Factors Affecting Measurements of Oxygen Diffusion Rate (ODR) with Bare Platinum Microelectrodes¹

The electrical resistance in the soil between the platinum electrode and the reference cell is very high in normal soils. Depending on the salt and water content, values from 5,000 to 20,000 ohms are commonly found. Drainage of the soil tends to increase the resistance, while the potential oxygen diffusion increases. However, the actual oxygen reduction will partly depend on the electrical resistance according to Ohm's law. This is discussed in the present paper and a method is suggested by which the current flow (ODR) can be corrected.
