Abstract
The aim of the research is to assess the effect of deep loosening with an improved reclamation ripper on changes in the agrophysical properties of heavy soils. The paper presents the results of studies of the effect of the improved design of the working body of the reclamation ripper on the main agrophysical indicators of the soil, including soil structure, density, humidity, porosity, as well as other technological and energy characteristics of the loosening process. The results of field studies of the loosening process and its efficiency on uncultivated soils of natural composition are considered. It has been established that for the effective regulation of physical and mechanical indicators of soil properties depending on the needs of plants and the development of technology for their cultivation, knowledge of the parameters and optimal values of these agrophysical properties is required. It has been determined that as a result of deep volumetric loosening of over-compacted gley soils with a working body of the developed design, for which a number of patents for inventions have been obtained, a homogeneous oil structure is formed, the soil density decreases to 1.2… 1.3 g/cm3, the porosity increases to 50% along the depth of the treated profile, which contributes to an increase in water capacity and productive moisture reserves; the results of the experiments made it possible to assess the degree of improvement in the agrophysical properties of soils as a result of deep loosening.
