Energy efficiency of the use of chicken droppings under white cabbage and potatoes on meadow-black soil

Conservation, reproduction and rational use of agricultural soil sprees are the main condition for the stable development of the agro-industrial complex. The use of avian litter fertilization in the fertilizer can have a significant positive impact on soil fertility and crop productivity. The aim of the research is to study the impact of avian litter on the productivity of cabbage and potatoes with a bioenergy justification for its use in Western Siberia. The research was conducted on the experimental field of the Omsk GAU in 2015-2017. Objects studied: potato-fel (sort of hostess), cabbage white cabbage (variety Gift), meadow-black-black-lo-powerful small humus heavy-fat soil and litter chicken droppings. Studies have established a high efficiency of the use of chicken droppings when making it under cabbage white cabbage and potatoes. The most effective was noted in the 12 t/ha of bird droppings. The introduction of elevated doses (16 and 20 tons per hectare) did not lead to a further reliable increase in the yield of cabbage and potatoes. The calculation of the energy efficiency of using organic fertilizers on the basis of litter edging chicken droppings showed that the use of littered potatoes varied from 3.50 to 9.03 when cabbage was cultivated white-cabbage and potatoes bioCPD. The highest energy efficiency of the use of bird droppings for cabbage and potatoes was obtained at 4 t/ha (efficiency 7.47 and 9.03 respectively), the lowest - with the use of 20 tons per hectare (3.50 and 4.51 units, respectively).
