Title: Nutrient Movement and Removal in a Switchgrass Biomass–Filter Strip System Treated with Dairy Manure

Authors: Matt A. Sanderson, Ronald M. Jones, Marshall J. McFarland, Jason Stroup, Roderick L. Reed and James P. Muir

Summary: The effectiveness of switchgrass filter strips to remove nutrients from dairy effluent and solid manure was assessed.
Five rates of solid dairy manure and lagoon effluent were applied to field plots of swichgrass with a 5.2 by 16.5 meter filter strip below the application area. Total reactive P concentrations were reduced by 47% for the 150 kg N rate and 76% for the 600 kg N rate in 1996 and 1997. Soil water collected at 46 or 91 cm below the soil surface contained less than 3 mg L-1 of nitrate nitrogen in all plots
