Utilization of runoff water to produce additional forage is essential in a balanced range management program. This. is especially true in the northern Great Plains where limited and erratic precipitation results in frequent drought periods. The use of water spreading systems to collect and distribute runoff water over "run-in" range sites has generally resulted in greater forage production (Mooney and Martin, 1956). However, the extra moisture received on several "run-in" range sites on the heavy clay soils of western South Dakota has failed to produce forage in proportion to the amount of moisture available. Poor grazing management and/or low fertility could nullify the benefits ex-1 Contribution from Soil and Water Conservation R e s ear c h Division,

Synopsis The application of N fertilizer to grass resulted in an increase in yield and in the percentage of N, P, Ca, and K. Lime additions increased uptake of Ca and N. Deer preferred grass higher in nutritional value.
