Surface Irrigation of Dairy Farm Effluent, Part I: Nutrient and Bacterial Load
When handled separately from manures, dairy farm effluents (DE) are costly to manage because of their low nutrient content and large volume. In anticipation of using surface irrigation to lower the land application cost of DE, this projects investigated the impact, on DE characteristics, of different sources and storage systems. Milk house wastewaters were monitored on two farms using a 500 l m...
متن کاملDairy farm effluent effects on urine patch nitrous oxide and carbon dioxide emissions.
Dairy farm effluent (DFE) comprises animal feces, urine, and wash-down water collected at the milking shed. This is collected daily during the milking season and sprayed onto grazed dairy pastures. Urine patches in grazed pastures make a significant contribution to anthropogenic N(2)O emissions. The DFE could potentially mitigate N(2)O emissions by influencing the N(2)O to dinitrogen (N(2)) rat...
متن کاملDairy farm cost efficiency.
A stochastic cost equation was estimated for US dairy farms using national data from the production year 2000 to determine how farmers might reduce their cost of production. Cost of producing a unit of milk was estimated into separate frontier (efficient) and inefficiency components, with both components estimated as a function of management and causation variables. Variables were entered as im...

Raised public expectation and increasing politicalpressure, in the face of mounting evidence thatsubstantial numbers of on-site wastewater disposalsystems perform poorly or fail, has resulted in therevision of State Government Guidelines and theAustralian Standard 1547. These revised guidelinesrequire a wider range of skills of Environmental HealthOfficers and others...
متن کاملCharacterization of effluent from an inland, low- salinity shrimp farm: what contribution could this water make if used for irrigation
Coastal aquaculture can contribute to eutrophication of receiving waters. New technologies and improved management practices allow the aquaculture industry to be more sustainable and economically viable. Current practices, however, do not provide an additional use for effluent water. Nitrogen, phosphorus and other effluent compounds could be valuable plant nutrients. Inflow and effluent water f...
