Assessment of the impact of agricultural technologies on the fertility, health and stability of chernozem

Abstract

This study aimed to comprehensively evaluate the effects of agricultural technologies on the quality, health, and stability of slightly eroded chernozem in grain crop rotation using the author's methodology. The research was conducted on the experimental field of the Kursk FANC from 2018 to 2021. Three agricultural technologies were tested: a traditional method with crushed by-products (PP), agrobiotechnology-1 (PP and microbiological preparations), and agrobiotechnology-2 (agrobiotechnology-1 + 10 kg a.i. N per 1 t of PP). The results showed that all technologies had a satisfactory impact on soil fertility, health, and stability, with most indicators remaining unchanged. Agrobiotechnology-1 had a good impact on soil fertility and stability and an excellent impact on soil health. Agrobiotechnology-2 had an excellent impact on soil, with significant and highly significant increases in most indicators. The comprehensive assessment indicated that agrobiotechnology-2 had the highest overall impact, with a Kcomp value of 21.4%.
