Knowledge about the soil nitrogen (N) supply potential of fields or areas within fields is essential for improving N management. Previous work in New York has shown the usefulness of the Illinois soil N test (ISNT) with loss-onignition at 500°C (LOI500) adjustment to identify corn fields with low versus high soil-N supply potential. However, spatial variability in ISNT-N and LOI500 can influence the classifications.
