Types of Agricultural Grasslands

However, in reality unless action is taken a number of weed species build up over the years. It may then have to be ploughed up and re-seeded. Typical weeds are docks, nettles, thistles and Couch Grass. All of these can make significant inroads into the crop yield. In lower yielding grasslands, dandelions and buttercups may also be present.

That is, one which will not affect grass. Despite this, the field may have to be re-seeded to re-establish the dominance of PRG. Whilst the field is being ploughed, cultivated and re-seeded, it is out of production. It is only when the crop has become established, that the farmer can use the grass for grazing or silage

These include the intensity of the fertiliser regime, together with the make-up of the species in the sward, as well as the harvesting and grazing of the grass. Soil type and topography also have a great influence on the type of grassland. The wetter and milder parts of Britain include the counties of Cornwall, Devon, Somerset and parts of Dorset. These are typically, the more productive grassland areas in Britain.
