to go, and the industry would not try to criminalize us as we try to go there, we’ll all be a whole lot better off and the earthworms will dance.

Joel Salatin is the owner of Polyface Farm -- which was featured in Michael Pollan's book The Omnivore's Dilemma and the documentary film Food, Inc. He is a third generation family farmer working his land in Virginia's Shenandoah Valley with his wife, Teresa, son Daniel, daughter Rachel, and their families. Polyface Farm, an organic grass-fed farm, services more than 3,000 families, 10 retail outlets and 50 restaurants through on-farm sales and metropolitan buying clubs. Salatin writes extensively in magazines such as Stockman Grass Farmer, Acres USA, and American Agriculture.

TOLIET PAPER - Simple Garden Tip: Best Seed Tape Ever: Organic Gardening

Best Seed Tape Ever
Planting tiny seeds is easy with this simple gardening trick.
It’s difficult to space tiny seeds, such as carrots, in the garden. The best way to solve this problem is to make homemade seed tape. Here’s how to do it:

1. Unroll a strip of toilet paper on a table (double ply works best), mist it with a sprayer, and place the seeds along the center of the strip. Be sure to space the seeds based on the seed packet’s recommendation. Tip: Alternate carrot seeds with radish seeds because when the radishes sprout, they help to mark the row and break the ground.

2. Starting along the strip’s long edge, fold a third of the paper over the seeds, then fold the other third over to cover the seeds completely. Lightly tamp the paper, misting it again to secure the seeds. Make as many of these strips as you need. Then carefully carry them to the garden.

3. Make shallow furrows in the prepared soil, lay the strips down, and cover them. In a jiffy, your small seeds will be planted and perfectly spaced.

A Primal Diet for Modern Times, part 1 - YouTube



https://www.youtube.com/watch?v=0-eaPlmzz94

Published on Mar 10, 2014
Nora Gedgaudas used to believe a plant-based diet was the healthiest. That belief got turned upside down when she spent a summer studying wolves near the North pole. "We are fundamentally ice-age hunter-gatherers," states the nutritionist and author of Primal Body, Primal Mind. She points out that our genes are 99.9% the same as our ancestors - they haven't yet adapted to the relatively recent agriculturally-based lifestyle based on grains. As a result, our bodies have no need for dietary carbohydrates. By contrast, "Fat, to us means survival.... Dietary fat is the most nutrient-dense thing we can consume, rich in fat-soluble nutrients, and essential for the functioning of our brain and nervous systems." Episode 260.

UltraBattery a Boon to Renewable Energy, Grid Storage, and EVs > ENGINEERING.com

Tom Lombardo  March 09, 2014

UltraBattery® with its Inventor, Dr. Lan Lam (Image courtesy of CSIRO)

Batteries pack a lot of energy into a small space, but they’re slow to charge, they lose their capacity after several charge-discharge cycles, and many are not environmentally friendly. Supercapacitors (also known as ultracapacitors) can be charged very quickly, can survive a near limitless number of charge-discharge cycles, and are made from relatively benign materials.

Electric and hybrid vehicles (EVs and HEVs) need the benefits of both technologies, and often employ a blend of batteries and supercaps, with the former providing a long driving range and the latter storing energy from regenerative braking and giving quick bursts of energy for rapid acceleration.

Grid-level storage combined with renewable energy has the potential to replace gas fired “peaker plants,” but like the EV, it requires the high energy density of batteries and the quick response time and long life of supercaps.

Using batteries and supercaps together requires control circuitry to move electricity to and from the different storage elements. But what happens if you combine the battery and the supercap in one package? You get the best of both worlds: the UltraBattery®, developed by a team from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and now produced by CSIRO spinoff company Ecoult. The UltraBattery is a lead-acid battery with a built in supercapacitor, as shown here:


Image courtesy of Ecoult

Conventional lead-acid batteries suffer from sulfation, lead sulfate crystals growing on the battery’s plates, causing a decrease in capacity and an increase in internal resistance. Sulfation occurs naturally with age, but it’s made worse by operating the battery at intermediate states of charge (somewhere between full and empty). Since that’s the normal condition for EV batteries and grid-level storage systems, you can see why many of those applications employ more costly NiMH or Li-ion batteries instead of inexpensive lead-acid batteries. According to CSIRO and Ecoult engineers, using a carbon-based supercap in parallel with the battery reduces negative plate sulfation. They don’t explain the chemistry behind that and I’m not a chemist, but independent testing by Sandia National Labs confirmed that the UltraBattery showed very little sulfation compared to standard deep-cycle lead-acid batteries under the same conditions.

Additional tests by Sandia National Labs showed that when subjected to cycles that are typical of grid-level storage applications, the UltraBattery lasted ten times longer than a conventional lead-acid battery. When tested under hybrid EV conditions, the UltraBattery once again outperformed its lead-acid counterpart by a factor of ten, performing at least as well as NiMH batteries but at a significantly lower cost.

UltraBatteries achieved a round-trip efficiency of around 90%, compared to 70% for conventional lead-acid batteries. This occurred under both low-current and high-current charge-discharge cycles. (For more details on the exact testing procedures and results, click the “Read More…” link at the end of this article and download the white paper.)

In addition to its superior electrical characteristics, the UltraBattery is non-flammable and made from materials that are abundant, non-hazardous, and fully recyclable. The UltraBattery is safe, clean, efficient, reliable, and inexpensive. What more can you ask for?

Renewable energy sources like solar and wind are intermittent, sometimes providing more energy than needed while other times not generating enough. Cost effective, efficient grid-level storage is the key to a renewable energy future. Electric vehicles and hybrids demand high capacity, inexpensive, and lightweight batteries. Likewise, storage is the main obstacle standing in the way of universal adoption of EVs. While research into alternative battery chemistry continues, it could be that the good old lead-acid battery, enhanced by a built-in supercapacitor, will satisfy both needs.

Enhancing the Mississippi Watershed with Perennial Bioenergy Crops on Vimeo



Today, non-point source pollution is the greatest threat to the nation’s water and the main reason why our waters remain polluted. 

The vast majority of these nutrients come from corn and soybeans production in the upper Midwest. These nutrients not only contaminate drinking water wells and local surface waters, but are chiefly responsible for the Gulf’s hypoxic zone, the largest hypoxic region in the U.S. and the second largest in the world. 

This CenUSA video, Enhancing The Mississippi River Watershed with Perennial Bioenergy Crops, focuses on the role perennial grass energy crops can play in improving water qualtiy. Compared to row crops, perennial grasses have been shown to reduce runoff, erosion and nutrients by as much as 90%. The video discusses the role perennial grasses can plan in improving the Mississippi River Watershed and the Gulf of Mexico. 

It features interviews with and Gulf Hypoxia co-chairs Nancy Stoner (Acting Assistant Administrator for the Office of Water at EPA) and Bill Northey (Iowa Secretary of Agriculture) and CenUSA project director Ken Moore. It discusses land use modeling research being conducted by CenUSA co-project directors Cathy Kling (Iowa State University) and Jason Hill (University of Minnesota). 

The video also features farmer and bioenergy pioneer Jamie Derr and University of Minnesota scientist Bonnie Keeler.

A Discussion on Ecology Ethics with Joel Salatin -- MOTHER EARTH NEWS FAIR - YouTube



Bryan Welch, Publisher of Mother Earth News, sat down with Farmer/Philosopher Joel Salatin at the MOTHER EARTH NEWS Fair in Seven Springs, PA. Joel has written multiple books including Fields of Farmers, The Sheer Ecstasy of Being a Lunatic Farmer and Everything I Want to do is Illegal. He lives and works on his multi-generational farm, Polyface Farms, in Virginia's Shenandoah Valley, where he and his family raise pastured meats and organic crops.
In this conversation we learn why at the end of the day it's much more satisfying to do physical labor rather than to "blink your existence into cyberspace" and the many ways we can be good stewards of the land.

More on Self-Sufficiency and Sustainable Living from MOTHER EARTH NEWS: Providing high-quality food for your family year-round takes foresight and planning, plus healthy doses of commitment and follow-through.

Iowa is getting sucked into scary, vanishing gullies | Grist

By Tom Philpot

See that gash in the land? Until heavy rains hit in May 2013, it was filled with topsoil. It’s an “ephemeral gully,” and Iowa is full of them after hard rains.

Last year, after a record drought in 2012, Iowa experienced the wettest spring in its recorded history. The rains triggered massive runoff from the state’s farms into its creeks, streams, and rivers, tainting water with toxic nitrate from fertilizer. Nitrate levels in the state’s waterways reached record levels — so high that they emerged as “a real issue for human health,” Bob Hirsch, a hydrologist for the U.S. Geological Survey, told the Associated Press.

The event illustrated two problems facing Iowa and the rest of the nation’s topsoil-rich grain belt. The first is the challenge of climate change: How to manage farmland in an era when weather lurches from brutal drought to flooding, as it likely will with increasing frequency. The second, related one is the largely invisible crisis of Iowa’s topsoil, which appears to be eroding at a much higher rate than U.S. Department of Agriculture numbers account for — and, more importantly, at 16 times the natural replacement rate.

I got that disturbing assessment from Richard Cruse, an agronomist and the director of Iowa State University’s Iowa Water Center. Cruse’s on-the-ground research documents a particular kind of soil erosion highly relevant to last year’s heavy rains. Cruse told me that with current methods, the USDA measures a kind of soil loss called sheet and rill erosion, wherein water washes soil away in small channels that farm at the soil surface during rains. Under that measure, Iowa farmland loses on average 5.1 tons of topsoil per acre every year, according to the USDA’s latest numbers, which are from 2007.

The USDA sees five tons per acre as a “magic number,” Cruse said, because it’s generally accepted to be the rate at which soil renews itself. So the prevailing view has been that “if we can limit erosion to five tons per acre, we can do this forever,” Cruse said. But he added that the “best science” (explained here) indicates that the real sustainable erosion rate is closer a half ton per acre — meaning that even by the USDA’s own limited measure, Iowa’s soils are eroding much faster than they can be replaced naturally.

But here’s where we get to the scary part. Using stereo-photographic techniques, Cruse and his team have been measuring a different from of erosion through what are known as “ephemeral gullies” — that is, large gashes in farm fields formed by water during heavy rains, bearing soil rapidly away and dispersing it into streams and rivers. This kind of erosion is not included in conventional soil-loss measures, and as a result, the USDA is “way underestimating” erosion in Iowa, he said.

Cruse’s team has have not collected data long enough, nor analyzed it thoroughly enough, to say exactly how much soil is being surrendered in this way. But he added that he “could say with a lot of confidence” that ephemeral gullies are claiming on average an additional 2.5 to three tons per acre — bringing the grand total as high as eight tons per acre, 60 percent higher than the USDA’s sustainable threshold of five tons and 16 times higher than the 0.5-ton limit that Cruse says is more scientifically valid.

Ephemeral gullies represent not only an alarming disappearance of productive soil; they also mean a concentrated transfer of farm chemicals into waterways, where they feed algae blooms and get into municipal drinking water. That’s because when an ephemeral gully appears one growing season, farmers use a plow implement called a disk to push fresh topsoil into the gullies. That topsoil, heavily treated with fertilizer and herbicides, is just the kind that causes the most water-quality damage when the next ephemeral gully forms, Cruse said. It’s a startling image: The gullies are essentially pipelines, periodically filled by farmers, that move prime soil from fields into streams.

And there’s a feedback loop operating here, Cruse said — as Iowa’s farmland loses soil, it also loses the ability to trap water, because soil acts as a sponge. That makes it more prone to flooding, and more likely to sprout ephemeral gullies.

A tale of two fields: On one side of the road, a gully cuts through an unprotected field (bottom photo). On the other side (top) a grass waterway stops the gully, but is filled with rocks and mud from the other side.

In the wake of last year’s heavy rains, Environmental Working Group filed a great report called “Washout” on the damage done to Iowa’s soils, building on its landmark 2011 study on Iowa’s erosion problem, “Losing Ground.” EWG looked at data from ISU’s Iowa Daily Erosion Project, and found that that in less than a week, farmland in 50 townships covering 1.2 million acres suffered average erosion of more than five tons per acre — and that in 15 of those townships fields suffered average erosion of 7.5 to 13 tons per acre. (The recognized, and probably overstated, “sustainable” rate of erosion, recall, is five tons per year.)

And here’s the catch: The Iowa Daily Erosion Project doesn’t have the technology to account for ephemeral gullies. In the wake of the May storms, the EWG researchers “drove a random loop” through seven counties around EWG’s Midwest office in Ames. They found “gullies scarring field after field,” as well as roadside ditches “full of mud and polluted runoff — a very bad sign for Iowa’s already polluted streams.” (If you don’t believe that “field after field” had formed gullies, check out the EWG researchers’ slideshow from their trip, which I’ve plunked down below.) So, erosion from last year’s rains was “actually worse — likely far worse — than even the IDEP estimates,” EWG concludes.

I asked Cruse, whose team is creating tools that can help document gully erosion, what farming practices could stem the hemorrhaging of Iowa’s soils. He pointed to winter season cover crops, which have the twin virtues of (a) building organic matter in soil, giving it more capacity to sponge up water; and (b) providing a cover, a mat of plant matter that shields soil from being disturbed and dislodged by heavy rains. Both help keep soil in place and prevent gullies. (For a deep dive into cover crops, see my 2013 piece on the innovative Ohio farmer David Brandt.)

Cruse also mentioned reintegrating grazing animals into Iowa’s fields. Maintaining pastures for livestock means an abundance of perennial grasses, which act like cover crops and keep soil in place — granted, of course, that the animals are properly rotated and not allowed to overgraze, which also degrades soil.

I also asked him how long Iowa’s farmers could go on pushing their soils for maximum corn and soy production without integrating cover crops and livestock on a much larger scale than is happening now. He said that Iowa’s status as an agriculture powerhouse relative to other farming regions worldwide will likely continue for a while, because most of the globe’s farmland is experiencing equal or even greater soil degradation. Not the most comforting answer!

He added he he can’t pinpoint the year “when we cross a ‘game over’ condition.” But he could say with certainty that the “impact of soil erosion is a gradual decline in production potential and, probably even more important, soil resilience—the capacity of soil to supply needed water and nutrients under weather- or climate-stressful conditions.”

After talking to Cruse and reading the EWG report, I reread the first chapter of University of Washington ecologist David Montgomery’s terrific 2007 book Dirt: The Erosion of Civilizations. ”With just a couple feet of soil standing between prosperity and desolation, civilizations that plow through their soil vanish,” Montgomery wrote.

Tired of corn, corn, corn or cane, cane, cane? There are 101 feedstocks in the biofuels canon.

Here’s what’s up with each of them, and all of them.

In Florida, Biofuels Digest released its annual Guide to biofuels feedstocks, tracking 10,658 items published in the Digest in the past 48 months on 101 feedstocks for biofuels, biopower, renewable chemicals and biobased materials.

In total, there were 3345 items on established grains & grasses, 1204 items on established oilseeds, 194 items on woods, 1399 items on novel feedstocks, 1824 items on aquatic species, and 2688 items on residues.

In all, the Digest is tracking 6 aquatic species, 8 established grains & grasses, 14 established oilseeds, 15 types of wood, 23 novel feedstocks, and 35 types of residues.

“Articles about a feedstock don’t always translate into acres and tonnes,” noted Digest editor Jim Lane. “A number of feedstocks are important, especially the woods, even if they receive less attention in the form of news. Plus, it’s important to keep in mind that almost every feedstock defined as “novel” has generally been around for some time; what is novel is generally that they are being investigated for use at industrial scale.”
Takeaways

Residues are king — even though popular feedstocks like corn, cane and soy attract the most attention as individual feedstocks. The very diversity of residues — agricultural, animal, forest, industrial, and municipal – tends to disperse interest against a wide backdrop of materials. At the same time, groupings like “algae” put hundreds of strains into one category. Accordingly, popularity sometimes is driven by the way the category os drawn.

Woods? An under-considered source for biofuels — primarily because fermentation systems struggle with woods, which generally (though not exclusively) lend themselves to thermocatalytic systems, which have generally received less attention over the years.

Black locust showing promise for biomass potential | ACES News :: College of ACES, University of Illinois


URBANA – Researchers from the Energy Biosciences Institute at the University of Illinois, evaluating the biomass potential of woody crops, are taking a closer look at the black locust (Robinia pseudoacacia), which showed a higher yield and a faster harvest time than other woody plant species that they evaluated, said U of I associate professor of crop sciences Gary Kling.

“For now the only thing you can do with it is use it for direct combustion,” Kling said. “But if it becomes a major crop other researchers could start working on the process of how to break it down,” he said. “The EBI is working on how to get the sugars out of plants and how to turn those to alcohols. It is a very tough thing to do. It’s typically been tough to break down the biomass in woody plants to make it useful for alcohol production. Our plan is to be able to take anything we grow and convert it into a drop-in fuel.”

Kling said he and his team’s role in the EBI’s feedstock production/agronomy program, is to improve the production aspects of bioenergy crops. While other researchers in the program have evaluated miscanthus, switchgrass, and prairie cord grass, Kling is examining which short-rotation woody crops grow best in the Midwest.

“Robinia pseudoacacia is showing great potential as a biomass crop for Midwestern energy production, out-yielding the next closest species by nearly three-fold,” Kling said. “We picked the best crops and moved those forward. Other crops may catch up, but black locust was the fastest out of the gate. We will pursue other crops as well for a number of years, but we want to move to the next step which is on to improved selections.”

As part of the initial study, two-year old seedlings were planted in the spring of 2010, grown over the summers of 2010 and 2011, and were then coppiced in the winter of 2011-2012. By coppicing the plants after a period of growth, or cutting the plants back from a single stem just a few inches from the ground, Kling explained that this process allows the plant to grow back with multiple stems coming from the base and shoots coming up from underground root systems.

“Black locust is effective at colonizing an area, because it freely branches like that,” Kling said. “It’s a good candidate for this kind of treatment, but not all plants will tolerate this process. It forces the plants to essentially grow up as shrubs, with more frequent harvests. By planting much closer together and causing them to branch like that, you are able to fill up available space, intercept light more quickly, and use the field resources more efficiently.”

Researchers assumed they would harvest 3 to 5 years after coppicing, which is comparable to woody crops such as the willow. “After that first coppicing in February 2012, and then after last year’s very early spring, the black locust was growing quite rapidly. It was already a foot tall when we had that freeze in the middle of April, which froze them back to the ground. They began to regrow and put out new shoots in May. By the end of last season, the plants were nearly equivalent to the first two years’ growth,” he said.

This spring, a preliminary check on the black locust crops, which included harvesting 3 plants from the edge of the field, produced a yield of 12 to 13 mega grams per hectare (Mg ha-1), which exceeded what was produced over the first two years’ growth, Kling said.

This rapid growth is what distinguished the black locust from other woody plants in the study.

“We are now looking at harvesting every 2 years rather than every 3 to 5 years as we first assumed,” Kling explained. “This would allow producers to get some payback a lot quicker from their investment.”

Based on these encouraging findings, Kling said two new experiments were started this spring, through the EBI, both looking at different germplasm for black locust crops. In the first, Kling said seedlings were ordered from 10 different commercial sources across 8 states.

“We wanted to sample as much commercial germplasm as we could to see if some are faster growing,” he said. “For example, in Hungary, with appropriate selection, researchers were able to improve yield by approximately 25 percent compared to unimproved black locust. We’re certainly in our infancy yet in terms of trying to improve and select for improved yield, but you’ve got to start somewhere and looking at different germplasm sources is one way to do that.”

The second experiment involved obtaining seed sources internationally through the USDA, including seeds from Afghanistan, Uzbekistan, and Iran. Seeds were also taken from the site of a remediated quarry area in Vermillion County where they found native black locust growing.

The seeds and seedlings for the two new evaluations were treated in greenhouses over the winter, and then planted in EBI fields this spring. Kling said he and the other researchers will evaluate whether to coppice the plants at the end of 1 or 2 years.

“Illinois has a lot of land that is subpar for corn and soybeans, such as the southern part of state and northern parts of the state along rivers. Black locust could be cultivated along some of that area in large acreage. This would be well-suited to smaller producers who want to generate some of their own fuel,” he said. “We do have some producers out there who are looking at alternatives, and there are a lot of farmers who have riparian areas that could potentially grow black locust as a minor crop, in central Illinois we’re not going to see 100-acre lots of black locust growing, though.”

Kling and his team will present the findings from their evaluations at the EBI Feedstock Symposium program in August.

The Energy Biosciences Institute is a public-private collaboration in which bioscience and biological techniques are being applied to help solve the global energy challenge. The partnership, funded with $500 million for 10 years from the energy company BP, includes researchers from the University of California, Berkeley; the University of Illinois at Urbana-Champaign; and the Lawrence Berkeley National Laboratory.
