For example, a soil having course sand predomi- nating is a couirse textured soil, whereas one having much clay is re- garded as fine textured. Meanings of Texture and Structure Compared.—Texture should not be confused with soil "structure" which means the arrangement of the soil grains (Fig. 6), or which describes the rela- tion of the soil particles to each other. It is important to remember that the soil components do not form a mere casual mixture in which every particle remains separate from every other particle.
