Conservation Agriculture With Optimum Fertilizer Nitrogen Rate Reduces GWP for Rice Cultivation in Floodplain Soils

چکیده
Wetland rice cultivation contributes significantly to global warming potential (GWP), an effect which is largely attributed emissions of methane (CH 4 ). Emerging technologies for wetland production such as conservation agriculture (CA) may mitigate greenhouse gas (GHG) emissions, but the effects are not well defined. Investigations were carried out in irrigated (Boro rice) field fifth crop after conversion conventional tillage (CT) strip (ST). Two residue levels (low versus high, LR HR) and three nitrogen (N) application rates (N1 = 108, N2 144, N3 180 kg N ha −1 ) laid a split-plot experiment with replicates. Yield-scaled GHG GWP estimated evaluate impacts CA on mitigating CH 2 O paddy field. There was 55% higher emission ST HR coupled than that CT N1. The factors ranged from 0.43 0.75% 0.45 0.59% CT, irrespective level rate. By contrast, lower practices (CT plus LR). reduced by 39% over N1 16% practices. Based our investigation combination tillage, residue, rate treatments, adoption high low 10 16%, respectively, because current management relatively suggest mitigation this systems needs greater attention.

The increase of nitrite and nitrate concentrations in surface and groundwater is a greatconcern in our lives nowadays. Nitrate and nitrite in drinking water normally originate fromagricultural operation and chemical fertilizers. Therefore, the present study aims toinvestigate the effect of nitrogen fertilizers used in rice cultivation and levels of nitrate andnitrite in farm wastewater and wate...
متن کاملNitrogen Fertilizer Losses from Rice Soils and Control of Environmental Pollution Problems
Nitrogen (N) requirements of rice crop are met from both the soil and fertilizers. Because of acute N deficiency in most rice soils, fertilizer N must be applied to meet the crop demand. N fertilizer applied to rice crops is partially lost through different mechanisms, including ammonia volatilization, denitrification, and leaching. These losses may cause environmental problems such as pollutin...

The impact of management on global warming potential (GWP), crop production, and greenhouse gas intensity (GHGI) in irrigated agriculture is not well documented. A no-till (NT) cropping systems study initiated in 1999 to evaluate soil organic carbon (SOC) sequestration potential in irrigated agriculture was used in this study to make trace gas flux measurements for 3 yr to facilitate a complete...

Regional Approach to Making Nitrogen Fertilizer Rate Decisions for Corn
Nitrogen fertilizer is one of the largest input costs for growing corn. Across the Corn Belt, N is typically the most yield-limiting nutrient. Facing record high N fertilizer prices and potential supply problems, producers are concerned about N fertilization rates. Soil fertility researchers and extension specialists from seven states across the Corn Belt (see list in acknowledgements section) ...
