FIELD: agriculture.
SUBSTANCE: hyperaccumulant plants tansy-leaved phacelia (Pacelia tanacetifolia Benth.) are grown on contaminated soils with their subsequent removal. Seeds of tansy phacelia are sown in early spring in contaminated soil at the rate of 10-12 kg/ha with a row spacing of 15-20 cm and a seeding depth of 1.5-3 cm, before the end of the blossoming phase and the beginning of seed ripening, after which plants are completely removed. The removed biomass is utilized by composting and subsequent use as a source of zinc in combination with mineral or organic fertilizers.
EFFECT: improvement of the ecological state of agricultural biogeocenoses due to the removal of excess zinc by plants from the soil and restoration, improving the quality of agricultural land.
