2. INTRODUCTION:
• Soil is considered to be an important natural resources.
• Plants grow on soil and animals depend on plants for their
food. Therefore all living being on earth depend on the soil
for their food.
• We depend on soil in many other ways: mud is used in
villages to make wall of the house, we make cloth from
plants like cotton and jute, which in turn need soil to live.
• There various types of soil like alluvial soil, black soil, red
soil, laterite soil, desert soil, mountain soil. In our upcoming
soils we’ll study in brief about them.
3. ALLUVIAL SOIL:
• The rivers of northern plain brings with them large
quantities of Silt or alluvium.
• this gets deposited on the land around the rivers. The
soil is very fertile and is called alluvial soil.
• It makes the Northern plains the most fertile regions of
the world.
• This sol is especially good for the cultivation of rice,
heat, sugarcane, jute.
4. BLACK SOIL:
• It is found in the central and north-western parts of the
southern plateau.
• W can found this soil in Maharashtra, Madhya Pradesh,
Andhra Pradesh, Gujarat, Karnataka and Rajasthan.
• It is formed from the lava that came out of volcanoes.
• It is very good for growing cotton and sugarcane.
5. RED SOIL:
• It is found in southern plateau regions.
• It is not fertile as red soil but can be made fertile by adding
manure in it.
• It is good for growing crops such as jowar, bajra and groundnut.
6. LATERITE SOIL:
• It is found in western Ghats and part of Tamil
Nadu.
• it is rich in iron and aluminum and is red in
color.
• It is good for crops such as tea, spices, coffee,
rubber and coconut.
7. DESERT SOIL:
• It contains mostly sand.
• It is found mainly in Rajasthan and Gujarat.
• Sandy soli can’t hold much water.
• It is, therefore not fertile.
8. MOUNTAIN SOIL:
• It is very rich in humus.
• Humus is the remains if dead plants and animals.
• The minerals present in the humus makes the soil
fertile.
• This soil is found in Himalayan region and I north-
eastern parts of India.
• This soil is appropriate for the growth of fruits such as
Apple, Pear, Peach and Plum.
