Estimating Animal Waste Applications to Supply Crop Nitrogen Requirements1
- A. C. Mathers and

An equation was developed which estimates the amount of animal waste required to supply the desired amount of N for crops. This equation was based on annual mineralization rates which varied with time after application and with N content of the waste. When we calculated waste requirements to supply N needs using the equation, values were satisfactory for wastes containing 4% or less N. Residual N in soil fertilized with animal waste was closely correlated (r = 0.92) with values predicted by the equation.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
