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 ...
Microorganisms in sewage sludge added to an extreme alkaline saline soil affect carbon and nitrogen dynamics
(2012-11-27)
There are plans to vegetate soil of the former lake Texcoco and use wastewater sludge to provide nutrients.
However, the Texcoco soil is N depleted, so the amount of N available to the vegetation might be
limited and the ...
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 ...
Contrasting Effects of Nitrogen and Labile Carbon Addition on N2O Emissions from Andosols in Costa Rica and Chile Under Controlled Conditions
(2022-07-20)
Our study analyzes nitrous oxide (N2O) emissions of two volcanic soils, from a tropical (Costa Rica) and temperate (Chile) environment. Volcanic origin soils are important for dairy production in both countries and ...
Soil Greenhouse Gases: Relations to Soil Attributes in a Sugarcane Production Area
(Soil Sci Soc Amer, 2017-09-01)
The production of the main soil greenhouse gases (GHG: carbon dioxide [CO2], methane [CH4,] and nitrous oxide [N2O]) is influenced by agricultural practices that cause changes in soil physical, chemical, and biological ...
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 ...
Are ch4, co2, and n2 o emissions from soil affected by the sources and doses of n in warm-season pasture?
(2021-06-01)
The intensification of pasture production has increased the use of N fertilizers—a practice that can alter soil greenhouse gas (GHG) fluxes. The objective of the present study was to evaluate the fluxes of CH4, CO2, and ...
Soil N2O emissions and N2O/(N2O+N 2) ratio as affected by different fertilization practices and soil moisture
(Springer, 2008-06-10)
The objective of this work was to evaluate the effect of the chemical nature and application frequency of N fertilizers at different moisture contents on soil N2O emissions and N2O/(N2O+N 2) ratio. The research was based ...
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 ...
