Erosion =D

Soil Erosion is the removal of top soil through actions like weather conditions like rain,snow or wind,then you also get other natural causes like animals.Erosion is also caused by us humans.

Types of EROSION...

Sheet Erosion: At the 'Springbok vlaktes'

Rill Erosion: The "Dienspad".There's a lot Rill Erosion because of the vehicles.

Gully Erosion: At Tambuki,there's a ditch next to the road.

How can we control EROSION???There are different techniques...

• Branching: Place branches on the area where you want to protect it from animals crossing or eating it.
• Gabions: Baskets with rocks in them,to prevent the rocks from falling into the roads for example.
• Active seedling: Seeds from a fast growing indigenous grass can be planted. Their growth points are very close to ground level and they often form stolons and or rhizomes which are good at stabilizing the soil. Grasses survive in difficult conditions. They break the speed of runoff water and of raindrops and protect the soil against wind and this protects seed bank. The plant bases collect organic material that improves the nutritional status of the soil.
• Biomac Soil blankets: Natural degradable blankets are placed over the soil, which protects the soil and aids in seed production and grass growth.
• Correct farming methods: Contour farming is the correct way to plant crops. This method follows the natural life of the land, preventing excessive runoff.
• Stream bank protection: Wooden barrier is placed on the bank of a river to slow down the water and reduces the strength of the water.
• Stones: Stones and rocks could be packed to form walls, which check the flow of the water and trap soil.
• Windbreaks: Natural windbreaks can be planted using indigenous trees and shrubs in areas where erosion by wind is a main factor.
