Anaerobic swine lagoon sludge sampling allows operators to determine the nutrient concentration in the sludge through laboratory analysis. This publication provides information about different options for sampling sludge in these lagoons.
This publication addresses nutrient management concerns as they relate to land application of animal wastes, municipal biosolids, industrial residuals and agricultural by-products, with a focus on phosphorus application and its impact on the environment. Methods for reducing phosphorus loss from land application sites are presented as general guidance for managers of land application systems, who must be knowledgeable of regulatory issues and permit restrictions as they relate to phosphorus and nutrient management.
