An ag educator says farmers could use a way to measure nitrogen credits from groundwater.
Retired Mid-State Technical College instructor Mike Sabel tells Brownfield the Wisconsin Nutrient Management Planning System called SNAP+ has no way to accurately account for any possible nitrogen available in irrigation water. “One of the concerns is that if we test the water today, and it ends up having ten parts per unit of nitrogen, what is it going to be when we go and irrigate maybe a month from now or two months from now?”
Sabel says farmers could take nitrogen credits from the applied water if they could constantly monitor the groundwater source because those nitrogen levels can fluctuate.
