With 6 to 10 inches of rainfall in May and more predicted in many areas of Kansas, the questions now become: How can I determine if my corn actually needs additional N? Should I be considering sidedressing additional N as soon as it dries up? Should I call in a plane and fly on urea? If I do need more N, how can I determine how much is actually needed?
The U.S. Department of Agriculture (USDA) announced that incentives will resume this summer for farmers, ranchers and forest landowners interested in growing and harvesting biomass for renewable energy.
The true armyworm is a migratory pest from the southern U.S. that feeds on the leaf tissue of early and late vegetative corn. Adult true armyworm moths are attracted to fields that contain living ground cover, which include fields with grassy weeds or cover crops such as rye or grass.
Last week, (May 19-22, 2015), some wireworm activity was noted in south-central Iowa. Ideally, scouting for wireworms should occur prior to planting because there are no effective rescue treatments. However, most people don’t see the impact this pest can have on a corn stand until corn plants emerge.
Farmers that have not completed corn planting may be considering switching from corn to soybean or keeping corn, but switching to an earlier hybrid. Both of these decisions can be complicated and depend on yield and other information that are imprecise estimates and highly dependent on weather conditions the crops experience throughout the rest of the growing season.
