In a soil triangle, what is usually found on the left side?

In a soil triangle, the left side represents the proportion of clay in a given soil sample. The soil triangle is a visual tool used to classify soil based on the relative percentages of sand, silt, and clay it contains. Clay particles are the smallest in size and contribute to the soil's texture and moisture retention properties. By locating clay on the left side, the soil triangle clearly demarcates the areas where different textures, such as clay, loom, sandy clay, and others, can be found based on the varying relationships of the three particle sizes. Understanding this classification system is essential for soil management and agricultural practices, as it informs decisions regarding irrigation, fertilization, and crop selection.
