P and N content of surface and subsurface water flows in limestone soil
Introduction Pathways for P & n transport from soil to water bodies include overland flow,interflow and vertical flow.While a distinction can be drawn between infiltration excess and saturation excess overland flow,in practice they can be difficult separate.Likewise,interflow,which describe the lateral movement of water that has infiltrated the soil,but has not drained to groundwater,may emerge down slope and become indistinguishable from inter and overland flow.Ground water may also rise to the surface in places and merge with overland flow.Water moving by these pathways acquires nutrient by physical detachment of soil particles and by dissolution of soluble constituents.
