Rangeland Restoration Using Biosolids Land Application
Abstract:Land application of aerobically digested biosolids, anaerobically digested biosolids and beef cattle manure as an approach to restore disturbed rangelands was evaluated. While control plots yielded, on average, 84.1 lbs/acre of forage dry matter, dry forage yield on rangeland plots receiving aerobically digested biosolids, anaerobically digested biosolids and beef cattle manure ranged from 129.0 to 664.1 lbs/acre. Field tests indicated an average moisture infiltration rate of 7.07 cm/hr for control plots compared to a maximum of 7.14, 9.98 and 9.56 cm/hr in plots receiving aerobically digested, anaerobically digested and beef cattle manure, respectively. The increase in forage yield and moisture infiltration underscored the value of biosolids land application in rangeland restoration activities.
