Question

Explain the importance of soil for plant growth.

Answer 1

Soil is the layer of earth that results from the degradation of the basement rock— also known as bedrock—due to certain physical, chemical and biological processes. It supports plant growth. It is a source for water and nutrients required by plants,
An important constituent of soil is its organic component, comprising dead and decaying leaves and parts of plants and animals. This organic material decomposes to form humus, which in turn determines the structure and fertility of soil( nutrient content). It is porous in nature and allows water and air to pass through.
