archive.lib.msu.eduThese groups are called textural class names and are obtained byap-plying the particle size analysis to a textural triangle (Figure 1). Thus a soil which contains 40% sand, 40% silt and 20% sand would be called a loam soil. Table 2 lists several tex-tural class names and a typical particle size distribution for each. Some confusion occurs ...

www.uwsp.eduTexture can be done by textural analysis. The procedure for textural analysis is easy. Once this procedure is complete, the Soil Texture Triangle can be used to determine the texture type of the soil sample. Soil texture is directly related to the percolation rate of a soil in the size of air spaces and surface area of the soil particles.

web.extension.illinois.eduFigure 5: USDA Textural Triangle Figure 6: Relative Sizes of sand, silt, and clay In using the triangle, the following procedure is recommended: Assume the sample of soil contains 15 percent clay, 70 percent silt, and 15 percent sand. First, consider the clay. The base line at the bottom of the triangle is 0 percent clay.
