K State and ISU research indicates cover crops and no till practices may actually increase total phosphorus loss from farm fields, indicating nutrient management is needed. Duh! Iowa Learning Farms June 19, 2024 Webinar indicated cereal rye cover crops takes up a lot of excess nitrogen but they found it doesn't give it back so readily when needed by the crop. It was suggested that additional nitrogen be applied during the season to compensate for the cover crop not cooperating with the Iowa Nutrient Reduction Strategy. Round and round this little engine goes, fueled by my tax dollars. References below.
The entire NPK evolution is bullshit. Soil chemistry is not about those three numbers. To actually improve soil, you must have a soil audit.
None of the numbers other than Tracy Merrill ppm mean a damn thing individually. What is important are the ratios. Particular to calcium and magnesium. Obviously, nitrogen, demanding crops need extra. Compost and bird shit, bat shit, and other animal shit and planting after lagumes is the answer.
Phosphorous barely move through the soil. Cover crops are essential to any living soil management practice and one or two species in mid August application. Sure, as fuck isn’t a legitimate cover crop.
