Crop rotation with soybeans can reduce the need for nitrogen fertilizer.
Native American’s “three sisters” had great wisdom.
Very true. Farmer’s are going experience a 40-50% reduction in yield without nitrogen though. Then translate that into the supply/demand outcome and people will be looking at a $10 box of cornflakes in 2023.
They used to do that until it became so attractive to raise corn to produce legal moonshine (ethanol). The corn, which is meant to be eaten, was used to destroy car engines.
I don’t think my FIL ever bought much nitrogen. He rotated wheat with soybeans. Irrigated out of the Blue River since the Red was too salty. Worked his butt off and never missed a crop.
