Pay Attention to Stewardship Requirements for Biotech Grains

October 28, 2014

By Charles Hurburgh, Department of Ag and Biosystems Engineering

Most of us have been following developments in biotechnology approval for many years. The most recent issue is the non-approval of certain corn events by China. Viptera (MIR162) corn has not been approved there since its introduction in 2010; Duracade, new this year, is in the same situation. The greatest impact of the Chinese situation is on distillers grains from ethanol production. China is a major importer of dried distillers grains with solubles (DDGS); much less so for whole corn.

One Oft Forgotten Important Fall Chore – Sampling Fields for SCN

October 16, 2014

By Greg Tylka, Department of Plant Pathology and Microbiology

Crisp, clear fall days are perfect for splitting firewood, tilling the garden under and collecting soil samples to check fields for the soybean cyst nematode (SCN).

Although soil sampling for SCN might not be on most people’s list of favorite autumn chores, fall is a great time to sample fields for this pest. Reasons to sample for SCN include to check for the presence of the nematode in fields and to monitor SCN numbers in fields known to be infested with the pest.

Fall Nitrogen Applications and Soil Temperature

October 13, 2014

By John Sawyer, Department of Agronomy

If you are considering fall application of anhydrous ammonia to corn fields (the only nitrogen fertilizer recommended for fall application), remember to wait until soil temperatures cool to 50° F and continue to trend colder. The same guidance applies to manure with high ammonium N content, like liquid swine manure.
