This soil is known as the poorest type of soil for agriculture and growing plants as they have very low nutritional value and poor water holding capacity. Clay has smallest sized particles(less than 0.002 mm) thus it has very less soil air due to small intermolecular spaces. Soil erosion is more common in areas that are not covered by trees or grass and. More than \(2/{3^{{\rm{rd}}}}\) of the soil is clay. Soil is classified into 4 different types based on the size of the particles it contains. Other types of soil are based on the percentage of particles, resulting in more compound types of soil: loamy sand, sandy clay, silty clay, etc. Swells and will become sticky when wet and shrink when dried. For example, a soil with 30% clay, 50% sand, and 20% silt is called a sandy clay loam. Apart from these, soils are also classified based on their colour- Red soil, Black soil and Brown Soil. This can cause the clay particles to form clumps, improving the soil structure and drainage. Convex Terrain (Ridge) - dry solid place to build. We get many useful things from forests.
