Soil Tillage Conservation and its Effect on Erosion Control, Water Management and Carbon Sequestration

Moraru Paula Ioana, T. Rusu, Mara Lucia Sopterean

Abstract


Nowadays, internationally is unanimous accepted the fact that global climatic changes are the results of human intervention in the bio-geo-chemical water and material cycle, and the sequestration of carbon in soil is considered an important intervention to limit these changes. Carbon sequestration in soil is net advantageous, improving the productivity and sustainability. The more the organic content in soil is higher the better soil aggregation is. The soil without 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 through water and wind. Presently a change it is necessary concerning the concept of conservation practices and a new approach regarding the control of erosion. The real conservation of soil must be expanded beyond the traditional understanding of soil erosion. The real soil conservation is represented by carbon management. We need to focus to another level concerning conservation by focusing on the soil quality. Carbon management is necessary for a complex of matters including soil, water management, field productivity, biological fuel and climatic change. Profound research is necessary in order to establish the carbon sequestration practices and their implementation impact. Soil oxygen and carbon dioxide concentration dynamics can be continuously monitored in the present using new generation of sensors available. Systems for soil gas measurements offer crucial information regarding production, consume, and transport of gas, with major implications in quantitative and qualitative evaluation of soil respiration and soil aeration.
