it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils.

In chalk grassland, the plants can vary from very tall to very short. Quite tall grasses can be found in North American tallgrass prairie , South American grasslands, and African savanna . Woody plants, shrubs or trees may occur on some grasslands—forming savannas, scrubby grassland or semi-wooded grassland, such as the African savannas or ...
Plants on calcareous grassland are typically short and hardy, and include grasses and herbs such as clover. Calcareous grassland is an important habitat for insects, particularly butterflies and ants, [ 2 ] and is kept at a plagioclimax by grazing animals , usually sheep and sometimes cattle.
