Abstract
This paper entails the economic and biological interpretation of the response of rangeland grasses to nitrogen fertilization. Six sites throughout Utah received graduated rates of fertilizer. The coefficients of the production function
Y = a + bN - cN2
were identified.
An initial production and a carry-over response were identified on sites receiving greater than ten inches of annual precipitation. Optimum fertilization rates may be identified by equating the marginal physical product to the ratio of the price of nitrogen to the price of the forage.
Forage response to nitrogen is reflected strongly in the early growth response in which fertilizer rates of 15 to 120 pounds of nitrogen per acre produce adequate forage for grazing 4 to 18 days prior to unfertilized range.
