【 摘 要 】

The article reflects negative physical and chemical properties of the bore muds in respect to Tyumen region (high dispersion, swelling ability, ash structure, crust formation, low filterability, a high degree of salinization, alkalinity and toxicity). Indicated properties are mainly stipulated by the increased content of exchangeable sodium in the absorbing complex and by the presence of soda in aqueous solution. The source of absorbed sodium and soda in water extract is the use of caustic soda in the drilling mixture. It was found out that these negative properties are illuminated using coagulant in a form of phosphogypsum - waste of chemical industry. Necessity in the nitrogen for the bean cultures-phytomeliorants is provided at the expense of legume bacteria in a form of the rizotorphin formulation. It is worth noting that growing of legume bacteria in extremely salted breeding ground on the leguminous agar has allowed choosing the most salt resistant species among the numerous strains of Melilotus officinalis and medicago. The presence of phosphorus in phosphogypsum positively influences the productivity of leguminous crops in the beginning of recultivation.
