Erosion control: an experiment using sheep wool
July 26th, 2008 at 04:47 pm by Shari Thomas in Around the Farm, SheepOk, so I’ve got about 25 trash bags of fleece that is unacceptable to most hand spinners. It’s not enough to send to the “co-op” as you really need at least 100 times that amount.
The chickens are all comfy in their wool-lined nests and won’t need new wool for many months.
Experiment time!
I’ve heard about wool being used for erosion control when you need to soak up (or divert) moisture as there is a company in Oregon who is making such a product. They’re also making dog beds with 75% wool and 25% cedar chips (odor control).
Here on the desert, we rarely need “moisture control” aside from when the snow melts too fast, or we get a rare summer deluge. What we need more often is a way to keep our sand from going to the neighbor’s, and another neighbor’s sand from coming to visit our acreage.
Believe me, it’s not a pretty sight. You can’t breathe when sand is blowing all around, including into your house!
My thesis: Lay down raw wool on high erosion areas after clearing the area of any small vegetation. Weigh it down temporarily until adjacent blowing sand can impregnate the air around the fibers. In theory, the trapped sand will be unable to escape. That includes any sand trapped by the fibers as well as the sand underneath the wool.
I’ve read a number of studies out of eastern Canada and the United Kingdom regarding the use of “wool waste” for soil amendments, so perhaps we can get an additional benefit. With virtually no way to irrigate our acreage, whatever is eventually planted will need a relatively rich soil, with awesome moisture storage ability.
What I don’t really know is how long it will take for the wool to break down. I do know it’s pretty slow to decompose, however, I’m counting on UV degradation, as our sheep always have “sun-bleached tips”. I’m also thinking the abrasion from the sand will have some effect. If it takes a couple of years, and holds our sand in place, then that’s a good deal.
Buy me a beer and I'll write more posts more often.
