Abstract
Nitrogen and phosphorus fertilizers were applied to range vegetation at five locations at rates ranging from 475 to 705 kg/ha N with or without from 380 to 545 kg/ha P. The addition of fertilizers increased average water-use efficiency at all locations. Average magnitude of the increase in relation to unfertilized controls was: control, 33.3 kg/ha dry matter produced per cm of water; P, 37.0 kg/ha/cm; N, 52.3 kg/ha/cm; and, N+P, 73.4 kg/ha/cm. Fall soil moisture had the greatest influence on yield of control and P-treated range vegetation, whereas June precipitation had the greatest influence on yield of N- and N+P-treated range vegetation.Keywords
