LATERAL VARIATION IN THE CONCENTRATION OF CHLORSULFURON RESIDUES IN A SOD-PODZOLIC SOIL

Lateral variations in the concentration of chlorsulfuron in a Sod-Podzolic soil were studied. The distribution of chlorsulfuron in the soil was found to follow the normal distribution. It is demonstrated that the lateral distribution of residual amounts of a herbicide in the soil can be used to determine the level of error that is required in mathematical models used to evaluate the degradation of the herbicide, and in planning the number of samples required and the number of parallel determinations in each sample.
