The amount that this year’s total plant-available N, P2O5, and K2O is over or under adjusted UW-Extension recommended rates is in the Over(+)/Under(-) adj UW Rec row. Under-applications are displayed as negative (-) values. This amount does NOT include carryover P2O5, and K2O from previous years. Note: The N application rate allowed by the 590 standard is under some circumstances higher than UW Extension recommendations, so it is possible to have an overapplication in the Over/Under adj UW Rec row without getting a warning message.
