Gullies resemble large ditches or small valleys, but are metres to tens of metres in depth and width. When the gully formation is in process, the water flow rate can be substantial, which causes the significant deep cutting action into soil. 15. What environmental problems occur in temperate grassland? Few natural temperate grassland regions remain because most have been turned into farms or grazing land. This is because they are flat, covered with grass and have a rich soil. Overgrazing, ploughing, and excess salts left behind by irrigation waters harm temperate grasslands. Strong winds blow loose soil from the ground after ploughing, especially during droughts.

harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is an important type of aquaculture in some places. Maerl is commonly used as a soil conditioner. Factors incluencing soil microflora 1. Cultural practices (Tillage):Cultural practices viz. cultivation, crop rotation, application of manures and fertilizers, liming and gypsum application, pesticide/fungicide and weedicide application have their effect on soil organism. Ploughing and tillage operations facilitate aeration in soil and exposure of soil to sunshine and thereby increase the biological activity of organisms, particularly of bacteria. Crop rotation with legume maintains the favorable microbial population balance, particularly of N2 fixing bacteria and thereby improve soil fertility. Liming of acid soils increases activity of bacteria and actinomycetes and lowers the fungal population
other islands. It seems that the Celts mixed with the Iberian peoples who were already there. It is also possible that they drove many of the older inhabitants westwards into Wales, Ireland and Scotland where they were eventually assimilated2. Celtic Culture The Celtic tribes continued the same kind of agriculture as the Bronze Age people before them. But the use of iron technology and more advanced ploughing methods made them highly successful farmers, the Celts used ox-drawn wheeled ploughs and this meant that richer, heavier land could be farmed. Under the Celts Britain became an important food producer. It now exported corn and animals, as well as hunting dogs and slaves, to the European mainland. The two main trade outlets eastwards to Europe were the settlements along the Thames River in the south and on the Firth of Forth in the north. It is no accident the
