Although growing corn in rotation has long been preferred by farmers, some are switching to more corn-on-corn production for economic reasons. Those taking this step may benefit from a review of the issues that will likely be encountered when growing corn crops back-to-back.

A new issue of Crop Insights from Pioneer Hi-Bred International Inc. addresses best corn-after-corn production practices, with focus on hybrid selection, plant and seed technologies, and high crop residue challenges. These challenges include cool, wet soils at planting, increased disease and insect levels and tie-up of nitrogen. Other issues are soil compaction, weed management and moisture stress.
