The limitation of available phostosynthate for absorption and fixation of nitrogen occures from flowering stage in which the soybean forms the insufficient phostosynthate to the roots and nodules. Soil environments such as soil moiture condition, soil bulk density and soil acidity limit also the nitrogen nutrtion through their effect on the development and fuction of root and nodule.
