Soil Tillage Conservation and its Effect on Erosion Control, Water Management and Carbon SequestrationKeywords: soil tillage conservation , carbon sequestration , soil respiration , CO2 monitoring , CO2 flux , gradient method Abstract: Nowadays, internationally is unanimous accepted the fact that global climatic changes are the results of humanintervention in the bio-geo-chemical water and material cycle, and the sequestration of carbon in soil is considered animportant intervention to limit these changes. Carbon sequestration in soil is net advantageous, improving theproductivity and sustainability. The more the organic content in soil is higher the better soil aggregation is. The soilwithout organic content is compact. This reduces its capacity to infiltrate water, nutrients solubility and productivity,and that way it reduces the soil capacity for carbon sequestration. Also it raises soil vulnerability to erosion throughwater and wind. Presently a change it is necessary concerning the concept of conservation practices and a newapproach regarding the control of erosion. The real conservation of soil must be expanded beyond the traditionalunderstanding of soil erosion. The real soil conservation is represented by carbon management. We need to focus toanother level concerning conservation by focusing on the soil quality. Carbon management is necessary for a complexof matters including soil, water management, field productivity, biological fuel and climatic change. Profound researchis necessary in order to establish the carbon sequestration practices and their implementation impact. Soil oxygen andcarbon dioxide concentration dynamics can be continuously monitored in the present using new generation of sensorsavailable. Systems for soil gas measurements offer crucial information regarding production, consume, and transport ofgas, with major implications in quantitative and qualitative evaluation of soil respiration and soil aeration.
