Effect of Nitrogen, Phosphorus and Potassium Fertilizer on the Economics of Producing Bluegrass Forage'1
- William M. Walker,
- John Pesek and
- Earl O. Heady2
Responses of a native bluegrass sod to topdressed applications of N, P and K fertilizer rates varying jointly were used to fit a forage yield equation and to calculate iso-yield curves and least cost fertilizer ratios. It was then shown how these data and equations may be used in determining levels of fertilizer for optimum beef production and estimating the price of beef needed to justify fertilization of this type of sod.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
