My second graders in Missouri are learning about erosion and erosion control. This video gave them a real world example of what they have been learning. Thank you.
That is literally the best and simplest explanation of how to control water and erosion on a hill I have seen. I have been reading about jow to fix my issues with run off for so long and that just makes it so clear! Thank you
Madre cacao is also used for living fences here in the Philippines. You can occasionally chop and drop them for green mulch and they'll bounce back within a few months.
Excellent vid, thx. been using this technique below a few nice-sized trees to fight soil eroding on our wooded lot. You've inspired me to extend them further across the slopes. Best wishes. Good job.
The Gliricidia stakes and living plants are a good approach as using debris alone won't last long. An Australian study trying to reduce gully erosion compared stick dams like the debris you used, with rock dams, and found the rock damns, most of which were only one rock high, were much more effective long-term, and filtered the water along the way to rivers. There are a lot of examples of swales overflowing during heavy downpour and creating erosion on RU-vid. Making sure the overflow outlet of swales is wide enough to sheet excess water away slowly is important to reduce the creation of new gullys and erosion.
Thanks Craig for the info. Yes, the permanence of the line is important. Here on a larger scale we are using lines of Gliricidia stakes on contour, with the idea being to pollard them back every few months, dropping the cut branches above the lines as a debris fence, which will be continuously buffered with the next wave of cut branches as the gliricidia trunks thicken over time, hopefully holding everything in place and forming terraces of deep soil that also allows for drainage/absorption. Also, along these lines we are planting Bamboo, our future principle crop, which should further help create permanent erosion control lines.
