More trouble lies ahead for Mississippi River watershed
Twin Cities Daily Planet
A three-hour drive separates the rolling hills of Minnesota's Douglas
County from the front steps of the Bell Museum of Natural History. But a
year after the controversy over "Troubled Waters" — the Bell's film on
farmland pollution in the Mississippi River basin—brought words like
dead zone, hypoxia and nitrogen fertilizer to the attention of the
general public, what's happening in places like west-central Minnesota
provides an insight into what the future holds for the health of the
entire watershed all the way to the Gulf of Mexico.

Chesapeake Bay: Farmers learn about tools that help reduce nitrogen pollution
Daily Press Diggin' In Blog
A U.S. Department of Agriculture soil scientist in Colorado is helping
farmers grow crops with less nitrogen-based fertilizer. Jorge Delgado,
with the Agricultural Research Service Soil Plant Nutrient Research Unit
in Fort Collins, Colo., helped develop a tool designed for fledgling
environmental trading credit programs that reward growers for reducing
nitrogen losses. Known as the Nitrogen Trading Tool, it can be used to
determine how much a proposed management practice may be able to reduce
nitrogen losses, and how much "trading credit" could be earned by
switching to it.

A push to farm smarter — not bigger — to feed the world's hungry
The Christian Science Monitor
With famine in Africa and food prices at record highs, governments and
agencies around the globe are looking to educate small farmers about
more efficient, sustainable agriculture practices. The United States is
rolling out agricultural partnerships around the globe, particularly
through its $3 billion Feed the Future Initiative, led by the U.S.
Agency for International Development. One of its stated goals is "to
leverage $70 billion in private investment in agriculture that improves
sustainable market opportunities and linkages with smallholder farmers."

Study: Organic farming shows long-term profitability
WholeFoods Magazine
Farms that produce organic food are economically viable on a long-term
basis, and are perhaps more profitable than conventional farms,
according to new research by the American Society of Agronomy. The
study, conducted by the University of Minnesota and recently published
in Agronomy Journal, analyzed 18 years of crop yields and other farm
data. Findings included a lower risk of poor returns for organic corn
and soybean crop rotations than for conventional rotations.

Sucking up water, sand in the quest for natural gas
Dallas Observer
For folks in the sandy hills an hour and a half northwest of Dallas,
it's a devil's bargain for gas, water and jobs. The record drought is
forcing farmers in and around Saint Jo, Texas, to tap into well water,
putting added pressure on the Trinity Aquifer. The locals are especially
worried about what is being fed into Mountain Creek with the
construction of EOG Resources' sand mine just 50 yards away. EOG will
soon need to pump large amounts of water from the aquifer for its sand
mine’s primary business — fracking.

Conservation farming threatened by lack of funds in Namibia
The Namibian
A six year conservation farming project in has led to a massive rise in
output for around 400 northern Namibia agricultural farmers who took
part in the trial runs. Statistics show that yield increases at farms
which adopted a conservation approach to agriculture ranged from between
200 to 500 percent. Despite the success of the two phases of the
project, funding has ended and the project's future hangs in the
balance.

Why hairy vetch should interest farmers
Winnipeg Free Press
Cover crops have traditionally been used by organic farmers to produce
fertilizer, writes columnist Laura Rance. A legume crop, which produces
its own nitrogen, such as clover, is planted in the field every second
year or so and then worked into the soil, where it decomposes and feeds
the following year's crop. As it turns out, some of these cover crops,
particularly a legume called hairy vetch, are also good at controlling
weeds.
