Discussion on Phosphorus Forms and Transformation in Soil

The study of the existing principle of phosphorus in soil,transformation rules and the effectiveness of its transformed products can give us a guidance in fertilizing and developing new phosphorus fertilizer.The forms of phosphorus in soil generally include inorganic phosphorus(water soluble phosphorus,absorbed phosphorus,mineral phosphorus) and organic phosphorus.Crops mainly absorb inorganic phosphorus,its effectiveness varies with soil pH values.The need for phosphorus of plant is mainly absorbed from soil through root,therefore,the physical properties of soil definitely affect phosphorus forms,its effectiveness and supplying potential.The fixation and release of phosphorus forms take place with different soil conditions,such as pH value,organic matter,soil moisture,soil temperature,mineral component,soluble cations property,redox situations.
