Land application of biosolids to restore disturbed western rangelands

摘要：

Introduction Many rangelands in the western U.S.have been degraded through improper grazing.Biosolids are an inexhaustible resource that can be utilized to restore disturbed rangelands.Application of biosolids poses little threat to groundwater resources in areas with adequate groundwater depth because evapotranspiration generally exceeds total precipitation (Evans et al.,2001; Harris-Pierce et al.,1995).The current study compared effects of biosolids application to disturbed rangelands.
