Question

essay on soil and about red and black soil​

Answer 1

Explanation:

The black soils are made up of extremely fine i.e. clayey material. They are good for growing crops. Red soil: These soils are red in colour. These soils are not ideal for growing cotton.

Soil color does not affect the behavior and use of soil; however, it can indicate the composition of the soil and give clues to the conditions that the soil is subjected to. Soil can exhibit a wide range of colour; grey, black, white, reds, browns, yellows and greens. Varying horizontal bands of colour in the soil often identify a specific soil horizon. The development and distribution of color in soil results from chemical and biological weathering, especially redox reactions. As the primary minerals in soil parent material weather, the elements combine into new and colorful compounds. Soil conditions produce uniform or gradual color changes, while reducing environments result in disrupted color flow with complex, mottled patterns and points of color concentration.

Answer 2

Answer:

The black soils are made up of extremely fine i.e. clayey material. They are good for growing crops. Red soil: These soils are red in colour. These soils are not ideal for growing cotton.The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous. Thus, proper use of fertilizers and irrigation yields high production of cotton, wheat, rice, pulses, millets, tobacco, oil seeds, potatoes, and fruits.

Soil color is produced by the minerals present and by the organic matter content. Yellow or red soil indicates the presence of oxidized ferric iron oxides. Dark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil.Black soils constitute the food basket for many countries and for the world in general and are often recognized as inherently productive and fertile soils. They are extensively and intensively farmed, and increasingly dedicated to cereal production, pasture, range and forage systems.The differentiate between red and black soil given below:

Bajra, millet, potato, etc are some of the crops suitable to grow in Red Soil. The black soil provided fertile land with rich in humus. Black soil is rich in calcium, potassium and magnesium. Crops like cotton, oilseeds, tobacco, ragi and maize grow well in it.
