PASHCHENKO V. Mechanical and technological means of ecological and economical improvement in soil cultivation processes.

Research object: technological processes of soil cultivation. Aim of research: to improve an ecological and economical effectiveness in crop cultivation by energy use lowering to cultivate the soil and the duction of negative influence on it by means. Research methods and apparatus: the researches were carried out by means of higher mathematics methods, those ones of classical mechanics and multifactor experiment planning methods. Theoretical and practical results: the theory of mathematical modelling in interaction process of working organs with the soil. The means of ecological and economical soil cultivation to optimize agro-physical properties of arable soil layer by unification process of change and separation in lumps were made. The bases of theory to ground the parameters of supposed working organs were formed. Novelty of the newly introduced: the theory of mathematical modeling using a direct variation calculation. The theory of maximum condition in loose environment in the direction to studythe processes of working organ and soil interaction was developed further. Introduction level: the experimental models of machinery to cultivate a soil arable layer were made. The technical tasks to make the sowing-machines and the cultivator were worked out. "Rut" technology to cultivate sugar beets was introduced on the area of more than 2000 ha. Sphere of use: agriculture.
