Testing Wisconsin P index assessments across cropping systems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Managing agricultural runoff phosphorus (P) often requires understanding management effects on both dissolved P (DP) and particulate (sediment‐bound) P (PP). The Wisconsin P index (WPI) allows producers to assess land management effects on runoff P by estimating annual P losses in mass per unit area.

Delaying application and injecting nitrogen fertilizer with urease and nitrification inhibitors decreased nitrous oxide emissions and enhanced corn yields

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Early season nitrous oxide (N2O) emissions following nitrogen fertilizer application can be significant if spring rains lead to anaerobic conditions before the crop is established and able to utilize the applied N. However, delaying fertilizer application by 4‐5 weeks after planting usually results in warmer temperatures which promote ammonia (
