The farmer I help in Lawrence county, TN, doesn’t apply any manure or fertilzer more than 4” deep. The second application of liquid nitrogen happens at about 2-3 weeks after crop emergence, and is laid right on top of the ground, next to the plant row on each side. Some of that is surely lost if there’s a heavy downpour.
The real risks are when the mega corporate farm goes bankrupt. Then all the smaller farms are gone. Better to have 500 farms in a county with busy bulk milk tankers running the roads, than two farms in a county with 50 bulk tank semi's parked by the holding tanks.
