Online published on 9 March, 2021. Abstract Soils of the Rostov-on-Don Zoo were investigated in 2017-2020. The objects of research were aviaries with birds (Grus grus , Pavo cristatus , Branta canadensi and others ), Chapman's zebras ( Equus burchelli chapmani ), red deer ( Cervus elaphus ), which were subjected to seasonal migrations-in the spring to the emu aviary ( Dromaius Vieillot ), in the summer in the guanaco aviary ( Ama glama ), two-humped camel (Camelus bactrianus ), blue rams ( Seudois nayaur ), the arnee Buffalo, the white rhinoceros ( Ceratotherium simum ), the Rothschild giraffej (Giraffa camelopardalis rothschildi ), domestic donkeys ( Equus asinus dom ). The control was a section of the park zone of the zoo with minimal anthropogenic impact. The soil and vegetation of the control site was typical of most of the zoo. The soil of the study area is ordinary black soil (haplic chernozem Loamic), widely distributed in the steppe zone of Russia. Soil monitoring showed a significant violation of the ecological condition of soils and soil cover. The main problem of the soil in the enclosures of the zoo is to increase the bulk density, the destruction of the soil structure, and soil pollution by waste products of animal vital activity. Soil respiration in the enclosures of the zoo is increased due to the additional intake of organic substances into the soil with animal metabolic waste. The use of various ameliorants (river sand, glauconite, acrylic hydrogel, sawdust, microbiological preparation) can help improve the ecological condition of soils and increase biological activity. This will help accelerate the processes of biological decomposition of pollutants accumulated in soils. Sawdust proved to be better than other ameliorants for optimizing the ecological state of the zoo's soil. Top Keywords Soil quality, Biological activity, Animals, Bioindication, Ecological state.
