Information × Registration Number 0211U002975, 0106U007910 , R & D reports Title To develop scientific bases of the system of agriculture, adapted to the natural conditions of the unsteady humidity of Forest-Steppe zone. popup.stage_title Head Schapoval I.S., Registration Date 15-03-2011 Organization The Cherkassy Institute of agroindustrial production of the UAAS popup.description2 Object of researches: physical degradation of black soil. Aim of researches: development of approaches for the physical degradation of black soil stopped. Methods of researches: field method, laboratory method, statistical method. At ploughless and superficial tills of black earth the optimal closeness of structure keeps indoors outside optimal values, that is provided by the improvement of the structure-agregation state and results in optimization of construction of porous environment due to an increase agronomical of valuable factions of structural parts and waterproof aggregates. Тhe ploughless till is inhibited processes of nitrification in comparing to ploughing on 4-15%, in the same time nitrificationing ability of overhead part of humus horizon rises in 1,3-1,8 times. At implementation of superficial till ability of black earth to resist to the change of active reaction of the ground solution (bufer capacity) a 0-40 sm increases due to enriching of layer of soil carbonates (content folds 0,55%, stocked - 28 t/ha). There is itself lime of black earth. Application of ploughless till of soil promotes weedsing of sowing in a crop rotation in 6-13 times, comparatively with comparatively with ploughing.
