Exception: the Ganga-Brahmaputra delta region is rich in humus. What types of crops are grown in alluvial soil? Dark brown or black color in soil indicates that the soil has a high organic matter content. If the water velocity decreases, finer particles (sand and silt) are deposited, while fine silt and clay particles are deposited by slow-moving water such as that found associated with deltas. Secondary colours, bleaches and mottles are also recorded. We learnt about the various ways to classify soils. Natural silty soil background: brown, gray and red Texture and colour: layered alluvial loams The topsoil is dark brown to brown loamy sand to fine sand loam with weak structure, and is apedal massive or single grained. LTD is the parent company of CIVILSDAILY IAS. these soils are very rich in chemicals like Potash, Phosphoric acid, lime and carbon compounds but are deficient in Nitrogen and humus. They are often referred to as transported or azonal soils. In this region the soil acidity is more related to the soils formation and its parent geology. Soil that has a high water content will have less air in the soil, specifically less oxygen. fertile soil deposited by water flowing over flood plains is called alluvial soil.Alluvial soil is the most widely spread and important soil.

Generally the old alluvial soil is very deep, brownish to yellowish brown with texture of fine loams to coarse loams and is slightly to moderately acidic. The alluvial soils are characterized by the absence of or very thin litter. These soils are airy and need irrigation for cultivation. With rain, lime and silica are leached away, and soils rich in iron oxide and aluminium compound are left behind(thus the reddish brown colour). These soils are poor in organic matter, nitrogen, phosphate and calcium, while iron oxide and potash are in excess. This will clear students doubts about any question and improve application skills while preparing for board exams. It covers about COLOUR: Soil colour is assessed in a moist condition using a Munsell Colour Chart (Munsell Colour Company, 1975) to assess the dominant colour.

Alluvial soils of the northern plains —> transported soils —> therefore lack humus —> lack nitrogen [That is why we need to use nitrogenous fertilisers in the northern plains!]. Gorbunov and Bobrovitskiy (1973) mention that it allows mineral identification based on external morphology, illustrated by an unconvincing image for alluvial soils. Alluvium, the material deposited by rivers, consists of silt, sand, clay, and gravel and often contains a good deal of organic matter. What is alluvial soil and where is it found?
