The influence of treatment methods on agrophysical soil properties and old Eastern galega stand root development

Abstract

All mechanical effects are primarily aimed at improving soil conditions and the root system. Different treatment methods with different types of working organs affect the fractional composition of particles, agrophysical soil properties, and the ability to restore the root system of old-age, degraded stands of perennial grasses with a root-shoot root system. The article presents data on the results of three field experiments (2017–2019). An analysis of the fractional composition of soil with various cultivation methods was carried out, and the relationship between the number of first-order roots of the eastern goat grass stand and agrophysical soil properties was identified. The maximum soil fraction was 7 and 10 mm when treating with a BDT aggregate in one track, the minimum percentage was observed when treating with a Leader aggregate in two tracks to a depth of 10–12 and 16–18 cm. The greatest “clumpiness” of fractions was revealed with a smaller number of treatments. The optimal soil conditions for the growth and development of the root system of old-age goat grass stands in the 0–20 cm layer were established during flat cutting. By the end of the growing season, the number of first-order roots increased from 15,000 to 22,000 thousand units/ha.
