As per ‘Soils of India, National Bureau of Soil Survey and Land Use Planning report: Publication Number 94’ which type of soil (order) is most abundantly available?

🔑Key Points:
 Inceptisols
-Inceptisols are soils of relatively new origin and are characterized by having only the weakest appearance of horizons, or layers, produced by soil-forming factors.
-They are the most abundant on Earth, occupying almost 22 per cent of all nonpolar continental land areas.
-They are usually arable with appropriate control of erosion or drainage.
-Inceptisol soil profiles give some indication of clay minerals, metal oxides, or humus accumulating in layers, but such accumulation is not sufficient to classify the soil into an order defined by characteristic surface or subsurface horizons.

🔴Additional Information:
Alfisols
-The Alfisols are soils characterized by a clay-rich horizon produced by illuviation and high base status.
-They are moderately leached soils that have relatively high native fertility.
-Alfisols are primarily found in temperate humid and subhumid regions of the world.
Aridisols
-Aridisols are CaCO3 containing soils of arid regions that exhibit subsurface horizon development.
-They are being dry most of the year and limited leaching.
-Aridisols contain subsurface horizons in which clays, calcium carbonate, silica, salts and or gypsum have accumulated.
Mollisols
-Mollisols are the soils of grassland ecosystems.
-They are characterized by a thick, dark surface horizon.
-This fertile surface horizon, known as a mollic epipedon, results from the long-term addition of organic materials derived from plant roots.
