which is a flow that occurs through permanent gaps in the field, and may develop more during dry seasons [32]. The creation of preferential flow does not require certain conditions such as the intensity and duration of rainfall or the permeability and saturation conditions needed to create surface runoff [33]. It should also be noted that preferential flow reduces the contact time between the soil and the infiltrating water, further contributing to the transfer of phosphorus to the drains. Even though subsurface soils have a high absorption capacity, preferential flow can still result in the transfer of phosphorus from these soils to the drains.
