WebThis is important for the transport of phosphorus and potassium. Root interception occurs when growth of a root causes contact with soil colloids which contain nutrients. The root then absorbs the nutrients. It is an important mode of transport for calcium and magnesium, but in general is a minor pathway for nutrient transfer. Webphosphorus concentrations increased while inorganic nitrogen levels were preserved. Dan Richter (Oak Ridge National Laboratory; personal communication) indicates that in his …

WebPhosphorus assimilation is a microbially mediated process, which is discussed in the section titled ‘Transitory immobilization’. Phosphorus is transported within the … WebPhosphorus is supplied to roots primarily by diffusion and root interception. Mass flow/bulk flow is the movement of nutrients to root surfaces through soil water movement. Mass flow to roots is driven by plant transpiration, however, mass flow is not a major pathway of P movement to plants.
