Discussion on the Soil Water Characteristic Curve of the Agricultural Soil in Shunyi,Beijing

Soil water content and the corresponding value of tension are obtained using centrifuges and was simulated by vG mode1 of soil samples from Shunyi in Beijing.According to the data tested by the parameters of the field soil physical properties,the characteristic of the soil moisture curve have been compared under the different texture,planting condition and depths.The results show that the soil texture and cultivation conditions have a significant impact on the soil moisture characteristic curve of the undisturbed soil.
