Runoff and Erosion Following Field Application of Beef Cattle Manure and Compost

Manure or compost from beef cattle feedlots can be excellent sources of nutrients and organic matter whenadded to soils. This study was conducted to determine the effect of a single application of manure and compost on runoffand erosion under no-till and tillage conditions. Tillage consisted of a single disking operation up and down the slope ona Sharpsburg soil which was cropped to grain sorghum or wheat the previous season. Manure and compost were appliedat rates required to meet corn fertility requirements. Additional experimental treatments included the application ofinorganic fertilizer and an untreated check. The addition of manure or compost to the no-till plots containing sorghum orwheat residue resulted in significant reductions in residue cover. However, residue cover following tillage was unaffectedby the earlier addition of manure or compost. Runoff and erosion from simulated rainfall were not significantly influencedby the single application of manure or compost. On the no-till sorghum residue treatments, total solids transportrepresented 5.1% and 3.3% of the mass of applied manure and compost, respectively. Total solids transport was 1.3% and1.4% of the mass of applied manure and compost, respectively, on the no-till wheat residue treatments.
