Physical Properties of Soil The soil properties that we can see or feel and are relatively more permanent than chemical properties are called physical properties of soil. Such properties are difficult to change. Soil physical properties include texture, structure, particle and bulk density, porosity, air and water content, consistency, colour and temperature. Soil Texture and its Significance It refers to relative proportions of the three primary soil separates (sand, silt and clay). Texture is important because it determines the ease of tilling the soil, the amount of aeration, water intake rates and water storage in the soil. It also influences soil fertility. For instance, a fine textured clayey soil is difficult to till, has poor aeration for good root growth, difficult to wet and difficult to drain but it can retain more nutrients and water. A coarse sandy soil is easy to wet, easy to drain and easy t
