Abstract

The paper presents results of a study on degradation of arable soils in the Trans-Urals forest-steppe and the efficacy of a synergistic technology combining subsoiling without inversion with biochar application. Agrochernozems and agro-gray soils at the experimental farm of Kurgan State University showed compaction up to 1.59 g/cm³ and poor aggregate composition. Penetrometry data demonstrated that the combination of subsoiling and biochar (5 t/ha) significantly (p < 0.05) reduces penetration resistance in the plowpan zone (10–30 cm). The core principle is synergy: subsoiling eliminates mechanical compaction while biochar creates artificial aggregation that stabilizes structure until native soil aggregates recover. A climate project with dual certification (PNST 901–2023 / Verra VM0044) is implemented in parallel. The approach enables integration of restoration technologies into ongoing agricultural production without halting operations.
