NC Iowa | I would be reluctant to try that.
In our area, the lowest ground typically has the highest OM, makes sense. But, why did it get that way... essentially it is not a healthy environment, more prone to being flooded/saturated causing anaerobic conditions, usually has more compaction, not ideal for mineralizing N at a higher rate then a neighboring soil with less OM but has better drainage.
I have seen this on some N tests in my fields, the area that first showed N deficiency was a lower area with OM readings 1-2% higher then the rest of the field. Now that I have tiled the field out, it may respond differently. | |

Corn N recs based on OM?
