Nutrient management means managing the amount (rate), source, placement (method of application), and timing of plant nutrients and soil amendments. These steps reduce the potential for nutrients to go unused and wash or infiltrate into water supplies. Nutrient sources include animal manure, sludge, and commercial fertilizers.
How it helps
Improves crop production by budgeting, supplying, and conserving nutrients.
Reduces input costs.
Protects water quality by preventing over-application of commercial fertilizers and animal manure.
Properly utilizes manure, municipal and industrial biosolids, and other organic byproducts as plant nutrient sources.
Protects air quality by reducing odors, nitrogen emissions, and the formation of atmospheric particulates.
Maintains or improves the physical, chemical, and biological condition of soil.
Planning ahead
Have you tested nutrient levels of your soil and livestock manure?
Are organic wastes or sludge available for you to use?
Have you determined realistic yield goals?
Are proper soil conservation measures installed?
Have you accounted for nitrogen credits produced by legume crops?
Tech Notes
Follow the 4Rs of nutrient management:
Select the Right nutrient source, considering what the crop needs, costs, availability, method of delivery, and environmental risk.
Select the Right rate by using the Corn Nitrogen Rate Calculator to determine the recommended Maximum Return to Nitrogen Rate.
Select the Right time by synchronizing nutrient availability with crop demand and reduced environmental risk.
Select the Right place by keeping nutrients where the crop can get to them, where nutrients are least likely to leave the field, and efficiency is maximized.
