Estimating Ammonia Volatilization from Swine-Effluent Droplets in Sprinkle Irrigation
homa State University Research Station in Goodwell, OK to measure volatilization losses of ammoniacal N Irrigation of swine effluent is one of the most economical ways to from swine-effluent applied to the land surface by flood dispose of swine manure. The determination of appropriate application rates requires the quantification of volatilization losses of ammoirrigation. Wu et al. (2003) deve...
متن کاملManagement strategy impacts on ammonia volatilization from swine manure.
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 volatilization from swine (Sus scrofa domestica) manure by temperature control, stirring, addition of nitrogen binder (Mohave yucca, Yucca schidigera Roezl ex Ortgies) or urease inhibitor [N-(n-butyl) t...
متن کاملAmmonia Volatilization from Constructed Wetlands That Treat Swine Wastewater
Increasingly, large–scale animal production occurs in confinement where large per–unit–area quantities of waste are generated. With the increased scale of production, new environment–friendly technologies are needed to deal with the waste. Constructed wetlands are considered an alternative treatment, but it is not known if volatilization of free ammonia (NH3) governs nitrogen removal in these s...
متن کاملEffect of adding alum or zeolite to dairy slurry on ammonia volatilization and chemical composition.
Development of cost-effective amendments for treating dairy slurry has become a critical problem as the number of cows on farms continues to grow and the acreage available for manure spreading continues to shrink. To determine effectiveness and optimal rates of addition of either alum or zeolite to dairy slurry, we measured ammonia emissions and resulting chemical changes in the slurry in respo...
متن کاملAmmonia volatilization from arable land after application of catt'e slurry. 1. Field estimates
Cattle slurry was surface-applied to bare soil in two experiments in the period September November 1987, while in April-May 1988 two experiments were carried out in which the slur ry was mixed with the upper 6 an of the soil with a cultivator immediately after spreading. The 1987 experiments both lasted 18 days, the 1988 experiments 9 days. A micrometcorologi· cal technique, which did not dis...
