What is black alkali soil?

The term “Black Alkali” is used to refer to soils high in sodium carbonate content. Sodium carbonate buffers pH levels in soils above 9.0. At that pH level, soil organic matter (or, humus) in soils can dissolve and wick up to the soil surface giving salt deposits on the soil surface a dark brown to black coloration.

What is a dried up lake called?

Also known as a playa, a dry lake occurs as a depression with a dry lake bed where evaporation leads to drying up of a standing surface body.

What is an empty lake called?

An endorheic basin (/ˌɛndoʊˈriː.ɪk/; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through

What is Playa in geography?

What is a alkali pond?

An alkali sink is a salty basin land form. The term may also refer to a North American desert vegetation type (biome) characteristic of that landform. Rainwater drains to the basin and collects in areas where it cannot penetrate the soil due to a layer of clay or caliche, producing a pond or lake.

How is playa formed?

Playas occupy the flat central basins of desert plains. They require interior drainage to a zone where evaporation greatly exceeds inflow. When flooded, a playa lake forms where fine-grained sediment and salts concentrate.

Which soil is white alkali?

Saline soil (White Alkali) High toxic concentration of soluble salts in the rootzone. Soluble salts are Cl- and SO42- of Na, Ca and Mg.

Does salt Make soil alkaline?

Saline soils are mostly also sodic (the predominant salt is sodium chloride), but they do not have a very high pH nor a poor infiltration rate. Upon leaching they are usually not converted into a (sodic) alkali soil as the Na+ ions are easily removed.

What are alkali used for?

Uses of common Alkalis Sodium hydroxide is used to make paper, detergents and soap. Potassium hydroxide is used by farmers to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries.

Why are dry lakes flat?

A lake is formed from the water of rain, runoff, rivers and/or streams. When a change in climate occurs and there is a lack of sufficient rainfall, the rivers and streams that feed the lake dry up and the lake evaporates. Over thousands of years this can form a very flat surface on the lake bed.
