Nutrient Budget for Corn Silage

Throughout the spring the farm keeps track of how much manure and fertilizer they apply to their fields. They use a nutrient budget to figure out where they are deficient or where they have over applied. Based on nutrient needs for corn silage a typical nutrient budget may look like the one below.

Nitrogen (lbs/acre) Phosphorus (lbs./acre) Potassium (lbs/acre)
Corn Silage Needs: 150 80 120
Manure Application 45 60 75
Fertilizer Application 30 20 10
Deficit/Surplus - 75 0 - 35
