Soil can be classified into three primary types based on its texture – sand, silt and clay. Loamy soil contains equal amounts of the mineral components. First sandy soil allows for good drainage, Almost all crops will benefit from this as their roots will not drown. If more clay content is present, it is considered clay loam. of clay, silt, and sand and names such as sandy loam, silty clay, and clay loam are used to categorize soils based on the relative percentages of clay, silt, and sand (Figure 7-1).
