Production of bentonite and humus natural organic substances from fluoride compounds

“…If the amount of substances in the soil-plant system Down system is acceptable, they can be used to grow food crops. At the same time, it is necessary to: optimize the nutritional conditions of crops grown using organic and mineral fertilizers, which often significantly reduce the penetration of toxic elements into cultivated plants; selection of field and vegetable crops that, due to their genetic nature, absorb less toxic substances from the soil and do not respond to the presence in the soil to certain value chemical reclamation of soil (plastering of acidic saline soils), which has a certain positive effect even when the soil is contaminated with fluoride; Systematic monitoring of the amount of pollutants in agro-ecosystems [4][5][6][7].…”
