Zealous planting schedules and little sleep frequently characterized farmers’ lives during the last week. While some fields were too wet to work and temperatures careened from 89 to 35 degrees, NASS reported emergence in the corn and soybean crops have continued steady progress in most areas.

Eighty-eight percent of corn and 59 percent of soybeans are planted. Both are ahead of this time last year. According to NASS, topsoil and subsoil moisture are adequate, at 71 and 78 percent respectively. "With seeds in the ground and cool weather and rain possible this time of year, corn growth stage and GDU (growing degree units) accumulation are important considerations, as well as nitrogen management," said Matt Parmer, Asgrow technical agronomist.

"In regards to insect pressure, identifying key times during the growing season when the pressure could occur can aid in focusing when and how to properly scout to determine action thresholds. Every three kernels lost to insects is one bushel of yield lost."

Jeff Nagel, Ceres Solutions, Inc. agronomist, noted areas of some cornfields are showing yellowing and shortened internodes around the V3 to V4 stages. "Recent observations included tight soils and residue concentrations in the seedling zone," he reported.

He also encouraged proper spray tank maintenance: "When spraying foliar nutrients, only mix what can be sprayed that day and end the day with the sprayer empty. It is a good idea to purge the boom with water or air at the end of the day."
