Management of soil pH promotes nitrous oxide reduction and thus mitigates soil emissions of this greenhouse gas

UK emissions of the greenhouse gas nitrous oxide.

Signatories of the Kyoto Protocol are obliged to submit annual accounts of their anthropogenic greenhouse gas emissions, which include nitrous oxide (N(2)O). Emissions from the sectors industry (3.8 Gg), energy (14.4 Gg), agriculture (86.8 Gg), wastewater (4.4 Gg), land use, land-use change and forestry (2.1 Gg) can be calculated by multiplying activity data (i.e. amount of fertilizer applied, ...

Biochar Impacts on Soil Physical Properties and Greenhouse Gas Emissions

Biochar, a co-product of a controlled pyrolysis process, can be used as a tool for sequestering C in soil to offset greenhouse gas (GHG) emissions, and as a soil amendment. Whereas the impacts of biochar application on soil chemical properties are widely known, the research information on soil physical properties is scarce. The objectives of this review are to (i) synthesize available data on s...

Management of Native Soil Nitrogen for Reducing Nitrous Oxide Emissions and Higher Rice Production

Present production of rice is far below its reported potential yield because of being Ndeficiency, the major constraint. Because of poverty, small farmers have to rely on native soil N-supply. Between wheat harvest and rice transplanting, a dry-to-wet season transition (DWT) period exist with changing soil moisture from aerobic to anaerobic and a large amount of native soil N loss is hypothesiz...

The potential of responsible peatland management to reduce global soil carbon loss and greenhouse gas emissions

Peatlands represent the largest single global store of soil carbon. Despite providing a natural long-term CO2 sink, drainage and conversion to agricultural and silivicultural management of peatlands has converted them into large net contributors to global greenhouse gas (GHG) emissions (~2.5% of all anthropogenic emissions, primarily from Europe and SE Asia). Drainage-based agriculture on peatl...
