An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms. To identify, understand, and manage soils, soil scientists have developed a soil classification or taxonomy system. Shrubs such as rabbitbrush and greasewood, or even trees such as ash or willow, are common in the area of alluvial fans. Alluvial soil [43%] Alluvial fans can be very diverse habitats. 4)These soils contain adequate proportion of Potash, Lime and Alluvial soils as a whole are very fertile.

The most general level of classification in the United States system is the soil… Soil morphology is the study of the formation and description of soil types within various soil horizons. Alluvial deposits are usually most extensive in the lower part of a river’s course, forming floodplains and deltas, but they may form at any point where the river overflows its banks or where the flow of a river is checked. The scientific study of soil is called pedology. Loose sandy soils consisting of wind-borne deposits and riverine sands are found in the northern regions, although, in areas where there is a marked dry season, a dense surface layer of laterite develops, making these soils difficult to cultivate.

Answer: The chief region of Alluvial Soils in India is the Indo-Gangetic plain, where Alluvial Soils have been deposited mostly by rivers. The most important and widespread category of the soil is alluvial soil. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Q.19. Thus the great diversity of geologic materials, geomorphic processes, climatic conditions, biotic assemblages and land surface ages in the United States is responsible for the presence of an enormous variety of mineral and organic soils. Alluvial soils. The upper portion of the soil (0 to 9 m depth, borehole Y3) was totally weathered and transformed into Grade VI residual soil .The soils of this layer are clayey silt with smooth-textured soil particles, and the remnant parent rock is not observed. Coarse alluvial soil is more common in piedmont plains such as Duars, Chos and Terai. The work of Ramdas, L.A. and David, R.K.
