摘要：

A simple modification of the Day hydrometer method is suggested for routine textural analysis. The simplified method requires no calibration, graphs or tables and uses a weighted average of the 1.5-hour and 24-hour readings to determine the clay fraction. The hydrometer scale reading error contributes more error than any other single parameter. -from Authors
