). Inorganic or organic P, which has no valency changes during its biotic assimilation or microbial decomposition, is mainly removed through microbial and plant uptake ( Vymazal, 2007 ). Roots and rhizomes support rhizospheric microorganisms by providing

rainfall frequently occurs in spring and fall, which can induce flooding, especially in areas with poorly drained soils ( Kijne, 2006 ). Flooding affects soils by altering soil structure, depleting O 2 , accumulating CO 2 , inducing anaerobic decomposition
