All the soils are made up of water, organic matter, air, and the mineral particles, but the combinations of all these elements determine the soil’s texture, colour, and porosity. This will help the people to identify the fertility soil.

Explanation:

  • Soil’s structure referred to the size of the particle which made the soil. Soil texture is very helpful to understand whether the soil is free from draining, how easy to grow plants and how much soil can hold water.
  • Soil’s porosity means the pores which are present in the soil. Pores are very helpful for the movement of water and air through the soil. Healthy soil will have many pores in them.
  • The colour of the soil can vary from black to red to white. The source of the soil colour is from iron and organic matter. The topsoil will be dark due to the presence of organic matter. The single colour indicates that the soil is very drained.
