Description
In the article we have studied the technology of obtaining a biomass of oil oxidizing microorganisms in a nutrient medium containing vegetable oil as the sole source of carbon and energy. In vitro and in soil experiment we have confirmed the effectiveness of the resulting biomass at work on bioremediation of oil contaminated sites. It is shown that the use of vegetable oil during culturing allows obtaining the same amount of biomass and carbohydrate raw materials, but the efficiency of its use is 20% higher, in average

EFFICIENCY OF IRRIGATION REGIMES FOR GRAIN SORGHUM ON CHERNOZEMS
06.00.00 Agricultural sciences
DescriptionThe article results the study of irrigation regime im-pact on water consumption and yield of grain sor-ghum. It is established that optimal conditions for growth and development are created by maintaining soil moisture content in a soil layer of 0.6 m higher than 80 % of field capacity (FC), where the grain yield reaches 14 t/ha and the best indices of profit and cost-effectiveness are obtained
