The paper presents the quantity and quality of salts in the solonchaks of Central Fergana. Soda was found in the profile of solonchaks in the amount of 0.08-0.19%. Solonchak vegetation is characterized by high ash content, while it is found that in salt marshes of the desert zone, arsenic accumulates in the amount of 7-8 CC, the biological absorption coefficient is 1.17-11.9.
