Limit application of the fertilizer so that it meets projected crop or plant needs; 2. Time application of the fertilizer to coincide to maximum crop or plant uptake; 3. Apply the fertilizer by a method designed to deliver nitrogen to the area of maximum crop or plant uptake; 4. Manage and time application of irrigation water to minimize nitrogen loss by leaching and runoff; and 5. Use tillage practices that maximize water and nitrogen uptake by a crop or plant.
