Abstract:
Today, soil erosion is considered as a natural disaster that affects direct or indirect many countries. It isn't thought merely soil loss. Along with soil loss, nutrients, organic matter of soil and wildlife disappear, at the same time it is observed that increasing the global warming and flooding. Besides these events don't only influence negatively the ecosystem but also it affects human life. Because 99.7% of food stuffs is provided from soil. In the face of disaster many techniques are used in all around the world and unfortunately these techniques are inadequate. This review reveals that what is the size of erosion in world and importance of using as a method of the forage plants on erosion control comparison of other method. It is known as true that there is inverse proportion between rates of plant cover and erosion intensity. The advantages of forage plants are cheaper and easy implementing, results of applications can be seen in short time as per other methods. Thanks to forage plants can grow in conditions of extreme soil and climate, they are unique plants for erosion control. Therefore, these plants can be easily used uncultivated erosion areas, fallow lands and as second crops to be summer and winter output in agriculture lands. Additionally, they develop structure of chemical and physical of soil and capacity of water hold is increased. On the other hands forage plants constitute basis of livestock sector. If we develop using the forage plants for erosion control also feeds of animal and vegetal will be increased.
