Composting Bedded Pack Manure Reduces Runoff Losses
A research brief posted by the Center for Integrated Agricultural Systems at the University of Wisconsin says that composting dairy manure and bedding pack before spreading it on fields reduces runoff losses. Composting Manure and Bedding Reduces Potential Soil and Phosphorus Loss shows that composting is a viable way to reduce phosphorus runoff losses from livestock operations with bedded pack manure. A composting step eliminates the need to spread manure on frozen ground, and it both reduces the water solubility of phosphorus and adds stable organic matter that results in reduced erosion.
