Research Project: Nutrient Status and Runoff Potential from Animal Manures after Anaerobic Digestion

Location: 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.


3.Progress Report:

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.
