Examples
• 3000 lb (DM) of Vetch as a cover crop can produce 80 lb N/ac.
• Cover crop needs to grow until early May to achieve this much DM.
• How much yield do I give up by planting at this later date?

Corn is king -- and therefore a growing problem
– Increasing dependence on the grain leaves the U.S. vulnerable to drought-induced price spikes in food and fuel.

• In January, China levied export tariffs of 5% for corn, rice and soybeans and 20% for wheat to keep grains from leaving the country.
• The Russian government has increased grain export tariffs by 40% - Jan 30, 2008
• Argentina and other nations also are placing tariffs on grain exports to protect their food supplies.

Versatile, with excellent milling and baking
characteristics for pan bread, HRW is also a
choice wheat for Asian noodles, hard rolls, flat breads, general purpose flour and as an improver
for blending.
The aristocrat of wheat when it comes to
"designer" wheat foods like hearth breads, rolls, croissants, bagels and
pizza crust, HRS is also a valued improver in flour
blends.
Versatile, with excellent milling and baking
characteristics for pan breads, general purpose flour and as an improver
for blending.
Hardest of all wheats, durum has a rich amber
color and high gluten content. I t sets the "gold standard" for premium
pasta products, couscous and some Mediterranean
breads.
The newest class of U.S. wheat, HW receives
enthusiastic reviews when used for Asian noodles,
whole wheat or high extraction applications,
pan breads and flat breads.
A low moisture wheat with high extraction rates,
providing a whiter product for exquisite cakes,
pastries, and Asian-style noodles, SW is also ideally suited to Middle Eastern
flatbreads.

Current Position
• Sherman Reese, former president of NAWG and an Oregon wheat commissioner
"My take is there is not a lot of concern about biotech wheat. The concern is that there is wheat at all," he said.
