Agricultural Engineering Question:

A soil's texture, refers to its particle content, the size of particles, and how cohesive they are. Sandy soils have very large particles, for example, whereas soils with a lot of clay have very small particles. Both soil with a lot of sand and soil with a lot of clay can be problematic. Sandy soil permits air, roots, and water to move too freely while soil with a lot of clay does not offer enough room for air, roots, or water.
