"Land Applied Biosolids Restore Disturbed Rangelands"

From BioCycle, Sept. 2007 - click on PDF Full Text for complete article

The article examines the potential of land applying aerobically digested biosolids to improve the forage and soil quality at disturbed rangelands in the U.S. The author explains that treated municipal sewage sludge or biosolids is a valuable and inexhaustible resource for restoring the vigor of disturbed rangelands. He further claims that biosolids represent a low cost source of organic matter as well as provide buffering capacity when land applied. Moreover, biosolids land application on arid or semi-arid rangelands poses little threat to groundwater resources in areas with adequate groundwater depths.
