Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral

O horizon/Humus is the decomposing plant matter. A Horizon/Topsoil is the mixed humus and leached mineral soil. E Horizon/ Zone of leaching‚ there is less humus‚ minerals resistant to leaching. B Horizon/ Subsoil the accumulation of leached minerals like iron and aluminum oxides. C Horizon/ Weathered parent material which has partially

Soil and Vegetation Regions Assessment 1. Describe the vegetation region in your area. Rate how natural the vegetation is on a scale of 0 (not natural) to 5 (very natural). Give a reason for your rating. Currently living in Brampton‚ the vegetation regions remains a mixed forest. Mixed forests are vegetational transition between coniferous forests and broad leaved deciduous forests. Common trees are ash‚ hemlock‚ oak‚ birch‚ maple‚ pine‚ fir‚ spruce‚ and cedar can be found in the mixed forest.

agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater to the surface. Water would not ‘pool-up’ either so root rot could be prevented.

present. This can be justified by the fact that the sample was taken just as the dunes started on the embryo dune. Therefore reasons for no vegetation is that there are extreme conditions at this point; very high pH values (8+); rapid drainage; no humus; high wind speed and lots of salt spray‚ all of which make it almost impossible for vegetation to grown and the colonies‚ furthermore this dune can be disappear as quickly as they form.

and tiny rock particles are then deposited by the agents of erosion. The accumulation of such sediments over the ages forms soil. Eventually‚ the plants that grow on the soil‚ shed their leaves which decay to form the topmost layer of soil called ’humus’. India is primarily an agricultural country. The success of agriculture depends upon the fertility of soils. The soils of India are classified into the following main groups depending upon the rock cover and climatic conditions. The most two
