Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

Tutor: Date: Foundation Engineering Soil exploration obtains information about the subsurface parameters and conditions at the proposed Soil exploration as part of site investigation. In general‚ it deals with determining the suitability of the site for proposed construction. This consists of determining the profile of the soil deposits at and near the site. It mainly consists of taking the soil samples and checking the engineering properties of the soil and testing it in Situ. It then gets to

Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone has a

A Biome is all of the life zones‚ all plants‚ animals‚ and other organisms‚ as well as the physical environment in a particular area. A biome is characterized by its plant life‚ which is determined by its location. For example‚ northern coniferous forests exist in sub-arctic portions of North America and Asia‚ but further north‚ the conditions are simply too harsh and the season too brief for trees to grow. Instead of trees‚ the short vegetation of the tundra thrives in these areas. The same occurs

Causes Consequences Solutions Soil Erosion Water‚ wind‚ and people. (Miller‚2005 p.279) ●Soil erosion has two major harmful effects. One is loss of soil fertility through depletion of plant nutrients in topsoil. The other harmful effect occurs when eroded soil ends up as sediment in nearby surface waters‚ where it can pollute

Soil texture is related to a number of important soil characteristics such as water holding capacity‚ soil drainage‚ and soil fertility. In order to make this lab work to our own convenience we will use soil from our nearby area. This project was conducted to specify what type of soil there is in the area and what it can be used for.
