Soils usually become salinated by irrigation from bore water or others waters containing small amounts of salt. The water evaporates and the salt is left behind; over time, the salt builds up and blocks the roots of the plants so no more water can be absorbed. This process is called "osmosis."
Black soils, also known as regur soils, have a high clay content which gives them self-ploughing quality. When these soils get wet, they swell and become sticky, creating cracks as they dry out. This expansion and contraction process helps in breaking up the soil, effectively ploughing itself.
Problem soils include saline soils, sodic soils, acidic soils, and compacted soils. Reclamation methods vary depending on the type of problem soil but can include adding soil amendments like gypsum for sodic soils, lime for acidic soils, and organic matter for compacted soils. Drainage improvement and crop rotation are other common strategies for reclaiming problem soils.
In Alabama, you can find a variety of soils such as sandy soils, clay soils, loamy soils, and peaty soils. The dominant soil types in the state include Ultisols, Alfisols, and Inceptisols. These soils vary in their characteristics and suitability for different types of crops or land uses.
No, sandy soils have higher permeability than clay soils. Clay soils have smaller pore spaces which restrict water movement, while sandy soils have larger pore spaces that allow for more rapid water drainage.
Yes, soils that are formed directly from the weathering and decomposition of underlying bedrock are referred to as residual soils. These soils typically retain similar properties and composition to the parent rock from which they originated.
0Tubewells help treat the salinated soil by bringing down the water table as it sort of sucks up water from underground. This extra water is then flushed down the affected area. It carries the salt, which is now diluted, to canals and rivers. The area does not have a layer of salt on it anymore and the water table is also lowered to prevent salination from occuring again.
the ions react with alkaline soils and produse atoms.

De-salinated sea water is pretty tasty, and some say the best water.
Gley soils have very poor drainage and nutrients don't move well through the soils. Also gley soils can easily become waterlogged and there can be a lack of oxygen through the soil.

Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.

Water becomes saline when it dissolves minerals and salts as it flows through rocks and soil. These minerals include sodium, chloride, magnesium, and calcium, which contribute to the salinity of water. Additionally, water bodies can become saline due to evaporation, leaving behind dissolved salts.
No, sandy soils have higher permeability than clay soils. Clay soils have smaller pore spaces which restrict water movement, while sandy soils have larger pore spaces that allow for more rapid water drainage.
North India is mostly made up of alluvial soils, but there are also mountain and submountain soils, teral soils, grey and brown soils, and desert soils.
