Review on: The Role of Improving Soil Carbon Sequestration to Mitigate Global Climatic Change and Optimize Biogeochemical Cycle of Carbon

Dejene Matiyas


The current climatic change issue be coming vital concerns of every sector as far as it related to the efficiency and wellbeing of every sectors globally. Mean annual max and min temperature of Earth’s becomes harsh for life on it due to various effects on greenhouse gases concentration triggered from natural and anthropic causes. Soil can be mentioned as a major contributor both as a source and/or sink to manipulate the atmospheric greenhouse gas concentration. Agricultural soil management practice should be considered as a tool to maximize the drawdown of carbon from atmosphere. Soil Carbone sequestration can be optimized through different land management practices which can enhance soil carbon sequestration through increasing the rates of organic matter input, partitioning carbon to longer-lived pools, increasing the longevity of all or selected carbon pools. Different methods of agricultural management use one or more of these pathways to enhance carbon sequestration. Maintaining soil pH at neutral or higher levels also enhance chemical stability in the form of biochemical recalcitrance, physicochemical protection, or both which increases the rate of humic compound formation and decreases the rate of mineralization, resulting in increased soil organic carbon. Conservation practices and money more others agricultural practices which minimize the Carbone emission from the soil and even trapping the atmospheric Carbone and change it to soil Carbone pool as chelates were contribute significant role in global climatic change mitigation efforts.

Keywords:  Greenhouse gas, atmosphere, soil, carbon sequestration, humic compound.
