A study was made to determine the effects of variable levels of nitrogen, phosphorus, and potassium upon several species of pioneer and climax range grasses, and to determine if these grasses differ in their ability to grow when supplied with low levels of these nutrients. Five grasses were used. The climax grasses were Agropyron spicatum and Agropryon smithii, and the pioneer grasses were Aristida longiseta, Sporobous cryptandrus, and Oryzopsis hymenoides.
