Optimization of nitrogen nutrition of grasses on oil-polluted oligotrophic peat soil

Abstract

The paper demonstrates the importance of creating optimal conditions for mineral nutrition of cereal grasses and microorganisms in oligotrophic oil polluted peat soil under remediation. To establish the effectiveness of using various forms of nitrogen fertilizers in oil pollution, changes in the agrochemical properties and enzymatic activity of the soil, the productivity of cereal grasses and the amount of DNA prokaryotes were investigated. A significant increase in the productivity of plants and the number of bacteria and archaea in oligotrophic peat soil is shown when optimizing nitrogen nutrition, especially pronounced when introducing the ammonium-nitrate form of fertilizer. There is a close relationship between catalase activity in soil and residual oil content in soil.
