WebPSYCHIC is a process-based model of phosphorus (P) and suspended sediment (SS) mobilisation in land runoff and subsequent delivery to watercourses. Modelled transfer pathways include release of desorbable soil P, detachment of SS and associated particulate P, incidental losses from manure and fertiliser applications, losses from hard standings, … Web3. Soluble P: the P export that is not sediment-attached or organic and traveling in overland flow 4. Tile P: the soluble P exported through subsurface drains • These four forms of phosphorus exported from fields are summed at the reach (or river) level and called “mineral” phosphorus and “organic” phosphorus as follows:
