Question

Short answer type question:
Distinguish between Red soil and Laterite soil.

Answer 1

Hint: The vast size of India, together with the richness in the natural environment of its various parts gives rise to a vast variety in the soil cover. The formation of different soil types, as we have already mentioned, depends mainly on the nature of the parent material, the environment, the general topography of the specific area and the behaviour of the species.

Complete Answer:
Red soil: On Archaean granite, gneiss and other crystalline rocks, the sedimentaries of the Cuddapah and Vindhayan basins and mixed Dharwarian group of rocks, these soils, also known as the omnibus group, have been formed. Their colour is primarily due to ferric oxides occurring on the soil particles as thin coatings, while the iron oxide occurs as haematite or hydrous ferric oxide, the colour is red and the soil gets a yellow colour when it occurs in the hydrate form as limonite. Typically, the surface.
1.Due to the weathering of igneous and metamorphic stones, red soil is formed.
2. It is extremely porous and less fertile, but it is fertile when it is deep.
3. Less crystalline, it is.
4. Owing to the presence of iron in it it is red in colour.
5. In parts of Tamil Nadu, Karnataka, Andhra Pradesh, Orissa and Jharkhand, they are present.

Laterite soil: First of all, these soils were analysed by F. Buchanan in 1905. Their name is derived from the word 'Later' in Latin, meaning stone. The soil is as soft as butter when wet, but becomes very hard and cloddy on drying. These are the typical soils characterised by seasonal rainfall in tropical regions (monsoonal conditions).
1. In the heavy rainfall areas of tropical India, it is created by the leaching process.
2. It is less fertile, and only grass grows abundantly on it.
3. It's all crystalline.
4. Due to the little clay and a lot of red sand-stone gravel, it is red in colour.
5. It can be found in the Deccan hills, Karnataka, Kerala, Orissa, Assam and Meghalaya.

Note: The red soils constitute the country's second largest soil community, covering an area of about 6.1 lakh sq. Km (18.6% of the country's area) from Tamil Nadu in the south to Bundelkhand in the north across the peninsula and Rajmahal hills in the east to Kachchh in the west. The field of lateritic soils is around 22 Lakh sq. Km (3.7 percent of the area of the country). The summits of the Sahyadris, Eastern Ghats, Rajmahal hills, Satpuras and Vindhyas are well formed.
