Taras U. Restoration of plant groups on the devastated lands of Yavoriv sulphur pit.

The object of study - edaphic conditions, plant communities and micromycetes on the devastated lands of the Yavoriv sulphur quarry. The aim is to establish the patterns of restoration of soil and vegetation cover on the devastated lands of the Yavoriv sulphur quarry, to identify the role of micromycetes in improving edaphic conditions and enhancing the efficiency of cultivation of forest crops. Research methods: the following types of analysis were applied - system analysis, silvicultural, pedologic, geobotanical, ecological, mycological, agricultural, radiological, phitomeliorative , mathematical statistics. Scientific novelty - it was found that the process of self-restoration of soil conditions, micromycetes and vegetation cover on the devastated lands of the Yavoriv sulphur quarry 20 years after its closure is in the initial phases and needs phytomelioration, remediation and other active recovery methods; identified were the features of coenoflora of the devastated land of the sulphur quarry, which is characterized by low species diversity dominated by herbaceous geliophytes of mesophytic and mesotrophic habitats, tap-rooted and rhizomatous plants. Practical importance - based on the system-morphological analysis of the soil, the arbuscular-mycorrhizal fungi agent was developed to improve the survival and adaptation of forest crops to the sulphur-contaminated soil. Assessed was the environmental efficiency of the arbuscular-mycorrhizal fungi agent in biological recultivation of lands devastated by sulphur-mining operations. Areas of use: forestry.
