- Intervention effect Humus content in variants with permanent wheat decreased to 3.26-3.38%, relative to the virgin plot standard.
- Intervention effect The greatest decrease in humus content (2.48%) occurred in the two-field grain and fallow crop rotation.
- Mechanism The authors attribute the humus decrease to insufficient intake of plant residues and mineral fertilizers.
- Observation The content of nitrate nitrogen and mobile phosphorus in virgin soil is low.
- Observation Ammonifiers and immobilizers dominate on cultivated soils.
- Mechanism The high carbon dioxide emission on virgin land (3.0 C 2 kg/ha/hour) is attributed to a large amount of plant biomass.
- Recommendation The authors recommend cultivation of permanent wheat with fertilizers and herbicides as the most optimal variant, raising yield up to 15.8 c/ha while preserving soil fertility (3.26% humus).
