A team at the University of Missouri and USDA-ARS used yield data from more than 400 corn fields in Iowa, Minnesota, Nebraska and Indiana to compare county soil maps with Environmental Response Unit (ERU) maps developed in collaboration with DuPont Pioneer.

The U.S. Enviornmental Protection Agency and U.S. Army Corps of Engineers jointly released a proposed rule earlier this year to clarify protection for streams and wetlands under the Clean Water Act.

DuPont Pioneer announced plans for a new grower pilot program that will expand on the input management offerings in its recently launched Encirca^SM Yield services platform to include phosphorous and potassium management.

DuPont Pioneer is launching its new Encirca Yield services platform and enrolling growers today to help them improve timing, placement and management of critical inputs to enhance the overall productivity and profitability of every acre.

DuPont Pioneer has announced a new generation of Web-based field management tools to growers with Pioneer Field360 Select software.

DuPont and its Pioneer Hi-Bred agricultural seed unit said a hybrid wheat technology project has been added to its roster of crop research programs that are advancing into deeper development. DuPont currently is largely focused on genetic improvements to corn and soybeans, as well as enhanced canola and rice.

Though planting corn early often results in higher yields, choosing the wrong planting date can have adverse effects on crop establishment.

Variable rate seeding (VRS) can help maximize overall profits by selecting the best planting rates for each area of the field.
