Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate (alum) and aluminum chloride applications to swine manure on P runoff from small plots cropped to tall fescue (Festuca arundinacea Shreb.). There were six treatments in this study: (i) unfertilized con...

OBJECTIVES Liquid manure systems and manure pits are major hazards in the agricultural workplace. The incidence of accidents related to manure is unknown. The objective of this study was to survey the liquid manure facilities of farms in eastern Switzerland and find the incidence of accidents related to manure in the region. METHODS Retrospective cohort study and cross sectional survey of 210...

Introduction ield experience and research demonstrate that manure nutrients can be readily substituted for commercial fertilizer. Fertilizer needs depend on soil test levels. Substituting manure at a lower cost than commercial fertilizer can result in signifi cant savings if relatively uniform application and distribution can be maintained. The less nutrient-dense manure requires more hauling o...

BACKGROUND Clostridium chauvoei causes blackleg, an acute disease associated with high mortality in ruminants. The apparent primary port of entry is oral, during grazing on pasture contaminated by spores. Cases of blackleg can occur year after year on contaminated pastures. A method to determine the prevalence of C. chauvoei spores on pasture would be useful.The standard method for C. chauvoei ...

of factors that make manure an undependable source of plant nutrients, including differences in soil fertility Estimates of the availability of dairy manure nutrients to crops levels where manure application experiments have been rely on indirect measurements and can vary greatly. More accurate estimates of manure nutrient availability are needed to improve maconducted, inherent shortcomings of...

Attachment of bacteria to soil is an important component of bacterial fate and transport. Escherichia coli are commonly used as indicators of fecal contamination in the environment. Despite the fact that E. coli are derived exclusively from feces or manure, effect of the presence of manure colloids on bacteria attachment to agricultural soils was never directly studied. The objective of this wo...

Introduction Manure odor is the result of the anaerobic decomposition of the organic matter present. By altering the composition of manure, as excreted, changes in the odor of decomposing manure may occur. Compositional alteration may occur by changing the dietary nutrient composition or by altering the use of these nutrients. Feed ingredients may contribute to manure odor due to their nutritio...

Historically, manure has been recognized as an excellent soil amendment that can improve soil quality and provide nutrients for crop production. In areas of high animal density, however, the potential for water pollution resulting from improper storage or disposal of manure may be significant. The objective of this study was to determine the P balance of cultivated soils under barley (Hordeum v...

Many states have passed legislation that regulates agricultural P applications based on soil P levels and crop P uptake in an attempt to protect surface waters from nonpoint P inputs. Phytase enzyme and high available phosphorus (HAP) corn supplements to poultry feed are considered potential remedies to this problem because they can reduce total P concentrations in manure. However, less is know...

Manure in an inevitable byproduct of the production of meat and milk destined for human consumption. Excessive excretion of manure and manure nutrients represent inefficiencies which increase feed costs, increase the environmental impact of dairy farming, and increase the costs associated with moving and storing manure. Profitability can be enhanced when good feeding and management practices ar...
