For the ammonia generated in Korea, contribution rate of livestock manure is high, and a large amount (NH3) emitted into atmosphere during soil application process. Volatilization NH3 affected by characteristics as well characteristics, but current inventory does not sufficiently reflect this. This study was conducted to confirm change from liquid fertilizer (LF) due pH evaluate impacts biochar...

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...

Ammonia (NH3) volatilization from poultry litter results in a buildup of atmospheric NH3 in chicken houses, which is detrimental to both farm laborers and birds. Ammonia loss from litter is detrimental to the external environment because it results in acid rain, as well as low N/P ratios in litter, which increase the likelihood of excessive P runoff into adjacent water bodies. The objectives of...

Animal supplementation during the background phase may increase greenhouse gas emissions (GHG). The inclusion of tannins in diet Nellore bulls can mitigate nitrous oxide (N2O), methane (CH4), and ammonia (NH3) production. objective this study was to quantify effect energy associated with sources young backgrounded pastures N2O, CH4, NH3 emissions. Two experiments were conducted a completely ran...

The threat of odors emitted from pork production operations in some areas of the country has restricted growth of the industry and has created negative relations with residential neighbors. Odors from manure result from microbial decomposition of the organic matter and nutrients in undigested feed, and normal exogenous end products of cellular metabolism. Reducing nutrient excretions and contro...

This study evaluated the effect of feeding silage to pigs on nitrogen (N) utilization and ammonia (NH3) volatilization. In total, 128 Yorkshire × Hampshire (30–110 kg) were fed commercial feed (Control) or mixed with dried, milled in pelleted form (Pellet-S), fresh, chopped (Silage-Ch) intensively treated (Silage-Pr). Silage replaced 20% crude protein (g/kg). Diet affected daily N excretion, wh...

Novel fertilizer stabilization technologies are needed to decrease ammonia (NH3-N) losses and increase nitrogen use efficiency. Duromide + NBPT is a new technology that combines two molecules, NBPT, whose propose the efficiency of urease inhibitor in reducing NH3-N loss from urea. Preliminary results showed can be more effective product than just particularly under low soil pH high-temperature ...

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...
