The need for food will increase by 59-98% from 2005 to 2050, and its global growth production has been achieved mainly through the intensive use of inputs such as pesticides and chemical fertilizers. Once released to the soil, sorption (represented by Kd values) and degradation are two governing processes that determine the distribution and persistence of pesticides. In spite of the huge dataset, the only apparent generalization is the high correlation between Kd and soil organic matter (SOM) content. This is because the SOM is the main adsorption site for pesticides. Seeking to normalize the experimental data and to access the pesticides mobility, the KOC value is calculated: Kd normalized by soil organic C content (C).
