The soils of Assam are very rich in content of nitrogen and organic matter. The alluvial soils of the Brahmaputra and the Barak valley are highly fertile and are very much suitable for raising of varieties of crops round the year such as cereals, pulses, oilseeds, plantation crops etc. The well drained, deep, acidic alluvial soils of upper Assam with good proportion of phosphoric content are mostly suitable for the plantation. New alluvial soils occurring in the charlands of the Brahmaputra are most suitable for growing oilseeds, pulses and rabi crops. The alluvium of the plains offers excellent opportunity for cultivating rice and vegetable. The soils occurring in the upper reaches of the hill slopes are very suitable for horticulture.
