Nitrogen management is the key to success in conservation tillage systems that include intensifying your cropping system. In general, N fertilizer should be placed below the residue to avoid the loss of nitrogen through volatilization or runoff. Take credit for N from mineralization and legumes .

Legumes can contribute much greater levels of nitrogen.
