The problem of soil resources.1. erosion and erosion by water. Many of the affected surface water directly to the soil surface are erosion, dropped the water depends on the strength and water runoff areas down.
Soil problems first. Erosion and erosion by water. A lot of water on the surface directly to soil erosion. Let slip the water was up to strength. And the area of water runoff down.
The soil resource 1. Erosion and erosion by water. A lot of water that affect ground surface directly is eroded the soil surface. To go by, it depends on the strength. And the area of water runoff down.
