Kalkstet
As kalkstet ( calciphilous ) is defined as the property of some plants for normal growth ground limestone , so a certain amount of calcium carbonate concentration of the absorbed water, need.
In this context, the properties of lime-loving and lime-avoiding ( lime-fleeing ) plant species must also be mentioned:
- Lime-loving species prefer lime soils to other substrates.
- Lime-avoiding species are prevented from developing by a high concentration of lime. Most of the time, these plants generally need acidic soil.
Kalkstet must always be seen in connection with the region: Here, plants that are described as limestone in the north thrive on non-calcareous soils in the south, as otherwise good conditions exist here.
In Finland , for example, the common ash ( Fraxinus excelsior ) or the Bach speedwell ( Veronica beccabunga ) are considered limestone, but they can already be found in Switzerland in limestone-free areas.
