Agrobiological principles of environmental protection and efficient use of drained organic soils under climate change

Goal. To determine the optimal parameters of combination reclamation, agricultural, and nature protection solutions to ensure sustainable development agricultural production in humid zone on drained soils. develop measures aimed at reduction degradation organic soils improvement their fertility based sound environmental system agriculture energy-saving technologies for growing crops conditions global climate change. Methods. Field with a complex biometric, agrochemical, laboratory research, mathematical statistical. Results. On old arable well-mineralized carbonate soils, creation nature-preserving agro-landscapes yield 9–10 t/ha feed units high-quality fodder from perennial grass mixtures; 8.4–8.7 corn grain more than 4 winter rye triticale will introduction 8-field crop rotations 5–6 fields mixtures 2–3 annual application mineral fertilizers rate P40–45 K120–130 kg acting substance under addition N45 grasses, which helps reduce mineralization matter accumulation mobile nitrogen compounds mixtures. In addition, nutrients are intensively leached into groundwater by compared is an important conservation measure when creating rotations. Conclusions. Such provide nitrate 0–30 cm soil layer times, evidenced significant decrease peat its leaching river waters.
