Recently, due to the deterioration of the ecological situation and in order to rehabilitate soils, increase their fertility and resistance to water and wind erosion, world science and practice are turning to biological agriculture, based on the elimination or significant reduction of the use of mineral fertilizers and pesticides and the widespread use of biohumus - a product of the life of rainworms.
The purpose of the research is to assess the energy efficiency of the vermiculturing process.
Efficiency of the processes of energy conversion during bioconversion of organic waste in biohumus and protein feed is considered on the example of a protected cultivating structure of the ground type, which allows year-round to receive valuable products for agriculture.
he components of the equation of the energy balance of vermiculture are analyzed and the degree of their influence on the bioenergy efficiency coefficient is determined.
To ensure optimal microclimate in a vermicular plant, quantitative assessment of the parameters of the temperature-humidity regime is required. The solution of this problem is possible on the basis of the equation of thermal balance, compiled for the most severe temperature conditions in a vermicultivating structure. Such conditions take place during the winter period of its exploitation.
Electricity costs can be greatly reduced by using different means of insulation of vermiculture plants: straw mats, paper and foam blankets.
No less significant effect on the energy efficiency of the vermiculturable structure is the ratio of power substrate and airheating elements. As is known, the temperature of the substrate is determined by the technology of vermicultivation and should be maintained at a constant level. The air temperature in the vermicular cultivating plant depends on the conditions of the environment and the ratio of the capacities of substrate and air heating elements
As a result of the conducted research it was established that the significant influence on the energy efficiency of the vermiculturable structure has the correlation of the capacities of the substrate and air heating elements. Daily electricity consumption is stabilized and becomes the minimum value with the ratio k> 2-3.
Key words: vermicultivation, energy consumption, livestock wastes
