Leaving corn residue on fields provides a protective blanket for soil. This reduces erosion and water runoff by increasing water infiltration. But as good as this sounds, many farmers understandably ask, “How much residue is too much?”
Farmers who select seed corn that best matches the soil in their fields can expect to see up to a 50-bushel-per-acre increase in yield, according to researchers. The best part? This increased yield can come without added input costs.
Many farmers look to save money on the cost of seed corn. The fact is, however, that cutting seed corn costs won’t do much for profits when you look at overall yield.
