Erosion

Erosion is one of the big problems we have in the environment. There are lots of different types of erosion but on the farm we have three main types; rill, sheet and gully erosion. We have a lot of conservation projects that we run to repair the soil and to avoid erosion.
In this photos you will see on of the projects in the Springbuck flats that we want to enhance plant growth in soil that suffers from sheet erosion.
The way we deal with soil erosion is a very cost effective way and is called branching. The first thing we do is to go out to the site and assess the problem and log it on the GPS. We do planning and decide what to do then we go and cut branches from Sickelbush or Acacias and put then on the treated area then we can use grass and other plant material. This way the top soil isn’t going to get blown away and all of the seeds that is taking a ride with the wind in going to get caught in the branches and new grass will grow there. This helps also that the rain drops don’t compact the soil as much.
