Soil Constituents


Living things are broadly classified into plants and animals. Animals are seen as producers in the ecosystem. They manufacture food and store while other organisms depend on them directly or indirectly. To be able to do this effectively, plants need to grow in good soils. In today’s lesson, we will learn about soil and its constituents.

Meaning and types of soil

Soil is the topmost layer of the earth’s crust. It serves as habitat for some lower organisms. The soil is where the root of most plants are buried. It serves to hold the plant firmly to the ground. It is also the place where plants draw the nutrient they need to grow and produce food for animals. The water needed by plant too is gotten from the soil.

There are three types of soil. They are

  • Sandy soil
  • Loamy soil
  • Clay soil.

The best type of soil that supports plant growth and provides the right nutrient for plant growth is the loamy soil
