Bangar/Bangad/Bhangar (Hindi: बांगर) areas are beyond the floodplains, [2] that lie more upland, and compared to Khadar it consists of older alluvial soil which is higher in sandy loam content. [4] Bangar areas are less prone to flooding but are usually more sandy and less fertile as well. [5] [6]
A large number of small and usually seasonal rivers flow through the Terai, most of which originate in the Sivalik Hills. The soil in the Terai is alluvial and fine to medium textured. Forest cover in the Terai and hill areas has decreased at an annual rate of 1.3% between 1978 and 1979, and 2.3% between 1990 and 1991. [2]
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil. Soil measuring and surveying device
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
Also known as regur soil, black soil is ideal for growing cotton and is known as black cotton soil. They are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents. [1] The black soils are made up of clayey soil, well known for their capacity to hold moisture.
Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals.
Kankar or (kunkur) is a sedimentological term derived from Hindi (and ultimately Sanskrit) which is occasionally applied in both India [1] and the United States to detrital or residual rolled, often nodular calcium carbonate formed in soils of semi-arid regions. [2] It is used in the making of lime and of roads. [3]
In terms of soil chemistry, it places particular emphasis on plant nutrients of importance to farming and horticulture, especially with regard to soil fertility and fertilizer components. Physical edaphology is strongly associated with crop irrigation and drainage. Soil husbandry is a strong tradition within agricultural soil science.
