ECONOMIC AND ENERGY EFFICIENCY OF FERTILIZING SYSTEMS OF AGRICULTURAL CROPS UNDER ACTION OF MICROBIAL PREPARATIONS IN SHORT ROTATION OF CROPS
Journal Title: Сільськогосподарська мікробіологія - Year 2018, Vol 28, Issue
Abstract
Objective. Carry out economic and energy evaluation of fertilizing systems of agricultural crops, including for the use of microbial preparations. Methods. Field, laboratory, statistical-economic, calculation-comparative. Results. On the basis of studies in a long-term field experiment on sod-podzolic soils, economic and energy estimation of crop cultivation in the crop rotation line: lupine - winter rye – potato - oats-was carried out depending on fertilizing systems and pre-seed bacterization of seeds. The prospect of improved organomineral fertilizing system “animal manure + NPK + green manure” has been shown. This fertilizing system provides growth of the conditionally pure profit of crop rotation by UAH 6,922/ha. Using fertilizing system “animal manure + NPK + green manure” for cultures of crop rotation provides an opportunity to increase the conditionally pure profit 2.2 times in comparison with the mineral fertilizing system. With the addition of green manuring to mineral fertilizing system, the conditionally net profit increased from UAH 3,066 to UAH 4,598/ha, or by 50 %. Due to the use of microbial preparations for inoculation of seeds, the profit increases by UAH 1,641/ha, and the return on costs is provided for UAH 1 at the level of UAH 5.09 to 8.10. For energy efficiency, the alternative organic-mineral fertilizing system (animal manure + NPK + green manure) exceeded the traditional one (animal manure + NPK) by 43 % without the use of microbial preparations and by 61 % using biopreparations, and mineral – 2.6 times. The obtained results demonstrate significant prospects for the biological factors of fertilization of crops for their cultivation in short crop rotation. Conclusion. The application of organo-mineral fertilizing system (animal manure + NPK + green manure) in combination with microbial preparations in the cultivation of crops in short crop rotation provides high economic and energy efficiency.
