The paper considers some issues relating to the evaluation of oxidation-reduction (redox)properties of soils using a system of titration methods with oxidizers and reducing agents, and controlled-potential coulometry on electrodes from a soil-coal paste. The redox status of soils can be additionally evaluated using the gas-discharge imaging method through determining the anti-radical activity of soil solutions and the content of antioxidants, carbon dioxide and oxygen, as well as positively and
