Phosphorus Basics – The Phosphorus Cycle
nmsp.cals.cornell.eduWater carries away particulate (soil-bound) P in eroded sediment, as well as dissolved P from applied manure and fertilizers. Erosion control practices decrease P losses by slowing water flow over the soil surface and increasing infiltration. Leaching Leaching is the removal of dissolved P from soil by vertical water movement. Leaching is a
