Abstract

Goal. Show changes in the content of humus, agrophysical properties of the typical black soil and isohumus of the temperate zone of the forest-steppe zone in different technologies of their use in the subzone of broadleaf forest-steppe (Ukraine) and Prairie (China). Methods. Field: core, breeding sample; laboratory: gravimetric, sieve, oxidimetric; statistical - dispersion analysis. Results Changes in parameters of humus, composition density, structural and aggregate state of chernozems in various soil cultivation technologies have been established. Conclusions The investigated chernozems are characterized by optimal and close to optimal agrophysical properties for growing corn on grain. The use of no-till on isogumbulose and shallow planar cultivations on typical chernozem contributed to the formation of a less densely, more humus layer of 0-20 cm, an increase in the content of agronomically valuable airborne and water-resistant aggregates. For plowing, the best humusoon accumulation in the layer of 10 - 20 cm typical black soil occurred, a less densified layer of 0 - 10 cm isohumulous was formed, more micro aggregates <0.25 mm were formed for dry and wet sifting.

Key words: chernozem, soil cultivation, humus, aggregate density, aggregates.
