Wood et al. measure infiltration and sediment production under two grazing techniques: 1, by doubling the stocking rate on rangeland fertilized by nitrogen, and 2) conventional stocking on unfertilized rangeland in Lincoln County, New Mexico. Infiltration rate and sediment yield, using an infiltrometer to simulate rainfall, along with biomass, foliar cover, surface roughness, and soil bulk density were measured on three unfertilized pastures, stocked at 2.5 ha/AU and three fertilized pastures, stocked at 1.2 ha/AU. Although there was a large amount of variability from year to year, the overall sediment production and infiltration did not increase when doubling the stocking rate, as long as biomass production increased to maintain similar range condition. Microtopography or roughness was not different between treatments.
