Increased nitrogen (N) deposition is common worldwide. Questions of where, how, and if reactive N-input influences soil carbon (C) sequestration in terrestrial ecosystems are of great concern. To explore the potential for soil C sequestration in steppe region under N and phosphorus (P) addition, we conducted a field experiment between 2006 and 2012 in the temperate grasslands of northern China....

A study was conducted to assess the effects of organic amendments on soil aggregates, carbon (C) sequestration, and energy use efficiency (EUE) during five consecutive Boro Transplanted Aman rice seasons in Bangladesh 2018–2020. Five treatments (viz., control (only inorganic fertilizers), cow dung (CD), vermicompost (VC), straw (RS), poultry manure (PM)) were used. The materials applied at 2 t ...

underground coal gasification (ucg) is a non-conventional method of extracting gas from coal. the primary advantage of ucg is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world’s coal reserves by an estimated 70%; for this reason, ucg has been implemented at sites around the world. however, the gaseous, liquid and solid waste streams which ac...

BACKGROUND Evaluating the net exchange of greenhouse gas (GHG) emissions in conjunction with soil carbon sequestration may give a comprehensive insight on the role of agricultural production in global warming. MATERIALS AND METHODS Measured data of methane (CH(4)) and nitrous oxide (N(2)O) were utilized to test the applicability of the Denitrification and Decomposition (DNDC) model to a winte...

Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...

Removing carbon dioxide (CO2) from the atmosphere and storing the carbon (C) in resistant soil organic matter (SOM) is a global priority to restore soil fertility and help mitigate climate change. Although it is widely assumed that retaining rather than removing or burning crop residues will increase SOM levels, many studies have failed to demonstrate this. We hypothesised that the microbial na...

Owing to the methane (CH4) produced by rumen fermentation, ruminants are a source of greenhouse gas (GHG) and are perceived as a problem. We propose that with appropriate regenerative crop and grazing management, ruminants not only reduce overall GHG emissions, but also facilitate provision of essential ecosystem services, increase soil carbon (C) sequestration, and reduce environmental damage....

Promoting cropland carbon (C) sequestration through straw return has always been the focus of numerous studies. However, there is still a lack comprehensive understanding effects on soil organic (SOC) and inorganic (SIC) sequestration. Therefore, present study aims to investigate long-term SOC SIC across 0–100 cm profile in maize planting Northeastern China. The results showed an increasing tre...

Our goal is to measure carbon balance of our southern California desert ecosystems, with a particular focus on teasing apart weathering of inorganic C and mineralization of organic C, versus sequestration by native desert communities in the face of soil and vegetation disturbances to place solar electricitygenerating projects. We will: 1) develop techniques to assess caliche layering and amount...

ongoing climate change has been a major global challenge since the 1880s. sequestration of carbon(c) in rangelands ecosystems could provide a net carbon sink to offset increases in atmospheric c in global scale. this research is aimed at estimating the above-ground biomass carbon sequestration potential in iran. for this purpose, total rangelands area and productivity data were extracted from t...
