Webnutrient transport to water resources, knowledge of the major mechanism of transport is needed. This requires information on the nutrient properties, the source(s)/availability of the nutrient, and the soil and climatic conditions that exist. A system may include a combination of in-field and off-site practices. Hydrology 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.
