Answers
Answer:
Khadar is new alluvial soil. Bhanger soil is found away from the river. Khadar is found near the river basin. Bhangar is less fertile.
Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
Deccan Plateau is made up of lava, due to the volcanic fissure erruption. The soil in this area is the weathered form of this lava rocks only. And this is the reasoleaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. ... As water from rain, flooding, or other sources seeps into the ground, it can dissolve chemicals and carry them into the underground water supplyn of their black color. It is largely called Black soil or regur soil.
Red Soil and Yellow Soil
These soils are generally found in the Western Ghats, Odisha and Chattisgarh. The clay form of red soil is nutrient rich and viable for forestation. However coarse red or yellow soil has been completely leached of all its nutrients and is not fertile
The soil is one of the important resources of our country, as the fertile soil helps us in producing many crops. This serves the food requirements not only within the country but also in other parts of the world. Although it is not the same at every place on the earth. The types of soil of a place are determined by climate, landscape, and vegetation of that place. Soil also depends on the time of its formation.
Explanation:
ANSWER
Khadar(New) Bhangar(Old)
1. The khadar soils are found in the low areas of the valley, bottom of a valley which are flooded every year. The Bhangar soils are found in higher reaches, about 30 m above the flood level.
2. These soils are finer in texture. These soils are coarser in texture.
3. The khadar is light in colour and is composed of newer deposits. 3. The bhangar is composed of lime nodules or kanker and has a clayey
