In this article, we will explain on the statement,

“Soil which forms the uppermost layer of the land, is the most precious of all resources,”

because it supports the whole life system. It contains things like sand, silt, clay, air, and water. Soil also has nutrients that plants need to grow.

Different places have different types of soil. Some soil is rich in organic matter, which makes it fertile and good for growing crops. Here are some major types of soil:

1. Red Soil:

Found in plateau and lowland areas like eastern Bihar, Madhya Pradesh, Jharkhand, Chhatisgarh, Odisha, Kerala, Karnataka and Andhra Pradesh. Here the rainfall is between 100-300 cm/year and the temperature remains above 22°C. This soil supports rainforests and grasslands. It’s good for growing crops like potatoes, bananas, pineapples and rubber.
