Description Kresoxim methyl sorption in soils of five agro-climatic zones of India varied from 41.6% to 84.7%. Highest sorption was
recorded in organic carbon rich Almora soil. Isotherm parameters for linear and non-linear Freundlich and Temkin models
were almost same, whereas Langmuir parameter Q0,
for linear (1.60 to 9.434 μg g−1) and non-linear (8.48 to 17.129 μg g−1)
models were quite different. For isotherms optimization different error functions such as sum of squares error (SSE), root
mean square error (RMSE), Chi square error, hybrid fractional error (HYBRID) and average relative error (ARE) were
calculated. Lowest error function values were obtained for Freundlich isotherm in all the soils except inceptisol (Kolkata)
for which Langmuir isotherm gave the best fit. Statistical analysis using SAS 9.3 software and Tukey’s HSD test revealed
the significant effect (p < 0.001) of soil type on sorption. Sorption correlated positively with the organic carbon and clay
contents of the soil.
