ABSTRACT
ODR was calculated for the soil water extracts prepared from freshly taken soil, wet soil stored in plastic bags and air dry soil. ODR in KCI solution was used as reference. ODR recorded for the extracts obtained from freshly taken soil was lower than for the extracts prepared from the stored soil samples. This indicates that for ODR measurements fresh soil should be investigated.
