How to Calculate Value of Nutrients in Litter
Step 1: Cost of Commercial Fertilizer
Call your local fertilizer dealer for current fertilizer prices required below.
a) Determine Cost Per Ton of N (Urea) Urea Analysis: 46-0-0 $
b) Determine Cost Per Ton of P2O5 (DAP) DAP = Diammonium phosphate fertilizer DAP Analysis: 18-46-0 $
c) Determine Cost Per Ton of K2O (Potash) Potash Analysis: 0-0-60 $
Step 2: Litter Analysis from Lab
Enter lab test results from your litter sample in the required fields below. Manure Test Values (as-is basis)
lbs. N per ton of litter
lbs. P2O5 per ton of litter
lbs. K2O per ton of litter
Step 3: Calculate Final Values
Based on estimated 70% availability of the N in litter.
