Nutrient Status and Runoff Potential from Animal Manures after Anaerobic Digestion
National Soil Erosion Research Lab
2013 Annual Report
1a.Objectives (from AD-416):
Synthesis of the nutrient recovery from anaerobic digestion of animal manures and evaluation of nutrient runoff potential from land application of digester effluents.
1b.Approach (from AD-416):
Compilation of existing information regarding to nutrient recovery from anaerobic digesters; quantify the nutrient status and improve the digestion process to maximize nutrient recovery; using rainfall simulation to quantify nutrient runoff potential from land application of digester effluents.
The Quality Assurance Protection Plan has been written for this project, and rainfall simulations for anaerobic digester influent/effluent were conducted on plots cropped to corn.
