Analysis of Soil Tillage by Ploughs and Optimisation of Their Aggregation

Abstract

The mechanical and technological aspects of the impact of ploughing upon the soil fertility have been analysed, as well as the frequency of its crumbling and restoration of the strength of the structure in the arable horizon under the current conditions of agricultural farming. So, a decision on the need for ploughing with a mouldboard plough is not taken every year, but when the soil structure coefficient of the upper layer (8-10 cm) is less than 0.67. A rational of use of mouldboard ploughs with coulters (or application of double-depth ploughs) is substantiated. Scientifically-grounded recommendations for the aggregation of the ploughing machine-andtractor aggregates have been presented. Reduction in the energy costs of ploughing can be ensured by introducing a correct system of aggregating the ploughing tools with energy resources.
