Here is the latest update on soil nitrate levels in the top foot. An interesting note is that the highest site right now is a sand knoll. In late July and early August there were some fields that were burning up due to lack of moisture, lack of N, or both. The leaf burn goes past the ear leaf in some fields while others still have virtually none.
Here’s the chart.
