The Soil organic matter level is at 2% to 4%, no barrier layer between paddy field and dry farm’s effective soil depth is beyond 60 cm. The cultivated land is of great production potential. But there is also some obstacle factors which affect cultivated land’s quality.1.The heavy soil makes up 71.9% of paddy field with an area of 4191.5 hm2 and 90.5% of dry farm with an area of 2612.1 hm2.2.The soil with lower pH than 5.5 makes up 33.7% of paddy field with an area of 1962.6 hm2 and 32.8% of dry farm with an area of 945.7 hm2.3.The organic matter content has a downtrend and is at 2% to 3%.4.
