These studies were carried out to investigate the effects of rice straw on microflora in relation to nitrogen metabolism in submerged soil. In the submerged soil applied with rice straw the value of Eh lowered. pH was higher in the upper than in the lower layer. The content of iron(2) in submerged soil increased while that of ammonium nitrogen decreased when rice straw was applied and nitrate-nitrogen was hardly detected during the rice cultivation period
