Brad Carlson with the University of Minnesota says the coming crop year provides an interesting opportunity for farmers looking to scale back on input costs.

“What we found through research over the years is following an extraordinarily dry year, we’ll end up accumulating nitrates in the soil profile. To some extent it would be unused fertilizer, which of course could only be used if you’re growing corn on corn.”

Speaking to Brownfield at the MN Ag Expo in Mankato, Minnesota Wednesday, he says soil mineralizes nitrogen, and when its dry nutrients are suspended.
