Alkali, or alkaline, soils are clay soils with high pH (greater than 8.5), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate , which causes the soil to swell ...
It tolerates alkaline soil, salt and sand. [4] The leaves accumulate salts which helps extract water from the soil when other plants cannot. [4] Salt is shed by dropping the leaves. [4] It can live in up to 30 ppm Boron in solution, compared to most plants which can tolerate only about 1-5 ppm. [4]
Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil acidity (or alkalinity) is the concentration of hydrogen ions (H +) in the soil. Measured on the pH scale, soil acidity is an invisible condition that directly affects soil fertility and toxicity by determining which elements in the soil are available for absorption by plants.
Calcareous grassland (or alkaline grassland) is an ecosystem associated with thin basic soil, such as that on chalk and limestone downland. [1] Plants on calcareous grassland are typically short and hardy , and include grasses and herbs such as clover .

Suaeda is a genus of plants also known as seepweeds [2] and sea-blites. Most species are confined to saline or alkaline soil habitats, such as coastal salt-flats and tidal wetlands. Many species have thick, succulent leaves, a characteristic seen in various plant genera that thrive in salty habitats (halophile plants).
Most vegetables are full-sun plants that require at least 8 hours of direct light to grow outdoors; however, plants like tomatoes generally need 16-18 hours of bright light to fruit inside.
