“…The influence of soil water content on N 2 O and NO x emissions has been illustrated in several intances: water logging increases N 2 O-N losses to approximately 1% of the N added with sugar beet residues (Flessa and Beese, 1995); a very strong relationship between N 2 O emission and soil nitrate content was found for grassland, provided the water-filled pore space was higher than 70% (Smith et al, 1998b); nitrous oxide emission increases exponentially with increasing water-filled pore space in the soil (Smith et al, 1998a); nitrous oxide fluxes are substantial only when the soil water content is high (>27 g per 100 g) (Ball et al, 1999); under rain fed rice, large N 2 O fluxes are observed shortly after rainfall events due to denitrification of accumulated NO À 3 (Abao et al, 2000); under flooded soil conditions, nitrate resulting from nitrification quickly disappears due to denitrification, resulting in a very high loss of fertilizer N, up to 70% of N applied (Aulakh and Singh, 2001).…”

A review of the N 2 O-N emission from crop residues was conducted based on new data published during the last decade. The result indicated that factors as type of crop, biochemical quality of residues, agricultural management, climate and season of the year, soil properties and soil moisture play a significant role in the rate of N 2 O-N emissions. An emission factor (EF) equal to 1.055% of N applied in plant residues -derived from a simple linear regression of emitted N 2 O-N (kg ha )1 ) on N applied in crop residues (kg ha )1 ) -represent an estimate that explains about 60% of emission variations. However, the EF of N applied in plant residues is not a constant but a variable coefficient that depends on environmental and management variables. The following two linear models -that estimate emitted N 2 O-N (kg ha )1 ) as a function of the variables N (kg ha )1 ) applied in plant residues (NPR), rain (mm), temperature (°C) and temperature 2 (°C 2 ) -were fitted to the dataset with 45 observations obtained from the reviewed literature.

Because of its internal structure, the second model is more appealing as it represents N 2 O-N emission as a transformation that is affected by management and environmental variables. The following expression -that correspond to the quantities in the square bracket at the right hand side of the second model -is the coefficient for the variable N applied in crop residues, and represent the emission factor as a function of application method of plant residues, rain, temperature and temperature 2 .EF ¼ À0:0404 þ 0:0078 ApM þ 0:000044Rain þ 0:00567 Tem À 0:0001975 Tem 2 Standardization of research methodologies and data gathering and reporting, including kind of crop, N content of applied residues, agricultural management, length of the measuring period, climate, soils properties, soil temperature and water content, would facilitate further advances in studies oriented to increase the precision of N 2 O-N emission estimates.

A field experiment was conducted in Bangladesh Agricultural University Farm to investigate the mitigating effects of soil amendments such as calcium carbide, calcium silicate, phosphogypsum, and biochar with urea fertilizer on global warming potentials (GWPs) of methane (CH 4 ) and nitrous oxide (N 2 O) gases during rice cultivation under continuous and intermittent irrigations. Among the amendments phosphogypsum and silicate fertilizer, being potential source of electron acceptors, decreased maximum level of seasonal CH 4 flux by 25-27 % and 32-38 % in continuous and intermittent irrigations, respectively. Biochar and calcium carbide amendments, acting as nitrification inhibitors, decreased N 2 O emissions by 36-40 % and 26-30 % under continuous and intermittent irrigations, respectively. The total GWP of CH 4 and N 2 O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively. However, biochar amendments increased overall GWP of CH 4 and N 2 O gases.

Calcium carbide, a stable solid compound composed of two atoms of carbon and one of calcium, has proven its effectiveness in chemical synthesis, due to the safety and convenience of handling the C≡C acetylenic units. The areas of CaC2 application are very diverse, and the development of calcium‐mediated approaches resolves several important challenges. This Review aims to discuss the laboratory chemistry of calcium carbide, and to go beyond its frontiers to organic synthesis, life sciences, materials and construction, carbon dioxide capturing, alloy manufacturing, and agriculture. The recyclability of calcium carbide and the availability of large‐scale industrial production facilities, as well as the future possibility of fossil‐resource‐independent manufacturing, position this compound as a key chemical platform for sustainable development. Easy regeneration and reuse of the carbide highlight calcium‐based sustainable chemical technologies as promising instruments for total carbon recycling.
