23 Oct Emission of Greenhouse Gases From Agricultural Sources and Their Mitigation
कृषि स्रोतों से उत्सर्जित ग्रीनहाउस गैसों का शमन Word agriculture contributes about 4% to total carbon dioxide emission, the most important green house gas. Factor such as soil texture, temperature, moisture, PH, available C and N influence Co2 emission from soil. The rate of Co evaluation is greater from clay-loam soil, which has highest organic C content than sandy soil, more Co2 emission occurs from a tilled than from an undisturbed soil (no till) . Temperature has a marked effect on Co2 evolution from soil by influencing root and soil respiration and on CH4 by affecting anaerobic carbon mineralization and methanogenic activity. Methane is about 20 times more effective than co2 as a...
