What is land rehabilitation?
Land rehabilitation is the process or restoration of damaged land to its original state. The original source of damage, human or natural is not important in the long run; Although this affects the methods of rehabilitation. In most cases, the soil cannot be returned to its natural state. Because it is usually impossible to return the area to its exact original conditions, the rehabilitation of the land simply focuses on as much soil improvement as possible.
Land rehabilitation is not as simple as it may seem. Some things that seem to cause a lot of damage have a very small impact while other things are devastating. One of the biggest challenges of soil rehabilitation is to clean the poison from the ground. Many people created by man come up with poisons used for different things. Soil cleaning is a time -consuming and difficult business.
Natural disasters are usually on the list of things that damage landing for all their destruction, most natural inconsistencies have a very low impact on soil qualityy. As already mentioned, there is sometimes damage due to human intervention. For example, the flood can collect harmful chemicals from entering houses and factories, which then enter the water system.
forestry also has a very low impact on soil viability. While many people consider tree cutting harmful, it is not necessarily. Modern techniques of forestry selective cutting and plantings have minimized the impact of this industry on soil quality. Since forestry does not use harmful chemicals or causes deep disruption of soil, they also removed two common damage to secondary land.
Modern mining of open pit has a serious impact on the soil. The steps of soil rehabilitation related to this sector differ, but monitor the general order. First, they try to clean any harmful chemicals that may be ground or rocks from a place. They also fill holes with pure rocks and soil and, if possible,using the removed material. Finally, they turn the soil to natural state and vegetable natural vegetation. It can be a very long and exhausting process.
Agriculture is the main cause of soil rehabilitation. Farms often use deadly chemicals that can soak up local water supply. In addition, excessive irrigation increases the salinity in topsoil, causing it unable to grow. The solution of these two problems is the main part of the soil rehabilitation and there has been limited success. Modern farms have begun to move away from particularly harmful practices, but older farms remain a problem.
