Background

The process of soil formation, particularly rice soil formation, is directly related to redox conditions. Under the reducing condition, the mineralization of organic nitrogen can lead ammonium nitrogen to be accumulated and nitrate nitrogen to disappear, and the effectiveness of soil phosphorus to be improved. The measurement of the oxidation-reduction potential of the soil is helpful for understanding the aeration and reduction degree of the soil. The common method for measuring the oxidation-reduction potential is a direct measurement method of a platinum electrode, and the method is based on that the platinum electrode is difficult to corrode and dissolve and can be used as a conductor. When the platinum electrode is in contact with the medium (soil, water). The soluble oxidizing or reducing agent in the soil or water will accept or donate electrons from or to the platinum electrode until an equilibrium potential, the redox potential of the system, is established at the platinum electrode. Since the potential of a single electrode cannot be measured, a cell is formed by a reference electrode (saturated calomel electrode) with the potential of the other electrode fixed, the electromotive force of the cell is measured by a potentiometer, and then the equilibrium potential established on the platinum electrode, namely the oxidation-reduction potential Eh value, is calculated.
