The effect of soil physical and chemical characteristics and weather on redox potential was studied under field conditions. The soil patterns were taken from the topsoil (0-30 cm) and the subsoil (30-60 cm) during the growing period of the years 1996-1999. The values of redox potential during the whole observation period were higher than +200 mV, which reflected aerated conditions in soil. The values in the subsoil were always lower than in the topsoil. Redox potential was negatively correlated with moisture and pHKCl in the subsoil, and negatively correlated with maximal capillary capacity and bulk density in the topsoil. A positive correlation was found between redox potential and porosity, maximal and actual air content in topsoil of the Luvic Chernozem.
