Particle-size distribution is a fundamental soil physical property, which may be used as the basis to determine other soil properties such as water retention characteristics.Describing soil particle-size distribution by parametric models has various advantages.In the present study, suitability of five parametric models is evaluated based on the data of particle-size analysis of 300 samples of three different type soils collected at Fengqiu Experimental Station, Chinese Academy of Sciences.Results indicate that the four-parameter Fred4P model shows the best representation of particle-size distributions of the three types of soils.The three-parameter Fred3P model and MLog model produce comparative results for silty clay loam and silt loam soils, but results not as good for sandy loam soils.Gomp model is even worse than Fred3P and MLog models in calculation error.The two-parameter MVG model yields the largest errors among the five models, and therefore is not suitable for describing soil particle-size distributions in Fengqiu area.
