German chemist Justus von Liebig is often credited with ushering in the modern era of soil chemistry and plant nutrition. In the mid-1800s, von Liebigs’ research and discovery led to the development of the first nitrogenbased commercial fertilizer. Since then, soil scientists and agriculturalists around the world have endeavored to understand and manage the use of these fertilizers in corn production. Managing nitrogen (N) for corn production is a difficult task due to the complexities of the nutrient and the hundreds, if not thousands, of factors that influence N in the soil and plants.

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.
