Certified crop advisers (CCAs) can earn five hours of credit (three hours in soil and water management, 1.5 in pest management, and 0.5 in crop management) by attending a special CCA morning session, that proceeds the afternoon spring field day tour at the Southeast Iowa Research and Demonstration Farm near Crawfordsville on June 15.
Predictive Equations of Alfalfa Quality (PEAQ) monitoring shows alfalfa growth and development running about one week behind normal. Those that usually consider first crop harvest on May 25 need not be too concerned with not harvesting yet.

Fields at this time are most vulnerable to soil erosion because they lack crop residue cover and the crop canopy is not yet present to protect the soil.
An updated and revised Soybean Field Guide contains information on soybean production, integrated pest management, diseases, insects and disorders.

Corn flea beetles have been found feeding on seedling corn in central Iowa. The feeding rarely causes economic damage to established corn, but can sometimes kill corn seedlings with high beetle populations.
Roger Elmore, ISU Extension corn specialist, discusses yellow corn emergence and the benefits to producers who walk their fields gathering information to prepare for next year. Look for the weekly Crop Minute on the right side of the ICM News homepage, under More Resources. Or go directly to the May 16, 2011 interviews (mp3).
ISU researcher needs to collect samples from Iowa soybean fields that have stand establishment problems due to damping off. The samples will provide information for a multi-state research project to identify oomycete pathogens that cause damping off of soybeans.
