Factors Influencing Illinois Farmland Values
January 1, 2006By Haixiao Huang
A hedonic model of Illinois farmland values is estimated using county-level cross-section time-series
data. Explanatory variables include land productivity, parcel size, improvements, distances to...
Isolation of Salmonella bacteriophages from swine effluent lagoons
January 1, 2006By M.R. McLaughlin United States Department of Agriculture
Bacteriophages (phages) associated with Salmonella were collected from nine swine manure lagoons in Mississippi. Phages were isolated by an enrichment protocol or directly from effluent. For...
Characteristics of solids, BOD5 and VFAs in liquid swine manure treated by short-term low-intensity aeration for long-term storage
January 1, 2006By JUN ZHU
A laboratory-scale experiment presents data that reveal the temporal characteristics of solids, biochemical oxygen demand (BOD5) and volatile fatty acids (VFAs) in the aerated liquid swine manure for...
Ammonia recovery from swine belt separated liquid
January 1, 2006By Sarah K. Liehr
An evaluation of the feasibility of ammonia stripping for ammonia recovery from waste liquid resulting from an in-house belt separation system is presented. The liquid stream produced is a ...
Ammonia and nitrous oxide emissions from two acidic soils of Nova Scotia fertilised with liquid hog manure mixed with or without dicyandiamide
January 1, 2006By M.S. Mkhabela Department of Engineering
Gaseous nitrogen (N) loss from field-applied manure in the form of ammonia (NH3) and nitrous oxide (N2O) has negative agronomic, environmental and health implications. This study was undertaken to...
Bioleaching of zinc and copper from anaerobically digested swine manure: Effect of sulfur levels and solids contents
January 1, 2006By Shihwu Sung
Anaerobically digested swine manure (ADSM) generally contains high concentrations of zinc (Zn) and copper (Cu). These metals levels exceed the land application regulations of municipal biosolids of...
Influence of tillage and liquid swine manure on productivity of a soybean-barley rotation and some properties of a fine sandy loam in Prince Edward Island
January 1, 2006By Carter MR
Interactions between tillage management for manure incorporation and rate of manure application may influence crop productivity and soil properties. This study was conducted to evaluate the effect of...
