Mesotrophic Grasslands In The British National Vegetation Classification System
The mesotrophic grassland communities in the British National Vegetation Classification system were described in Volume 3 of ''British Plant Communities'', first published in 1992, along with the calcicolous grassland communities and the calcifugous grasslands and montane communities. In total, 13 mesotrophic grassland communities have been identified: * two communities in which False Oat-grass is the characteristic grass species (one of these, community MG1, is widespread throughout Britain; the other, MG2, is confined to northern England). * four communities of well-drained permanent pastures and meadows, two of which ( MG5 and MG6) are widespread and the other two (MG3 and MG4) more localised * a single community ( MG7) covering a variety of widespread types of Perennial Rye-grass long-term ley * three widespread communities associated with poorly drained permanent pastures ( MG8, MG9, MG10) * three grass-dominated inundation communities, one of which, MG13 The MG 13 (sh ...

Mesotrophic Soil
Mesotrophic soils are soils with a moderate inherent fertility. An indicator of soil fertility is its base status, which is expressed as a ratio relating the major nutrient cations (calcium, magnesium, potassium and sodium) found there to the soil's clay percentage. This is commonly expressed in hundredths of a mole of cations per kilogram of clay, i.e. cmol (+) kg−1 clay. See also *Mesotrophic lake The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be ind ... Types of soil {{Ecology-stub ...

Perennial Rye-grass
''Lolium perenne'', common name perennial ryegrass, English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world. Description The plant is a low-growing, tufted, hairless grass, with a bunching (or tillering) growth habit. The leaves are dark green, smooth and glossy on the lower surface, with untoothed parallel sides and prominent parallel veins on the upper surface. The leaves are folded lengthwise in bud (unlike the rolled leaves of Italian ryegrass, ''Lolium multiflorum'') with a strong central keel, giving a flattened appearance. The ligule is very short and truncated and often difficult to see. The small white auricles grip the stem at the base of the leaf blade. Leaf sheaths at the base are usually tinged pink and hairless. Stems grow up to 90 cm. The inflorescence is unbranched, with spikelets on alternating sides edgeways-on to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
