Test: Soils of India- 2

Mountain soil is most suitable to grow fruits like apples, pears, peaches and plums

Alluvial soil is found in the regions of Indo-Gangetic plains, Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal, Assam as well as in the northern parts of Gujarat. Alluvial soil is formed by depositions from surface water and thus is also known as depositional soils.

The substances which are added to the soil in the form of nutrients for the healthy growth of plants are called manure and fertilisers. Soil supplies mineral nutrients to the crop plants. These nutrients are essential for the growth of plants. In certain areas, farmers grow crop after crop in the same field.

Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. Therefore, most living things on land depend on soil for their existence. 

In short, soil is a mixture of minerals, dead and living organisms (organic materials), air, and water. These four ingredients react with one another in amazing ways, making soil one of our planet's most dynamic and important natural resources. Soil is used by people in numerous ways.

Soil is the top layer of most of our earth. Soil is partly made up of decaying plant or animal remains. These are called organic matter or humus and contain the living and once living components of our soil. Soil mostly contains pieces of disintegrating rocks or inorganic matter, water, and air.

If water freezes in a crack in rock, the ice can eventually break the rock apart. Because of these powerful properties, ice is very important in the processes of weathering, where rocks are broken into smaller bits, and erosion, where rocks and earth are washed or moved to other locations.

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. ... Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

black soils known locally as regur. After those the alluvial soil is the third most-common type. Also significant are the desert soils of Rajasthan, the saline soils in Gujarat, southern Rajasthan, and some coastal areas, and the mountain soils of the Himalayas.

Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water.
