This study was carried out to investigate the soil chemical and physical properties by annul variation and yield properties according to cropping rotation system of paddy field which was cultivated rice and soybean of each 1 year by turns, each 2 year by turns, 1 year of rice and 3 years of soybean and 4 years of soybean continuously. This study was conducted for 3 years from 2002 to 2004 in National Institute of Crop Science (NICS), Korea. Study was controlled by Shinpaldal 2 of midmatured species, sow a field with soybean by 60×15 cm in 27 May.
