This study was carried out to find out basic data of the various cropping systems controlling the soil environment by analysing the historical literature, the changes of cropping system and the expected income of cropping system of the upland crop. The results were summerized as follows ; 1. According to the literature of 'Gumyangjoprok' and 'Sanlimgyungjae', published on 15 to 16 century in Korea, the cropping system of barley, soybean, red bean, and millet, etc. was done together both the 'kunkyong' and 'kanjong'. 2. Since 1970s the staple food grains had been self-sufficient and the setting up of the rice seedbed became faster. However, the cropping system of the rice after barley was rapidly fallen from 83.7% to 4.0% in 1990s. Furthermore, the food production and the rate of arable land utilization were also rapidly fallen. 3. The most prospective cropping system is considered the soybean after barley, and root & tuber crops considering with the soil environment. 4. The expecting income of cropping system ranged from 940,000won to l,970,000won per 10a but that of barley after soybean cropping for 610,000won, and that of barley-after mung bean cropping for 613,000won. 5. The maintenance and the preservation of agricultural environment shall become positive by practicing the Integrated Nutrients Management(INM), and the Integrated Pest Management(IPM) with control using of fertilizer and pesticide presenting the excessive loads to the soil environment.
