Yield of corn, measured in bushels per acre, is something that farmers strive to maximize each year. And while some components are set based on the genetics of the hybrids planted and environmental conditions (weather, soil type, water holding capacity, etc.), there are numerous management practices that can positively influence the yield of corn.

In the fall of 2006, I visited a farmer in SE Missouri. He made mention of his West Farm yielding almost 250 Bu./A. I quickly commented about that outstanding yield and how that must be great for him. The conversation paused, before he said something that has stuck with me ever since. “I don’t care if this farm ever makes 250 again if we can’t get the rest of the farms to make 150.”

As we know all too well, each year of crop production gives us different challenges and opportunities. And as we continue to increase our knowledge and efficiencies of crop production, we continue to be humbled by new pests that rob our fields of yield. Two diseases in particular that have been discovered recently include Red Crown Rot of soybeans and Taproot Decline of soybeans. Both diseases were observed in the early 2000s in the Delta region of the United States. They have since migrated north and have been identified in most soybean growing states of the Midwest.

The 2019 calendar year is coming to an end and the adverse effects to soils resulting from this crop season will loom for years to come. Heavy rain in the spring meant fields were planted in less than ideal conditions. This was followed by a series of production practices being conducted in less than ideal conditions — leading to soil compaction and surface ruts. The immediate thought is to run out and deep rip to remove compaction and fill ruts, but careful thought should be given to the process to provide benefit to the next crop year, but also avoid lasting issues for years to come.
