Role of soil in agriculture and its formation process.
Soil is usually the upper layer of Earth in which the growth of most plants takes place. Soil is characterized as a ‘hot bed’ which is a mixture of minerals, air, water, insects, worms, and billions of bacteria.
Soil is the most important aspect of agriculture and also the main source of nutrients needed for the growth of plants which feed us. It takes approximately 500 years to generate 2.5 centimeters of soil in a dried up or parched area.
