During the first two years, soil pH, humus content, and NPK levels remained relatively stable, whereas bulk density, structural–aggregate status, CO₂ emissions, and indicators of labile and water-soluble organic matter proved to be the most sensitive indicators of change. In the first year, miscanthus cultivation impaired soil structure and increased bulk density, while perennial grasses and a vetch–oat mixture improved soil physical properties already during the initial year of use. In terms of productivity and ecosystem functions, perennial grasses demonstrated the highest potential: the average annual dry matter yield amounted to 11.67 t/ha, energy productivity reached 204 GJ/ha, organic carbon removal was 5.41 t C ha⁻¹ yr⁻¹, and economic return approached 89% over three years. Miscanthus ensured stable biomass production (11 t/ha from the second year onward) and a substantial carbon flux; however, due to high initial establishment costs, it remained unprofitable within the three-year cycle. The four-field crop rotation was stable but less effective in terms of carbon return and biomass formation. Overall, the use of perennial grasses represents the most environmentally and economically viable strategy for the restoration of degraded post-forest lands, whereas miscanthus requires a longer payback period and provides higher carbon-use efficiency in the long-term perspective.
