Clayey soils, also known as loams, are a type of soil composed of clay particles, sand, and silt. They are known for their high water-holding capacity and ability to retain nutrients, making them ideal for growing crops. Clayey soils are often used in agriculture and horticulture due to their ability to support plant growth. They are also used in construction, as they are strong and durable. Clayey soils are generally found in areas with high rainfall and moderate temperatures.
