Abstract
Purpose. Investigation of the causes of compaction of arable and subsoil soil layers of deep podzolic chernozems. Methods. Experimental studies of the density of arable and subsoil soil layers of deep podzolic chernozems with subsequent processing of the results on a PC. Results. The results of experimental researches of formation of the overcompacted layers of chernozems of deep podzolic depending on ways and means of influence on them are stated. Conclusions. As a result of research it is established that on deep chernozem chernozems the maximum depth of overcompacted layers formed by self-compaction for virgin soil does not exceed 30 cm, and man-made impact on these soils leads to overcompaction of layers up to 40 cm deep. Possible areas of further research on this issue are the study of technical and technological aspects of ensuring acceptable for optimal plant development density. Keywords: overcompaction, arable and subsoil layers of soil, division of chernozems deep podzolic, running systems, soil density.
