Question

laterite soil is developed in area with______
A. Low temperature and low rainfall
B. High temperature and low rainfall
C. Low temperature and heavy rainfall
D. High temperature and heavy rainfall

Answer 1

Hint: Topographically, Indian soils can extensively be distinguished into two primary sorts:
(a). Soils of peninsular India and
(b). Soils of extra-peninsular India.

Complete answer:
The word ‘laterite’ (from Latin letter meaning block) was first applied by Buchanan in 1810 to a clayey stone, solidifying on exposure, seen in Malabar. However, numerous creators/authors concur with Fermor’s limitation of this term to soils composed as to 90- 100 percent of iron, aluminum, titanium, and manganese oxides. As per a greater point of view, the laterite soil is shaped under states of high temperature and substantial precipitation with substitute wet and dry periods. As per Polynov, laterite soils might be “the final results of enduring given an adequately significant time-frame”. In the assessment of George Kuriyan, “It is presumably the finished result of decay found in areas of hefty precipitation, in excess of 200 cm” Such climatic conditions advance filtering of soil whereby lime and silica are drained away and soil wealthy in oxides of iron and aluminum mixes are abandoned. We have various assortments of laterite which have bauxite toward one side and an inconclusive
combination of ferric oxides at the other. Practically all laterite soils are exceptionally poor in lime and magnesia and inadequate in nitrogen. In some cases, the phosphate substance might be high, most likely present as iron phosphate yet potash is lacking. At certain spots, there might be a higher substance of humus.
So, the correct answer is Option D.

Note: Laterite and lateritic soils are generally spread in India and spread in a region of 2.48 lakh sq km. They are for the most part found on the highest points of Western Ghats at 1000 to 1500 m above mean sea level, the Eastern Ghats, the Rajmahal Hills, Vindhyas, Satpuras, and Malwa Plateau.
