On our walk, we came across something we seldom see: a plowed hay field.
We live in the land of corn and soybeans. Occasionally, we'll see a wheat field or an alfalfa field, but they are in the minority.
The man who farms for us rotates between corn, soybeans, wheat and alfalfa. He will keep a field in hay for five to eight years before plowing the soil and planting corn.
The corn crop will get a boost from the nitrogen that the alfalfa produced.
