Why do you think the properties of different soils are important for growing crops?​

All soils contain mineral particles, 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.
