Manual classification of soils into textural classes with the USDA textural triangle is tedious. This computer program can perform the same task easier and faster. The algorithm is based on the fact that each point in the textural triangle represents a unique combination of sand and clay content. For a given textural class, all combinations of sand and clay content are bound by a polygon. Finding the textural class is equivalent to finding the polygon where a particular combination of sand and clay is located. Both a World Wide Web interactive version and a Windows 95 console program are available. On a 133 MHz Pentium microcomputer, the Windows version can classify 1000 soil samples in about a second.
