A preliminary investigation of physico chemical properties of agro-soil in Nanxiang, Fangtai, Jiading, and Malu Town in Jiading, Shanghai has been made by comparing 4 kinds of soils sampled from greenhouse, paddy field, orchard, and open-ground. The result showed that the soil texture in this district was silt (sandy) loam. The acidity of soil in the district was orchard> paddy field>open ground> greenhouse, mostly ranging from neutral to weak alkalescent except that the orchard was weak acidulous. Greenhouse soil was more alkalescent than others as its EC value was higher and its exchange sodium percentage was close to 5 %, having a tendency to be salinization. The cation exchange capacity of all the sites varied from 10 to 20 cmol(+)kg-1, indicating that the fertility hold capacity of Jiading soils was moderate. Nitrogen content in Jiading district was lower than that of the average amount in agro soil of Shanghai, except for the paddy field soil. Phosphorus and potassium was quite abundant and the content was above the average level, except for the open ground soil. Generally, nutrient content in Jiading paddy field soil showed good physico chemical properties and high nutrition level. Nutrition in greenhouse soil was also ample while the large amount of salinity was likely to cause the secondary salinization in greenhouse. Nutrition level in open ground soil was the lowest. Therefore, measures such as applying organic matter and planting rice could be taken to improve the soil quality and fertility.
