Suleimanov R.R., Nazyrova F.I. CHANGES OF SOIL BUFFERING AT POLLUTION WITH OIL-FIELD WATERS AND CRUDE OIL Changes of buffering characteristics of grey forest soils at pollution with highly mineralized oil-field sewages (OFS) and crude oil are studied in this article. It is shown that soil pollution with OFS leads to abrupt increase of buffering indexes at acid interval and to decrease – at alkaline. Restoration measures including entering of phosphogypsum and dung promote increasing of its general buffering. The degree of soil-absorbent complex degradation is increased with the antiquity growth and the level of original pollution at destruction of crude oil during the process of biological restoration of light-grey forest soils as a result of second salinization and alkalinization. Shift of acid-alkaline conditions leads to abrupt buffering decrease at acid interval.
