Researchers examined how crop tillage, rotation or crop residue removal can affect the chemical composition of water draining from farm fields.
How do nutrient management practices influence nitrate-N loss in subsurface drainage?
A multi-year, replicated plot subsurface drainage study monitored drainage water and crop yield. Cover crops have the potential to reduce nitrate loss and increased application of nitrogen in a corn-soybean or continuous corn system has the potential to increase nitrate loss.
