Once the particle-size fractions (sand, silt, and clay) are measured, a textural triangle such as the USDA triangle is used to classify the soil. The triangle is used by extending lines from the appropriate starting points, parallel to the side of the triangle, counterclockwise to the side where the line began. soil texture triangle, gradually skidded and ended up in a totally reshaped and extended code (over a 3 year period). Write down the name of your soil texture. Soil texture describes the proportion of three sizes of soil particles and the fineness or coarseness of a soil. One side of the triangle represents percent sand, the second side represents percent clay, and the third side represents percent silt. The software also allows to plot soil texture data in 2 different triangle geometries. } The average values of field capacity, wilting point and porosity are presented.
