Spatial distribution of diuron sorption affinity as affected by soil, terrain and management practices in an intensively managed apple orchard

► Mid-infrared spectroscopy successfully used to predict diuron sorption affinity. ► Total organic carbon, pHw wetness index and slope determined the distribution of diuron sorption. ► Management practices altered distribution of soil and diuron sorption. ► Sod strips in the orchard alley increased the capacity of soil for diuron sorption.
