2011 Annual Report
A laboratory experiment was conducted to evaluate nine manure bedding pack materials consisting of various crop residues and wood byproducts. Air quality emissions and manure characteristics were measured on the manure packs. A second experiment was initiated to look at combinations of different bedding pack materials.
ARS scientists evaluated two full-scale odor reduction technologies at tunnel-ventilated swine barns with a cooperator in another state. The first technology was an automated scraper system designed to replace the existing flush system. The second technology was a vegetative environmental buffer (VEB), which consisted of specially designed rows of trees and shrubs placed downwind of the exhaust fans in the tunnel-ventilated swine barns. Accurate estimation of air emissions from animal feeding operations is crucial for regulatory reporting and testing of abatement measures. ARS scientists developed methods for comparing emissions from different measurement devices. With support from a grant from the National Pork Board, methods for quantifying air emissions from the land application of swine manure and for assessing additives for odor control were evaluated.
As part of an NRI grant project, ARS scientists have initiated collaborative research with Iowa State University and the Kansas firm of Bio-Research Products Inc. to evaluate soybean-byproduct additives for reducing odor emissions from swine lagoons. A laboratory experiment was conducted to determine the optimum amount of additive necessary for odor control of swine manure.
A multi-year study was completed that evaluated the effectiveness of using coal-ash material as a pen surfacing material. The study determined the effect of coal-ash surfaced pens on the quality and quantity of manure collected.
