Ammonia (NH 3 ) volatilization from NH -based fertilizer and animal manure reduces their nitrogen (N) value is a source of environmental pollution. Mixing with biochar may lower by adding H + , adsorbing mineral N, or increasing N immobilization in microbial biomass. The objective this study was to determine whether wood-based could vented pails containing (liquid swine, dairy slurry, solid pou...

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...

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...

Technical Bulletin 1 ı As the poultry industry has grown, so have concerns about environmental management aspects, including air and water quality. There is a growing concern related to ammonia emission from poultry operations. Ammonia is a colorless, lighter than air, highly water-soluble gas present in the atmosphere of every poultry house. Ammonia volatilization from poultry litter commonly ...

This is a review paper on the effects of aluminum sulfate (alum) on ammonia volatilization and P runoff from poultry litter. Initially, laboratory studies were conducted that showed P solubility could be reduced in poultry litter with Al, Ca, and Fe amendments, indicating that these amendments may reduce P runoff. These results were confirmed in small plot studies in which alum applications to ...

Ammonia volatilization causes major nitrogen losses from the soil and applied urea which results in low urea-N usage efficiency. In line to this, laboratory incubation experiment was conducted assess effect of rice straw husk biochar on ammonia volatilization, pH, exchangeable ammonium, available nitrate comparison without additives under waterlogged conditions. Application mixture biochars at ...
