Proceedings of a symposium conducted by the Southern Branch American Society of Agronomy.
Field experiments in Kentucky show significant danger in using the Magdoff nitrate test as presently promulgated. The most serious problem seems to be associated with soils which are less than well-drained. It probably is associated with slower nitrification, greater denitrification, greater leaching and higher nitrogen uptake by corn in those soils. Other problems are differences caused by tillage, a short turnaround time for best results, hugh errors in sampling and variable soils with a field. My viewpoint is that the soil nitrate test will not exactly sweep the South, given the problems associated with it.
