The monograph outlines the basic concepts in the field of improving the efficiency of pre-sowing tillage and the exclusion of shortcomings in the preparation of soil for sowing, the necessary performance of technological operations without a gap in the agro-term. The fulfillment of soil tillage in short time only on special combined aggregates for pre-sowing tillage is considered. Development of measures on improvement of agrotechnics of cotton cultivation on which one of the first places consists of pre-sowing soil treatment, qualitative realization of which serves as a foundation for the future harvest is considered. The monograph is intended for engineering and technical and scientific workers in the field of agriculture, as well as for researchers, applicants, masters and students of technical and agricultural universities.
