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 .
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 ...
The soil of the Blackland Prairies, from which the "blackland" gets its name, contains black or dark-gray, alkaline clay in both upland and bottomland areas. [4] Some western areas have shallow soils over chalk, while some soils in eastern areas are slightly acidic to neutral, grayish clays and loams over mottled clay subsoils (occasionally ...
Sporobolus airoides is a facultative halophyte, able to grow in soils with high salt concentrations. [2] This grass germinates best in warm, sunny, wet conditions, and it can easily move into saline soils such as those in alkali flats when the substrate is wet.
These grasses grow in wet environments, often in saline or alkaline conditions. They are native to temperate to Arctic regions of the Northern and Southern Hemispheres. They are native to temperate to Arctic regions of the Northern and Southern Hemispheres.
