title: Assessment of herbicide transport and distribution in subsurface environments of an orange field.
abstract: The demand for assessing both the variability of risk areas and the intensity of pollutant load rates on pesticide transferring to waters in China has been increasingly vigorous in recent decades. Therefore, to explore the transport of linuron with rainfall and irrigation in canopy-soil systems, an integrated pesticide transport modeling system has been selected and verified for simulating the three-phase linuron environmental fate in an orange field of the Three Gorges Reservoir (TGR) area. Results demonstrate that spatio-temporal distributions of linuron in surface soil primarily depend on its properties, rainfall, irrigation, and its applications; the peak levels of linuron in subsurface and deep soil are closely related to the cumulative and delayed effects. The findings may be used for policy supporting of soil-water-crop-pesticide management in an agricultural field of the TGR area.
