Soil Erosion 3 Typas

Soil Erosion 3 TypAs we go about our daily lives one of the things we don't about is soil. To use it is merely the dirt that is accumulated after a hard day at play for both children and adults. Soil is much more than that. Soil is the foundation that nourishes plants, animals and crops that humans need in order to survive. It's no wonder that the erosion of soil is a big concern to farmers and also to conservationists. They both understand that our lives would be harder if there were no soil or if the soil was limited. One of the biggest threats to soil at this point is erosion. It can be described as the wearing a way of something over a period of time. The amount of damage depends on the object being eroded, the force of the erosion and how long the erosion has taken place.

Soil can either be tightly compacted or it can be lose. The easiest soil to erode is the loose soil or sediment. The three types of erosion are wind, water and sheet. Wind erosion picks up the loose sediment and carries it from the farmland to another location. During this transfer precious nutrients are lost making it more difficult to grow crops. Farmlands are not the only places that are affected; those areas with high winds and little vegetation are also subject to this problem. The best way to combat wind erosion is to create natural barriers such as trees. They disrupt the air flow. Water erosion is very common and can cause two distinct problems: top and subsoil erosion.

When it rains there's a guarantee that topsoil is being washed away by the rainwater from one location to another location. Also, while the water is seeping into the ground-soil, it can carry off subsoil to a different location as well. This weakens the topsoil making it ripe for collapse. The more vegetation that is present the less topsoil and subsoil is taken away. Also, drainage ditches and flood walls are helpful also. Lastly, sheet erosion occurs when the thin layer of soil across expanses of land devoid of vegetation begins to move at the same time. The best solution would be to plant more vegetation (Fu-Berlin.de 2007).

Soil erosion is a serious problem just like global warming and deforestation. We as human beings are responsible for the planet that we live on and we need to take measures to preserve it.
