title: [Changed soil properties after pollution by oilfield brine at the Tuimazy oilfield (Republic of Bashkortostan)].
abstract: Changes in the main soil properties under the influence of oilfield brines were studied at the Tuimazy Oilfield. High salinization was observed in the cinnamonic forest soil one year after pollution. Progressing alkalinization deteriorated the main soil properties. The chemical composition of the aqueous extract and the ionic composition of the soil absorption complex changed, the base exchange capacity decreased, the humus state deteriorated, and enzyme activity was suppressed. In the meadow calcareous chernozem polluted 12 years ago, desalinization processes increased alkalinization and thus further degraded the soil.
