Abstract:soil samples from of 3 804 hm 2 farmland on Sanhu Farm in Hubei were tested. The results were as follows:the mean content of organic matter, alkaline hydrolysis nitrogen,available phosphorus and available potassium in tillage layer were 28 8 g/kg,118 42 mg/kg,7 02mg/kg,152 10 mg/kg respectively in 2000.Compared with the mean content in 1981,organic matter and alkaline hydrolysis nitrogen decreased 22 2 g/kg and 33 6 mg/kg with an annual decrease of 1 11 g/kg and 1 68 mg/kg respectively. Some ways improving soil fertility were suggested based on the results.
Keywords:soil nutrients  general investigation  Sanhu Farm
