Abstract: Effect of long-term located fertilization on spatial distribution characteristics of phosphorus in vegetable soil was studied. The results showed that the contents of total P and available P were all decreased with the depth increasing in soil profile and in the same soil layer, the content of available P in treatments with organic fertilizer was higher than in treatments with no organic fertilizer. Phosphorus activation coefficient and the content of organic P in treatments with organic fertilizer were significantly higher than in treatments with no fertilizer and no organic fertilizer in 0~60cm soil layer. Accumulating of phosphorus and long-term applying organic fertilizer were leading factors of making phosphorus move downward.
