Biochar: Agronomic and environmental potential in Brazilian savannah soils AGRIAMBI
Petter,Fabiano A.; Madari,Beata E..
Due to the high activity of microorganisms, the loss of soil organic matter is high in tropical regions. This loss becomes even greater if the soil is managed improperly or when there is no technology that leverages the permanence of the soil carbon by maintaining appropriate levels of organic matter, providing chemical, physical and biological soil improvements and contributing to reduce CO2 emissions to the atmosphere. Due to its aromatic structure, biochar is a highly stable form of carbon in the soil that may contribute to the reduction of greenhouse gas emissions, such as CO2, N2O and CH4, and act as a soil conditioner, improving the physical and chemical properties of the soil. Biochar may also result in increased productivity due to the improvement...

Biogeochemical diversity, O2-supersaturation and hot moments of GHG emissions from shallow alkaline lakes in the Pantanal of Nhecolândia, Brazil. Repositório Alice
BARBIERO, L.; SIQUEIRA NETO, M.; BRAZ, R. R.; CARMO, J. B. do; REZENDE FILHO, A. T.; MAZZI, E.; FERNANDES, F. A.; DAMATTO, S. R.; CAMARGO, P. B. de.
Nhecolândia is a vast sub-region of the Pantanal wetland in Brazilwith great diversity in surface water chemistry evolving in a sodic alkaline pathway under the influence of evaporation. In this region, N15,000 shallowlakes are likely to contribute an enormous quantity of greenhouse gas to the atmosphere, but the diversity of the biogeochemical scenarios and their variability in time and space is a major challenge to estimate the regional contribution. From4 selected alkaline lakes, we compiled measurements of the physico-chemical characteristics ofwater and sediments, gas fluxes in floating chambers, and sedimentation rates to illustrate this diversity. Although these lakes have a similar chemical composition, the results confirm a difference between the...

ความเป็นไปได้ของการใช้สารปรับปรุงดินเพื่อลดก๊าซเรือนกระจกและขณะเดียวกันรักษาผลผลิตข้าว: รายงานการวิจัยฉบับสมบูรณ์ Thai Agricultural
Patcharee Saenjan; Daungsamorn Tulapithak; Kasuyuki Inbuchi.
Field experiment was conducted in farmer’s rice field with loamy soil in Khon Kaen province, northeast of Thailand during to study the effect of different levels of sulfate (SO42-) on methane emission and rice yield. SO42- was applied at the rate of 0, 50, 100, and 210 kg SO42- ha-1 by using ammonium phosphate (42% SO42-) with balanced amount of 80 kg N, 100 kg P2O5 and 80 kg K2O ha-1 by adding various fertilizers. The experiment was laid out in randomized completely block design (RCBD) with tripled replication. CH4 flux was measured every week by using closed chambers method. Global warming potential (GWP) was also calculated. Soil samples were collage at each growth stage to determine SO42-, NH4+ and Fe2+. Rice yield was measured at harvest. The...

Effect of water management to emission methane gas in Lopburi Rice Research Center dry season in 2014. Under Development of Alternative Technologies for Greenhouse Gas Emission Reduction and Information System for Decision Support of Policy Maker Project was experimental by Randomized Complete Block (RCB) 3 Replications to compare greenhouse gas emission from 3 Alternative Wet and Dry (AWD) with -10, -15, -20 cm water level and continuous irrigation method. Results showed that Lopburi Rice Research Center was sandy loam soil and AWD irrigation with -10 to -20 cm water level was 27 – 31 % water saving with comparative continuous irrigation method. AWD irrigation with -15 cm water level drainage tended to be best practice with minimum emission and water...
