It is defined by the relative amounts of sand (.05–2 millimeters particle size), silt (.002–.05 millimeters) and clay (less than 0.002 millimeters). Particles that are larger than 2 millimeters are rock fragments ... The quantity of variously sized pores—large, medium, small and very small—govern the important processes of water and air ...2. State the characteristics of sandy soil. Sandy soil essentially consists of small particles formed by weathering rocks. It is also very low in nutrients and poor in holding water, which makes it one of the poorest types of soil for agriculture. 3. Explain the significant features of silty soil. Silt has smaller particles compared to sand.Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
