The content of labile organic matter in April amounted to 3.64 ± 1.55 mg/g of soil and decreased to 2.29 ± 0.30 mg/g in July, showing minimal variability due to the stabilizing effect of forest litter. The highest content of water-soluble organic matter was also recorded under forest conditions (0.36 ± 0.04 mg/g in May), decreasing to 0.26 ± 0.01 mg/g by July, while remaining higher than in agriculturally used variants. In 2024, soil CO₂ emission dynamics varied significantly depending on land-use type. In April, the highest emission was observed under perennial grasses (3.79 µmol s⁻¹ m⁻²), whereas under miscanthus and forest the values were 2.26 and 2.21 µmol s⁻¹ m⁻², respectively; the lowest emission occurred in crop rotation (1.07 µmol s⁻¹ m⁻²). In May, emissions decreased across all variants, with a peak in June, reaching 7.01 µmol s⁻¹ m⁻² in crop rotation, 5.96 µmol s⁻¹ m⁻² under perennial grasses, 4.62 µmol s⁻¹ m⁻² under forest, and 3.79 µmol s⁻¹ m⁻² under miscanthus. In July, emissions declined again, remaining highest under perennial grasses. Under field conditions, miscanthus produced a dry biomass yield of 11.2 t/ha, while perennial grasses reached 14.5 t/ha, with the largest contribution from the first cut (8.27 t/ha). Carbon removal with perennial grass yield amounted to 6.73 t/ha, exceeding that of miscanthus (5.42 t/ha) and maize (5.33 t/ha).
