The texture of the soil depends on the constitution of?

The texture of the soil depends on the constitution of sand, silt and clay. These are the three main types of soil particles, and their relative proportions determine the texture of the soil. Soils that have a high proportion of sand particles tend to have a coarser texture and good drainage, while soils with a high proportion of clay particles have a fine texture and hold onto moisture. Silt particles are intermediate in size and give the soil a smooth, velvety feel. The combination of these three types of particles creates different textures and affects the soil's ability to retain water, support plant growth, and more.
