Abstract
The purpose. To determine theoretically possible volumes of vegetable biomass which can be used for power conversion. To justify inexpediency of use of a part of collateral products of plant growing for power purposes because of lowering fertility of lands of agricultural assignment of agrarian and industrial complex of Cherkassy oblast. Methods. Field and laboratory experiments, agrochemical diagnostics study, comparative- and-analytical method. Results. At exception of collateral products for power purposes (straw of cereal and leguminous crops, soya bean and rape), that makes about 20% of the common yield of collateral products, balance of organic substance of humus attains deficiency of the level – 0,19 t/hectare, that is in 190 times deficient. Thus deficiency of nutrients increases for 125 %. Conclusions. Increase of deficiency of humus and nutrients at exception of collateral products for power needs causes inexpediency of utilization of collateral products for that purpose because of lowering fertility of lands of agricultural assignment.

Key words: balance of humus, collateral products, biofuel, humus, nutrient elements.
