Measurement and control of greenhouse gas emissions from beef cattle feedlots
(2013-05-01)
Emission of greenhouse gases (GHGs), including nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from open beef cattle feedlots is becoming an environmental concern; however, scientific information on emissions ...
Seasonal effects on ammonia, nitrous oxide, and methane emissions for beef cattle excreta and urea fertilizer applied to a tropical pasture
(2019-11-01)
In this study we conducted four field trials (two wet- and two dry-season) to quantify N2O and CH4 emissions, NH3 volatilization, and N2O emission factors (EF3PRP) following the application of cattle dung, urine, dung plus ...
Gross, background, and net anthropogenic soil nitrous oxide emissions from soybean, corn, and wheat croplands
(American Society of Agronomy, 2019-01)
Agricultural soils are the largest single source of N2O emissions globally. However, soils left uncultivated would still release N2O. Distinguishing anthropogenic from natural emissions (i.e., background emissions) in crops ...
N2O emissions from urine-treated tropical soil: Effects of soil moisture and compaction, urine composition, and dung addition
(2017-10-01)
Increasing attention is being paid to the importance of N2O emissions due to livestock activities in tropical countries. Understanding the key variables driving N2O emission could help minimize impacts of N2O release and ...
Hierarchy of factors driving N2O emissions in non-tilled soils under different crops
(Wiley, 2013-08)
Nitrous oxide (N2O) is emitted to the atmosphere as a by-product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
Greenhouse gases emissions from tropical grasslands affected by nitrogen fertilizer management
(2020-11-01)
Greenhouse gases (GHGs) emissions from livestock systems are important because of their significant contribution to global warming. Nitrogen fertilization can improve system production; however, it alters soil gas emissions. ...
Increases in nitrogen use efficiency decrease nitrous oxide emissions but can penalize yield in sugarcane
(Springer Verlag Berlín, 2021-11-30)
Nitrogen (N) fertilization strategies focused on increasing nitrogen use efficiency (NUE) and decreasing nitrous oxide (N2O) emissions are important for sustainable crop production. In sugarcane, however, a joint assessment ...
The effect of moisture on nitrous oxide emissions from soil and the N 2O/(N2O+N2) ratio under laboratory conditions
(Springer, 2007-08)
Nitrous oxide (N2O) contributes to greenhouse effect; however, little information on the consequences of different moisture levels on N 2O/(N2O+N2) ratio is available. The aim of this work was to analyze the influence of ...
