Given below is a worksheet to calculate the value of broiler litter based on prevailing retail
selling prices of common fertilizer materials containing nitrogen (N), phosphorus (P) expressed as
(the oxide expression used in the fertilizer industry), and potassium (K)
expressed as K2
O (fertilizer recommendations are made on the oxide basis for both P and K).
For more information on the litter N,P, and K availability to crops, go to our publication:
Calculating the Fertilizer Value of Broiler Litter
Step 1: Cost per pound of available nutrients:
Call your local fertilizer dealer for current fertilizer prices in your area. If the fertilizer dealer provides a
price for a blend such as 17-17-17, ask for the prices of the individual fertilizer materials making up the blend.
Select a fertilizer and enter the current
market price in the box beside it. The price for the corresponding nutrient will be calculated for you.
Step 2: Determine the equivalent N, P2O5, and K2O values per ton of litter:
Typical analysis values will appear below based on average broiler litter analysis results at our laboratories over the past three years.
Optionally, you may enter the litter N, P2O5, and K2O values shown on your animal waste report.
Step 3: Add the total fertilizer values for N, P, and K in dollars per ton of litter:
The total of the nutrient values for N, P, and K will give you the total value of broiler litter.
