Conservation soil tillage and environmental issues

Abstract

Along with the positive factors of the conservation tillage system, it impose the use of pesticides in greater quantities, which affects negatively soil microbiological activity and affects the agricultural environment. Within SAUM (The department of Soil Science and Agroecology) were highlighted several positive aspects of conservation tillage implementation, less were investigated environmental aspects and imposed problems. In the sustainable agriculture, the efficiency of conservation tillage system should be based on energy inputs evaluation, along with the characteristics of soil vitality. Aims: Comparative agroecologycal research of conventional and conservation soil tillage systems by evaluating energy efficiency, soil respiration and cellulolytic activity.
