Properties of soil
All soil contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structures is made up of different-sized particles. Soil texture refers to the size of the particles that make up the soil and depends on the proportion of sand, silt and clay-sized particles and organic matter in the soil. Sandy soils feel gritty when rubbed between your fingers. Silts feel smooth – a little like flour. Most clays are sticky and mouldable. If you’ve ever used pottery clay, you’ll know the feelinge, porosity, chemistry and colour.
