Goal. To determine the most adapted wood breeds for plantation afforestation of different function in the conditions of drained peatlands of the Forest-Steppe. To study the peculiarities of growth and development of newly created forest crops in specific conditions of organogenic soils. To determine the influence of afforestation on the change of water-physical properties of drained organogenic soils. Methods. General scientific (hypotheses, inductions and deductions, analogies, generalizations) and special (field, laboratory, mathematical, statistical, computational) — for research and their generalization. Results. The best indicators of productivity in these conditions were shown by tree and bush willows, black poplar, sticky alder, and hybrids of Euro-American poplars. The optimal length of unrooted cuttings for the creation of energy plantations was 25 cm. For afforestation of black alder on drained organogenic soils, it is advisable to create forest crops with seedlings 1.0–1.2 m high according to the scheme 3.0×1.0 m, which ensures survival at the level of 98%. Over the last 52 years, the density of peat in the upper layer (0–30 cm) in the forest stand has not changed (the difference is 3%), while in the lower layers it has increased by 18–20%, but the soil density remains low (average 0.250 g/cm3) and high total moisture content (345%). The decrease in soil mineralization in forest stands compared to hayfields indicates a slowdown in the decomposition of peat organic matter under the forest, which is important for the preservation of peatlands. After the cycle of plantation afforestation, re-agricultural use of lands with improved water-physical properties of the soil is possible. Conclusions. The creation of forest plantations on drained organogenic soils is quite possible and expedient. With the use of different species composition and changes in planting density, you can create plantations of tree crops for different purposes. The highest indicators of productivity in these conditions had tree and bush willows, black poplar, alder sticky and hybrids of Euro-American poplars.
