The article provides a study of the influence of anthropogenic, techno genic factors on the accumulation of heavy metals in the soils of the Fergana region, especially in the subsoil. Since the greatest accumulation of harmful substances in the air accumulates in the soil, and plants absorb them, at least in part, that is, with air-precipitation-water basins, rivers-irrigation watersoil circulation occurs. Many years of field experiments have shown that when phosphorus fertilizers (superphosphate) are taken 3-4 times more, an increase in nitrogen is observed due to a sharp decrease in fluoride content. Especially grown on cotton leaves and stems.
