The article presents analytical materials of studying the chemical composition and properties of bird droppings in the Pokrovskaya PTF LLC of the Engels District of the Saratov Region. Its various types: dry, litter, dense consistency, semi-liquid, liquid, drains are analyzed. The loss of chemical elements at perfect and impaired storage technology and ways to prevent them are identified. The most promising of them is thermal drying. The specificity of the impact of high doses of bird droppings on the fertility of the fields adjacent to the poultry complex was revealed. Its effect on the reaction of the soil solution, the humus content, mobile forms of nitrogen, phosphorus, potassium, sulfur and trace elements is shown.
