Abstract

The study of suitability for the use in agriculture of sludge deposits and hydrochemical indices of water bodies of fish-growing enterprise of LLC “Albashi” were carried out. It is an enterprise engaged in breeding and growing pond fish and sturgeon in pools and gardens, crayfish, growing aquapon greens. Fresh water bodies of reservoir type LLC “Albashi” contain a large number of bottom deposits. The layer of sludge deposits on the bottom in places reaches the power of 2-5 meters, and the underground power is difficult. Bottom sediments were taken from a depth of 1.0-1.2 m from the surface. The hydrochemical regime of the studied water bodies fully corresponds to the cultivation of aquaculture objects and hydroponic plants. Sufficient suspended matter in water (8.2 mg/dm³). The complete absence of dichlorodiphenyl trichloroethane, its metabolites and pesticides characterizes the products produced as environmentally safe. Consequently, bottom sediment site under study can be considered suitable for agricultural production.
