Laying the Groundwork for Odor Control and Setback Estimation in Nebraska
January 1, 2005By Richard R. Stowell
The goal of this field research study was to validate use of the Odor Footprint Tool (OFT) with livestock building sources in rural communities. The primary objective was to evaluate the accuracy of...
Evaluation of electrolysis for oxidative deodorization of hog manure
January 1, 2005By Bunce|N.J.
Electrolysis was investigated as a method for the amelioration of odor from the supernatant phase of centrifuged liquid hog manure. Methods examined included the use of dual anodes to provide both...

Water intake and wastage at nipple drinkers by growing-finishing pigs
January 1, 2005By Y. Z. Li
Three experiments were conducted to assess water intake, water wastage, and a means to decrease water wastage by growing-finishing pigs from nipple drinkers. In Exp. 1, 48 pigs were studied during ...
Preliminary investigation of air bubbling and dietary sulfur reduction to mitigate hydrogen sulfide and odor from swine waste
January 1, 2005By Grant Clark
When livestock manure slurry is agitated, the sudden release of hydrogen sulfide (H2S) can raise concentrations to dangerous levels. Low-level air bubbling and dietary S reduction were evaluated as...
Dissimilatory iron reduction and odor indicator abatement by biofilm communities in swine manure microcosms
January 1, 2005By Bruns|M.A
Animal waste odors arising from products of anaerobic microbial metabolism create community relations problems for livestock producers. We investigated a novel approach to swine waste odor reduction:...
PHOSPHORUS RUNOFF POTENTIAL OF VARYING SOURCES OF MANURE APPLIED TO FESCUE PASTURES IN VIRGINIA
January 1, 2005
The P Index for Virginia uses coefficients describing the risk of P runoff from pastures for different nutrient sources, but these coefficients have not been verified on Virginian soils. An...
Deodorization of swine manure using minced horseradish roots and peroxides
January 1, 2005By Jerzy Dec
Public concerns about offensive odors from livestock manures are on the rise and so is the pressure to develop practical ways to reduce the odors. The use of minced horseradish (Armoracia rusticana...
Management strategy impacts on ammonia volatilization from swine manure
January 1, 2005
Ammonia emitted from manure can have detrimental effects on health, environmental quality, and fertilizer value. The objective of this study was to measure the potential for reduction in ammonia...
Demonstrating Innovative Use of Precision Farming Technologies to Optimize Manure Nutrient Utilization and Reduce Environmental Concerns
January 1, 2005By Dr. Richard Wolkowski
The uniform application of manure is difficult and often leads to questions of available nutrient credits. For these reasons farmers and their consultants often discount the value of these nutrients...
Field-scale evaluation of phosphorus leaching in acid sandy soils receiving swine waste
January 1, 2005By Nathan O. Nelson
Accurate descriptions of P leaching are important because excess P applied to soils can enter surface water via leaching and subsurface transport, thereby negatively impacting water quality. The...
