Abstract:

Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols. Thus, we conducted the research based on 14 years (1999–2013) of long-term fertilization experiment with a no fertilizer control, 50% NPK, 100% NPK, 150% NPK, 100% NPK+Zn, 100% NP, 100% N, 100% NPK+FYM, 50% NPK+BGA and 50% NPK+GM. Mean SOC sequestration rate was 0.812 ton/ha/yr in 150% NPK treatment and 0.206, 0.13, -0.662, -0.821, -1.025, -1.082, -1.724, -2.817 and -3.302 t/ha/yr in 100% NPK, 100% NPK+FYM, 50% NPK+GM, 50% NPK, 100% NPK+Zn, 50% NPK+BGA, 100% NP, 100%N and Control respectively. The Change in Nutrient balances higher values were recorded in inorganic treatments compare to the organic treatments due to increasing rates of fertilizer application increased nutrient balance.
