The chemical composition of replantozem in the recovery process in the recultivated area

The chemical composition of the replantozem in the recovery process on the reclaimed oil-polluted area was studied: pH of the soil solution, the content of oil products, chloride of ions, phosphorus, manganese, calcium, calcium, iron, aluminium, ammonium and magnesium, as well as organic matter. The activity of the proteolytic enzyme protease and cellulase in soil substrates was determined. The aim of the work was to monitor changes in the chemical composition of replantozem in the process of their self-healing. Research methods: pH of water - by inoLab 740 conductometer, organic carbon amount - by the method of determining the organic matter by the photometric method of Tyurin according to TsINAO for mineral soils, total Fe2O3, total Al2O3, MnO2, mobile forms of P2O3 phosphorus. the results showed a decrease in the concentration of petroleum products, the pH shifts in a neutral direction, a decrease in chlorides...
