Abstract
The choice of rational parameters and their optimization with respect to aggregates of strip processing has not been paid enough attention. This is especially true of the quantitative values of the quality parameters of soil cultivation, therefore, it is necessary to consider several quality indicators simultaneously and use a generalized indicator that takes into account the correspondence of the condition of the treated strip to the agrotechnical requirements of the presowing treatment. The most characteristic is the dependence of the generalized index of the quality of strip processing on the parameters of working organs, soil properties and high-speed operation modes of the unit. The article substantiates the use of the generalized quality indicator of strip processing on the basis of individual indicators, taking into account their importance and developed methods for their determination, generalized agronomic requirements for technology of strip processing of soil. The quality of strip processing is first determined by visual inspection of the treated strip, paying attention to the uniformity of placement of soil aggregates, the general condition of stubble and plant residues. The depth of processing is determined using a Revyakin hardness tester or a measuring rod. The transverse unevenness of the surface of the strip is determined by the method of lengthening the cord when copying the relief of the soil or by profiling the height of the ridges and the depth of the furrows. Tubbiness is determined by superimposing a rectangular accounting frame with an area of 0,24 m2 (40 × 60 cm), with cells measuring 50 × 25 mm, to the surface of the treated strip. The working organs of the machines for strip processing should evenly process the soil to the depth of the seedbed, and not clog the soil and plant residues. Compliance with agrotechnical requirements for strip processing will ensure the possibility of performing a deep, uniform loosening with the application of fertilizers, the formation of a quality seedbed and further planting of crops.

Dependence of productive and technological indicators on breeding value of dairy breeds heifers
The heifers of dairy breeds with high breeding value (SI > 1500) are charac-terized by maximum productive traits that exceed the average for the herd. That makes it possible to predict the results of breeding work on the...
Running systems of modern agricultural machinery
Economic efficiency in modern agriculture predetermines the use of large, heavy equipment, which, in turn, can cause compaction not only of surface soil, but also of deeper subsurface soils. The problem is gradually beco...
