In the article, main principles and methodical bases of the complex analysis of actions for research of influence of influences on soil subject to erosion are stated at cultivation of agricultural crops for the purpose of preservation and increase of its fertility

In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established

The results of pilot research in the investigation of the effect of gouge which was formed with the scoop of the effector of the horticultural chisel plough during the row-spacing cultivation about the outline of a root age bedding on macro and microstructure of soil aggregates, the alteration of quantum indices subject to intensity and duration of culti-vation are given in this article

In the article, we have considered the questions of mathematical modeling of a combined soil-cultivating unit. Theoretical dependences and rational values of parameters and unit operating modes are received

In the article, the questions of substantiation of a way of the maintenance of soil in gardens on hillsides, the constructive scheme of the rotational garden mower providing cutting of vegetation at different levels are considered

This work is devoted to the research of the thin-walled cylinders’ surface roughness dependence upon the modes of processing by the roller head. The research was made on the machine 1K62, preliminary treatment – boring and unfolding

In the given article process of mathematical modeling of a mechanical trajectory of a drip of a fluid from a surface of upright gyrated disk sprayer is featured, for chemical protection of young fruit plants

In article questions of optimization of quantitative and branded structure of park of tractors on a minimum of capital investments for the basic technological operations are considered
