Application Requirements to Meet Agronomic Rate
1. The timing of sludge application should be relevant to the time when selected crops will uptake
nitrogen.
2. Splitting applications of the total allowable loading (from worksheet) should be performed consistent
with typical crop management practices.
3. Crop removal (e.g., hay harvesting, yield goal) shall be integral to site management.

Once the mineralization rate becomes less than 3% (i.e., 0.03), no net gain of PAN above that normally obtained from the mineralization of soil organic matter is
typically expected. Therefore, additional credits for residual sludge N do not need to be calculated.
