Answer 2

All soils contain mineralparticles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.



Relative size of sand, silt and clay particles

Soil is made up of different-sized particles. Sand particles tend to be the biggest. Clay particles are very small – less than 0.002 mm.

Soil texture

Soil is made up of different-sized particles. Soil texturerefers 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 feeling.

Soils are made up of different combinations of sand, silt and clay particles. Soils that are a mixture of sand, silt and clay are called loams.
