Dairy farm effluent effects on urine patch nitrous oxide and carbon dioxide emissions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
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 ...
Dissolved organic nitrogen : an overlooked pathway of nitrogen loss from agricultural systems?
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2009)
Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO₃⁻. Although the export of dissolved organic nitrogen (DON) into the
groundwater has been recognized for more than 100 ...
Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal in highly contaminated field soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2007)
This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage ...
Ammonia, methane, and nitrous oxide emission from pig slurry applied to a pasture in New Zealand
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Much animal manure is being applied to small land areas close to animal confinements, resulting in environmental degradation. This paper reports a study on the emissions of ammonia (NH₃), methane (CH₄), and nitrous oxide ...
