Technical Abstract: An organic waste product was studied to determine its usefulness as a soil amendment without prerequisite composting. Previous results indicated numerous potential benefits in establishing native prairie grasses when applying this material to degraded training lands with loamy soils at rates up to 35.8 Mg/ha, so rates were quadrupled in the present study. The current study is located on a relatively productive sandy soil and a severely disturbed and barren soil at Fort Benning, GA. Vegetative cover, species composition, biomass, and plant chemical properties were analyzed for two growing seasons. Changes in biomass, basal vegetative cover, and nutrient acquisition were significantly affected by treatment rate, with the planted prairie grasses comprising the bulk of vegetation. The highly disturbed site suffered from a severe iron toxicity problem that was alleviated with high application rates of the organic material. Results from the land application studies of this material indicate that significant benefits can be achieved when applying sizeable quantities of it to degraded soils.
