We know that P is a critical element required for crop growth and development, and if deficient, the lack of P can significantly reduce crop yield. While application of P fertilizer is common, it is not always required to achieve maximum yield.

Research results from a study led by Extension specialist Fabian Fernandez at the Rosholt Research Farm in Westport, Minnesota show data from 2016 to 2019 for two cover crop systems: winter rye and Kura clover living mulch. The farm is in the Bonanza Valley and has an irrigation system. Read more in this press release from the University of Minnesota.

The limitations of field working days due to wet fields and high wind and temperature continues to limit corn and soybean weed management practices. As we enter July, safe and effective weed management practices begin to diminish rapidly.

More precipitation means less time to apply before planting, or more nitrogen loss in season. Many are turning to canopy sensing technologies to guide fertilizer application rates during in-season applications.

Foliar fungicides are valuable soybean disease management tools. However, when applied in the absence of controllable, yield-limiting plant disease, they are typically not a profitable input. 

EPA and pesticide manufacturers have made it abundantly clear they do not want pesticides applied during an inversion in air temperatures. But that is easier said than done.
