The texture triangle (Figures 1 and 2), sometimes referred to as the tertiary soil diagram, is used to plot the soil texture class. The soil texture worksheet answers this by giving information about how much fertilizer is needed to be applied. Soil is a medium comprised of soil particles, organic matter, water, air and living organisms, all of which are important to the overall health of the soil and the plants that grow in it. Although the texture by feel method takes practice, it is a useful way to determine soil texture, especially in the field.
