The soils of the Chechen Republic are distinguished by a significant difference in morphological and agrochemical properties, which are clearly visible both in the vertical and horizontal directions. The purpose of the study is to study the possibility of using grain crops for the environmental assessment of oil-contaminated soils. The study was conducted in the period 2018-2021. on the territory of the Chechen Republic. An average soil sample (about 150 cm3), which was taken from a depth of 0-20 cm, the experiment was repeated 3 times, was placed in a container, where seeds of winter wheat and oats were subsequently sown. In each variant, the growth and development of test plants were studied. The seedlings were thoroughly washed from the remnants of the earth, dried with filter paper, then weighed, the length of their roots and the height of the sprout were determined. It is most expedient to use winter wheat (Tanya variety) as test plants. It is possible to use the biological resource of plants of the Cereal family in order to assess the level of oil pollution. During the bioindication study, it was found that the germination of seeds of a test plant (winter wheat, variety "Tanya") varies depending on the type of additional treatment of oil-contaminated soil: 65-92% and 69-94%, respectively. A similar pattern was established for all other indication criteria.
