Illinois Soil Nitrogen Monitoring Project

Today I read results from the fall nitrogen soil monitoring project.  It is interesting that nitrogen remaining in the field is not really closely tied to yield.  It does not look like they are correlating test results to soil type.  Soil type would reflect soil conditions.  Soil conditions such as moisture content will play a big role in nitrogen availability.  This project is a step in the right direction, but I hope they will fine tune it to make it more meaningful.
