With grain prices hitting record highs, a lot
of farmers are removing land from the federal Conservation
Reserve Program. The CRP pays farmers to stop growing
crops on poor land and instead grow trees or grass cover.
That creates habitat for wildlife. The US Department of
Agriculture, which runs the program, says the CRP is still
in good shape. Katherine Glover reports some conservationists
disagree:

When the Conservation Reserve Program started in 1985, David Schoenborn was among
the first on board.

He stopped farming some of his land and let natural cover grow. The U.S. Department of
Agriculture paid him. Usually land that wasn’t the best farmland or land that was prone
to erosion was set aside for the program.

Conservationists say CRP has been great for reducing soil erosion, improving water
quality and restoring wildlife habitat.

But this year, for the first time, Schoenborn is letting some of his CRP contracts expire.

“It’s not a bad program, but the payments have to be more to keep them in line with the
rest of the farming economy.”

Corn and other grain prices are at record highs. So a lot of farmers are taking land out of
CRP and plowing it up. The program lost more than two million acres last September.

It could have been much worse. Originally sixteen million acres were set to expire in ’07.
But, in 2006 the USDA offered landowners the option to renew their contracts. About 80
to 85 percent of the land was re-enrolled.

The USDA is focusing its conservation efforts towards environmentally sensitive lands
and critical wildlife habitat.

Perry Aasness is the state director for the USDA Farm Service Agency in Minnesota.

“We’re not enrolling whole fields of land anymore, but there are still conservation
programs which we call the continuous CRP and that primarily focuses on really
targeting buffer strips, waterways, and that sort of thing.”

The targeted programs pay more than the general CRP contracts, making them more
attractive to farmers. Schoenborn, for example, is reenrolling eligible lands in these
targeted programs.

Altogether, the various programs have about 34 million acres enrolled. This is slightly
above the average enrollment for the past ten years, but less than the 39 million acres
authorized by Congress. Aasness says the program is still in good shape.

“I think the overall percentage of land going into production from CRP is pretty
minimal.”

But conservationists have a different perspective. They want to see as much land as
possible enrolled in CRP.

Dave Nomsen is with the conservation group Pheasants Forever:

“Frankly I think the program is more in doubt than it ever has been. It’s great that
farmers are benefiting from record crop prices but it’s making it a real challenge to keep
conservation as part of that agricultural landscape.”

And political pressure is part of that challenge.

The American Bakers Association even asked the government to let CRP contracts expire
early so farmers can plant more grain. This would hopefully lower the price of flour.

But a huge reduction in CRP acres is unlikely. Both Republicans and Democrats support
CRP.

Dave Nomsen with Pheasants Forever says the problem is finding enough money to make
it worth it to farmers.

CRP payments do change over time depending on the market. But Nomsen says they
haven’t kept up.

“It’s been lagging behind by several years. We just don’t have the money to raise it up to
an equal basis, but if we can get those payments high enough the long-term nature of the
contracts, the many, many other benefits of the program will hopefully sell the program
for farmers and landowners.”

Farmer David Schoenborn says payments vary, but generally he gets between 75 and 90
dollars an acre. By planting corn, he thinks he could make at least $400 an acre. But he’d
stay in CRP if payments increased just 30 percent.

That’s not likely. So chances are that more farmers will be putting land that’s set aside
for wildlife back into crops.

Study: Biofuels Grow Dead Zone

There’s another possible downside to the national

There’s another possible downside to the national
boom in the production of corn-based ethanol. A new
study says increased ethanol production would further
pollute the Mississippi River and Gulf of Mexico. Chuck
Quirmbach reports:

Most of the ethanol currently made comes from corn grown in the central part of
the US.

Chris Kucharik is part of a team of researchers that has been studying
what agricultural fertilizers do to the Mississippi River Basin. Kucharik says,
based on his study, ramping up the growing of corn for ethanol would increase
nutrient pollution in the river by 10 to 20%.

“That pretty much will make it impossible for us to reach a goal of reducing
nitrogen export by the Mississippi River.”

Kucharik says nitrogen pollution already contributes to a huge dead zone in the
Gulf of Mexico. The area is depleted of oxygen. He says his prediction of more
problems may not come true if a lot of ethanol production is switched to crops
that don’t need much artificial fertilizer.

Factory Farms – Water Pollution

Transcript

(sound of giant fans)


About a thousand cows are in this building, eating, lolling around, and waiting for the next round of milking.


There’s a sharp smell of manure hanging in the air. Big fans are blowing to keep the cows cool, and to keep the air circulated.


Stephan Vander Hoff runs this dairy along with his siblings. He says these big farms are good for consumers:


“We’ve got something here and we’ve been able to do it in such a way that we’re still producing at the same cost that we were fifteen years ago. It costs more now for a gallon of gas than a gallon of milk. And so, that’s something to be proud of.”


Vander Hoff’s dairy produces enough milk to fill seven tanker trucks everyday. They also produce a lot of waste. The cows in this building are penned in by metal gates. They can’t go outside. So the manure and urine that would normally pile up is washed away by water.


Tens of thousands of gallons of wastewater are sent to big lagoons outside. Eventually, the liquefied manure is spread onto nearby farm fields. It’s a challenge for these farmers to deal with these large pools of liquid manure. The farther they have to haul it, the more expensive it is for them. Almost all of them put the manure onto farm fields.


It’s good for the crops if it’s done right, but if too much manure is put on the land, it can wash into streams and creeks. In fact, this dairy has been cited by the state of Michigan for letting their manure get into nearby waterways.


(sound of roadway)


Lynn Henning keeps a close eye on Vander Hoff’s dairy.


(car door opening and closing)


She steps from her car with a digital camera, and a device that measures water quality.


(sound of crickets and walking through the brush)


She weaves her way down to the edge of this creek.


“This is the area where we got E. coli at 7.5 million.”


High E. coli levels mean the water might be polluted with dangerous pathogens. Lynn Henning is testing the creek today because she saw farmers spreading liquid manure on the fields yesterday. Henning is a farmer turned environmental activist. She works for the Sierra Club and drives all over the state taking water samples and pictures near big livestock farms.


Henning says she got involved because more of these large animal farms expanded into her community. She says when the farmers spread the liquid manure, it can make life in the country pretty difficult:


“The odor is horrendous when they’re applying –we have fly infestations–we have hydrogen sulfide in the air that nobody knows is there because you can’t always smell it. We have to live in fear that every glass of water that we drink is going to be contaminated at some point.”


Water contamination from manure is a big concern. The liquid manure can contain nasty pathogens and bacteria.


Joan Rose is a microbiologist at Michigan State University.


“If animal wastes are not treated properly and we have large concentrations of animal waste going onto land and then via rainfall or other runoff events entering into our water – there can be outbreaks associated with this practice.”


Rose tested water in this area and found high levels of cryptosporidium that likely came from cattle. Cryptosporidium is the same bug that killed people in Milwaukee back in 1993. Rose says livestock farmers need to think more about keeping these pathogens out of the water. But she says they don’t get much support from the state and researchers on how best to do that.


For now, the farmers have to come up with their own solutions.


(sound of treatment plant)


Three years ago, the state of Michigan sued Stephen Vander Hoff’s dairy for multiple waste violations. The Vander Hoff’s settled the case with the state and agreed to build a one million dollar treatment system. But Vander Hoff isn’t convinced that his dairy was at fault, and thinks that people’s concerns over his dairy are overblown:


“If we had an issue or had done something wrong the first people that want to correct it is us. We live in this area. So why would we do anything to harm it?”


Vander Hoff is upbeat about the new treatment system. He says it will save the dairy money in the long run.


The Sierra Club’s Lynn Henning says she’s skeptical of the new treatment plant. She’ll continue to take water samples and put pressure on these farms to handle their manure better. In the end, she doesn’t think these big farms have a place in agriculture. She’d rather see farms go back to the old style of dairying, where the cows are allowed to graze, and the number of animals isn’t so concentrated.


But farm researchers say because consumers demand cheap prices, these large farms are here to stay and there will be more of them. Because of this, the experts say we can expect more conflicts in rural America.

Searching for New Bio-Diesel Source

The U.S. is looking for ways to depend less on foreign oil and reduce greenhouse
gas emissions. A popular method is so-called bio-fuels. Those are fuels, such as
ethanol or bio-diesel, made from plants. Cleaner burning bio-diesel has been billed
as an environmentally-friendly replacement for our 60 billion gallon a year thirst for
diesel oil. But there aren’t enough crops or land to produce enough bio-diesel to
replace fossil fuel-based diesel. Amy Quinton reports new research is looking at

The U.S. is looking for ways to depend less on foreign oil and reduce greenhouse
gas emissions. A popular method is so-called bio-fuels. Those are fuels, such as
ethanol or bio-diesel, made from plants. Cleaner burning bio-diesel has been billed
as an environmentally-friendly replacement for our 60 billion gallon a year thirst for
diesel oil. But there aren’t enough crops or land to produce enough bio-diesel to
replace fossil fuel-based diesel. Amy Quinton reports new research is looking at
another way to make bio-diesel: using algae:


Bio-diesel is made primarily from plant oils: soybean, canola, rapeseed. Ihab Farag
is a chemical engineering professor at the University of New Hampshire. He climbs
up scaffolding to demonstrate a processor that turns waste oil from the University’s
cafeteria into bio-diesel. Farag says this is more environmentally-friendly than diesel:


“It’s coming from vegetable oil, so therefore it’s cleaner… it doesn’t have the sulfur in it so you
don’t get acid rain issue that you get from diesel, it doesn’t do particulates which are suspect[ed] to be cancer-
causing.”


Almost any diesel engine built in the last 15 years can use bio-diesel, but Farag says
there’s a major drawback: it takes an acre of most crops to produce only 100 gallons
of bio-diesel per year:


“I think it has been estimated that if we are using just something like soybean[s] and want to
produce bio-diesel for the whole country, we need almost an area of land that’s about
two and a half to three times the area of Texas.”


That would be an environmental nightmare because bio-fuels require a lot of fossil
fuels to plant, harvest and process them. They only produce a bit more energy than
the energy needed to make them. It also would put the nation’s fuel needs in conflict
with its food needs. That could drive the price of both sky-high.


So Farag and Master Chemical Engineering student Justin Ferrentino are looking at
another plant. One that’s capable of producing much more oil : algae.
Inside the University’s bio-diesel lab, Ferrentino holds up a glass jar filled with a sea-
green powder:


“This is freeze-dried cells that we’ve grown up in our photo-bioreactor.”


He’s testing different ways of extracting oil from these single-celled algae plants to
produce the most bio-diesel:


“People have projected with micro-algae you can grow somewhere between five and 15,000
gallons per acre per year, so it’s a big difference.”


Compared to 100 gallons per acre of soybeans, it’s a very big difference. Ferrentino
has built a contraption of two small fiberglass tanks, surrounded by florescent lights
and reflectors. It’s called a photo-bioreactor. With the right amount of light, the algae
here grows rapidly:


“When I fill these with growth medium and then add the cells to them and they just
multiply, they divide… they double every ten to 15 hours, when they’re growing
exponentially.”


The more cells, the more oil, and the more bio-diesel. Ferrentino’s photo-bioreactor
is small, producing only a tenth of a gram of bio-diesel. But build one on a larger
scale where there’s lots of sunlight, like the desert Southwest, and it could potentially
produce thousands of gallons on just an acre of land.


And Farag says because carbon is needed to fertilize algae growth, the potential
exists to remove greenhouse gases while simultaneously producing bio-diesel:


“If we can connect it with a wastewater treatment plant, where they have a lot of
waste coming in with lots of carbon in it then you can consume the carbon to grow
the algae and at the same time clean up the wastewater.”


But skeptics say one of the biggest challenges is making algae production
economical. Commercial production would initially yield fuel that could cost between
20 and 50 dollars a gallon. Ferrentino recognizes the drawbacks, but says their
research is worth pursuing:


“I think that our energy needs are not necessarily going to be solved with a magic
bullet, but I think this is certainly one part of it, being that you don’t need arable land
you have the added benefit of maybe being able to use the carbon from flue gases
from power plants, maybe being able to treat wastewater. So, it has some significant
added benefits so it could be one piece of the energy picture.”


But growing algae in the desert or anywhere else doesn’t have the kind of political
appeal that subsidizing farmers to grow soybeans for soy-diesel does. So finding
funding for a commercial-sized algae bio-reactor will face significant obstacles.

Spinach Controversy to Benefit Small Farmers?

Last month, more than 150 people fell sick from spinach tainted with
the E. coli bacteria. The spinach has been traced to a California-
based produce company. While this means trouble for large-scale agricultural
producers, Brian Bull reports the outbreak might help smaller,
independent farmers:


Bill Warner owns an organic spinach farm. He sells his crop at local
farmers’ markets and restaurants in Wisconsin and to some restaurants
in Chicago. Warner says he thinks the E. coli incident will steer
consumers toward smaller, organic farms like his.


“We just will tell people that in every step of the way we
do, we’re eating our spinach. We drink the same well water that we
water with. So it may get people more back to, ‘Y’know we don’t want
the big conglomerate foods, let’s go back to buying from who we
know.'”


Warner says many, if not most, organic farmers are extra careful.
They don’t seal their spinach in bags, and don’t use manure in their
fertilizer. Instead, they use a vegetable-based compost and wash
their greens with clean well water. Warner says this helps alleviate
the risk of E. coli bacteria contamination.

Cities Cope With Pesticide Pollution

Today, we continue our series on pollution in the heartland. Farm pollution is one of the biggest
contamination problems in the country. But unlike other industries, there are very few pollution
restrictions on agriculture. In the second story of our week-long series, the GLRC’s Lester
Graham reports when cities clean up pollution from pesticides the cost ends up on their citizens’
water bills:


Every city in the Corn Belt that gets its water from surface supplies such as lakes and rivers has to
deal with pesticide contamination. For the most part, the pesticide levels are below federal
standards for safe drinking water. But water treatment plants have to test for the chemicals and
other pollutants that wash in from farm fields.


Some cities have had to build artificial wetlands or take other more expensive measures to help
reduce pollution such as nitrogen, phosphorous and pesticides.


Craig Cummings is the Water Director for the City of Bloomington, Illinois.


“Well, you know, it is an expense that, you know, we would rather not bear, obviously. We
don’t, you know, particularly like to pass that on to our customers. But, again, it’s understood
that we’re not going to have crystal clear, pristine waters here in the Midwest. But, that’s not to
say that we should stick our head in the sand and not work with the producers. At least here in
our little neck of the woods we think we have a great working relationship with the producers.”


Part of that working relationship is a liaison with the farmers.


Jim Rutheford has worked with farmers in the area on soil conservation issues for decades. He’s
showing me the artificial wetlands that the City of Bloomington is monitoring to see if it can help
reduce some of the contaminants that end up in the city’s water supply. The wetlands reduce
nitrogen runoff and filter out some of the pesticides such as atrazine that otherwise would end up
in Bloomington’s lake.


“The atrazine was used back several years ago in high concentrated amounts. Its effects were if
you get a flush of rain after your atrazine is put on, it comes into the lake.”


Rutherford says for a very long time atrazine has been popular with corn farmers.


“It’s the cheapest, but it’s also gives more problems as far as water quality is concerned.”


Because atrazine has been so popular, a lot of farmers use it and it’s polluted some lakes to the
point they exceeded safe drinking water standards.


In one test during spring applications of atrazine, National Oceanic and Atmospherica
Administration scientists found so much of the chemical had evaporated from Midwest farm
fields that rain in some parts of the East Coast had atrazine levels that exceeded safe drinking
water levels.


But atrazine levels have been going down. It’s not so much because of artificial wetlands or
because farmers are concerned about pesticide pollution, although some of them have expressed
concern. Atrazine has not been as much of a problem because more and more farmers are
switching to genetically modified crops such as Round-Up Ready soybeans and more recently
Round-Up Ready corn. The Monsanto seed is genetically altered so that the Monsanto pesticide,
Round-Up, can be applied to the fields and not hurt the crops. And Round-Up doesn’t cause the
kind of water pollution that atrazine does.


Mike Kelly is a farmer who’s concerned about reducing storm water runoff from farm fields.


“A lot of the herbicides that we’re using attack the plant, not the soil. For example, Round-Up
does not hang around in the soil. Now, I do still use atrazine. It does attach to soil particles. But
there’s where the advantage of no-till–the soil staying put in the field–as you said, we’re not
getting as much erosion, so it stays put and breaks down the way it’s supposed to.”


Kelly use a conservation tillage method that doesn’t plow up the soil the way traditional methods
do. That means less soil erosion so pesticides aren’t as likely to end up in waterways. And Kelly says low-till and no-till methods are beginning to get a hand from nature:


“Definitely conservation tillage and no-till is going to help keep herbicides in the field. Again, he
do see increased infiltration through better soil structure and also through earthworms coming
back, creating holes about the size of a pencil three to four feet deep in our soils. That is a nice
avenue for water to infiltrate rather than run off.”


And if more of the water percolates down into the soil, less of it is going to end up polluting
water supplies such as the City of Bloomington’s lake.


Water Director Craig Cummings says they city encourages voluntary efforts like Mike Kelly’s.
Cummings says the city depends on the farming community too much to point a finger, accusing
farmers of pollution.


“We recognize that we’re in the breadbasket of the world here. And we’re going to see with the
kind of agricultural practices that we have here in the Midwest or United States, we’re going to
see some of these contaminants.”


Cummings says it’s not a matter of eliminating pesticide contamination at the source, but
rather a matter of the city keeping levels low enough that the water is safe to drink.

A More Efficient Way to Make Ethanol?

With that
in mind, many Americans have begun to think about biofuels from domestic crops. Biofuels such as corn ethanol and soy diesel are the most popular right now.

The cost of oil is topping out near $70 a barrel and the nation is sending billions of dollars to unstable foreign countries to get it. With that in mind many Americans have begun to think about biofuels from domestic crops. Biofuels such as corn ethanol and soy diesel are the most popular right now, but researchers are looking into plants that don’t require the fertilizers and pesticides those crops need. The GLRC’s Richard Annal reports on one crop that could make ethanol much more efficiently:


(sound of pouring liquid)


Researcher Timothy Volk is showing me some liquid that is on its way to becoming biofuel.


“So what comes out of this is a brown liquid.”


This murky brownish substance contains sugars that have been extracted from wood chips. Separating sugars from organic materials is an essential part in the production of the biofuel ethanol, and a new method being developed at the School might revolutionize that process. This lab is at the School of Environmental Science and Forestry in Syracuse, part of the State University of New York system. Everybody just calls the school ESF. What makes the process at ESF different is the use of water instead of harsh chemicals as a means of extracting sugar and the use of wood from a type of willow as stock material.


The extracted sugars are then fermented and used to produce ethanol. Mix 85 percent ethanol with 15 percent gasoline and you’ve got E-85. Several models of cars can burn E-85. It burns cleaner than petroleum based products, and reduces the dependence on foreign oils.


ESF’s Timothy Volk says this method differs from others being used, creates several by- products, and leaves very little waste material.


“What’s left over still looks like a wood chip. That could go to the paper industry, and you could still make paper out of it, or you could use that wood chip to produce renewable heat and power. One of the beauties of this is that from a ton of hard wood chips from the forest or willow or where ever it comes from you’re making multiple products and there’s not a lot left.”


For stock material ESF researchers are experimenting with the use of the willow shrub tree. This plant is native and grows to over ten feet tall. The researchers say willow beats corn hands down. You have to burn fuel to plant corn every year. Corn requires fossil fuel-based fertilizers, and you only use the corn kernels rather than the whole plant to produce ethanol.


Jim Nokas is one of the lead researchers on the project. He sees the willow shrub as much more commercially viable than corn-based production.


“The best calculations we have for every unit of energy put into this process you get anywhere from 11 to 15 units of energy out. Compared to the best data available for corn, for every unit of energy put in, one would obtain 1.67 units of energy out.”


In other words, producing ethanol from willow is about ten times more efficient than using corn.


Tom Linberg is a commissioner with the New York State Department of Agriculture. Linberg says he’s excited by the prospect of wood-based ethanol production, and sees growing a low maintenance crop like willow as a way for farmers to earn extra cash.


“I think it’s something that could provide an option for a lot of farmers or land owners to use vacant land. Try and get some income off of it whereas they might otherwise not be getting income off the land. It’s a fairly low impact crop. You know, you plant it once and you don’t really need to do anything else with it, and this is something they could have on the side. Brings in some extra income and, again, helps keep that land productive.”


Willow can be harvested 6 to 7 times before replanting is necessary. It has a year long growing and harvesting season, and provides high yields. With about 2 million acres of dormant farmland in New York alone that could be dedicated to willow production, Volk believes growing willow for ethanol would have a positive effect on the local economy that buying foreign oil cannot offer.


“The real benefit here then is we build them here and it’s locally produced material, so you buy it from the land owners, or the farmers that are producing willow, the people that own wood lots. You buy all that material locally from the local community. You produce the ethanol and hopefully then we are using it locally in the community, and instead of sending energy dollars out of the state we cycle them around the local community and get lots of benefits associated with them.”


The researchers say the willow-to-ethanol process will be ready for commercial application within two years, and if it proves commercially viable the timing couldn’t be better. With ethanol plants being built across the nation, the wood method could become an efficient alternative to corn-based production in many states.

Farmers Watch for Soybean Rust

All eyes are on the south right now for signs of a potentially
devastating fungus that attacks soybeans. A serious outbreak there could
bring soybean rust to the Midwest – where most of the nation’s soybeans are
grown. The Great Lakes Radio Consortium’s Tracy Samilton reports:


Soybean rust spores are carried on wind currents, so it is easily spread.
So far this year, only Georgia has had a small outbreak.


Ray Hammerschmidt is a plant pathologist at Michigan State University. He
says every step is being taken to protect soybean crops, including dotting
the Midwest with what are called sentinel plots.


“And once a week, starting in a few weeks, each of these plots will be scouted very intensively, looking at at least a hundred plants, looking for any signs or symptoms of the disease.”


Advance warnings will allow farmers to apply fungicide to their crops as
soon as possible. Soybean rust can’t overwinter in the cold north.
So if southern states have good luck – or do a good job treating it – it’s less
likely to make it here.

Rekindling Corn Stoves

Fuel prices are higher this winter… but corn prices are down. That’s kindling a demand for corn stoves in some parts of the country. The Great Lakes Radio Consortium’s Shamane Mills reports:

Fuel prices are higher this winter, but corn prices are down. That’s kindling a demand for corn
stoves in some parts of the country. The Great Lakes Radio Consortium’s Shamane Mills reports:


I always thought corn was something you ate. But I’m watching as my brother-in-law is stoking
his stove with golden kernels…


“In my case I use five gallon pails of corn, then just pour in slowly…”


(sound of kernels spilling into hopper)


I’d never seen a corn stove and my brother-in-law, Steve Springer, says he never thought he’d use
one. Once he did, he was hooked.


“Well, one thing about it is, it’s a renewable resource. Being a farmer myself, it’s something we
grow ourselves. This was in our home when we purchased the home – never had any exposure to
it. Since then, I like it immensely. Kicks out lot of heat.”


Corn stoves first became popular in the 1970’s when corn prices plummeted. There were
problems with the early stoves. Hardened clumps of burned corn, called clinkers, had to be
cleaned up and the corn didn’t burn efficiently.


Today, the stoves are making a resurgence because corn prices are down. New corn stoves are
better than the ones back in the 70’s. The stoves now have an agitator to stir the corn for a more
even burn and fewer clinkers.


Ed Bossert sells corn stoves at a store near where the Springers live. He says business is brisk.


“A lot of people come in to save money, a lot of people come in because it’s a renewable
resource, a lot of people come in because the pollution factor is basically nothing.”


Corn stoves produce less carbon dioxide and soot than burning wood or coal, so they seem more
environmentally friendly. But critics point out that the farm machinery used to grow the corn
burns fuel and generates pollution, so any gain from a cleaner burning fuel may be lost during
planting and harvesting.


While the environmental argument simmers, sales of corn stoves continue to heat up. Bossert says
he now sells as many corn stoves as he does wood stoves.


In larger cities such as Madison, Wisconsin the corn stoves don’t sell as well. At Top
Hat Fireplace & Chimney, only three customers have purchased corn stoves despite the best
efforts of sales staff like Mark Gilligan. Showing off the store’s one and only corn stove model,
he says it’s easy to maintain….


“They actually locate down below an ash drawer. That actually sits down below. There isn’t a
whole lot of ash from these pellet and corn stoves because it uses most of it up.”


Most corn stove dealers say a bushel or two a day will keep the cold away. With corn about two
dollars a bushel, that can seem like a bargain compared to natural gas prices, which are 20%
higher this year. But the initial cost of residential corn stoves can be steep.


Craig Tawlowicz owns Countryside Heating in north-central Wisconsin. He says new corn
stoves can cost two thousand… on up to six thousand dollars.


“So this is a long term investment. Most of the time, turn around savings, usually five to six
years pays off your investment.”


Wood stoves are not only more traditional, but they’re generally cheaper. So, wood stoves are
more popular. At Hearth and Home Fireplaces, Claire Barton says despite that… more customers
are considering corn stoves.


“It certainly makes sense for someone who has grain available to them and many of them will
burn corn as well as oats, wheat, barley, cherry pits. Things like that.”


The National Corn Growers Association promotes a lot of corn products. You’d think corn stoves
might be one of them – but spokeswoman Mimi Ricketts says it’s not one of the 600 items the
group touts.


“The National Corn Growers Association determines its issues based on priorities of member
states. Corn stoves is not one that’s been put on our radar screen. We are aware of them but we
have not actively promoted corn stoves.”


That’s probably because compared to other buyers of corn, such as livestock farms, corn syrup
processors and ethanol makers, corn stoves just don’t use a lot of corn. It’s not considered a big
market for farmers.


Instead, the big sales are going to those who make or sell the corn stoves. And because farmers’
harvest was so large this fall, corn stove retailers have found their cash crop this winter.
