 The highlighted research results describe the processes of nutrient accumulation and energy accumulation in the systems of non-traditional fertilizer - technosoils - energy grass and wood trees of short rotation presented. Technosoils have their own specific features depending on the type of minerals and methods of their extraction. Most of the mining substrates of the Nikopol manganese ore deposit are suitable for the creation of industrial plantations of energy crops. The most favorable for growing miscanthus are loess-like loam, red-brown clay and their mixture. Dark gray shale clay is not suitable for growing miscanthus as an energy crop due to low productivity. The best substrates for switchgrass are red-brown clay, loess-like and red-brown loam, as well as gray-green clay. Variants with chernozem and dark gray shale clay are the worst in terms of yield. However, the productivity of switchgrass on dark gray shale clay is higher than that of miscanthus, so the use of this substrate to obtain raw materials of switchgrass is quite appropriate. The use of soil amendments is appropriate to increase energy yield with biomass of fast-growing perennial grasses on low-yielding reclaimed land. The use of biochar as soil amendments in technosoils has a double effect on energy crops: increasing the growth of biomass and reducing the ability to accumulate heavy metals. In general, a larger increase in yield observed for leaf biomass. Biochar has an indirect effect on the thermal characteristics of the biomass of energy crops. Prospects for the creation of plantations of fast-growing woody crops with a short cycle of cultivation (Populus nigra, Ailanthus altissima, Elaeagnus commutata, Robinia, Paulownia clone 112, etc.) on reclaimed lands have been proven under the conditions of choice of species and cultivars. The specific properties of techno-soils have a certain influence on the energy properties of woody plants.
