Sponge and A-Frame Workshop, Saturday, March 22, 2014
by Christian Meuli
The sponge is a useful rainwater harvesting technique that needs little maintenance. A sponge is a hole dug into the ground and filled with moisture-holding household waste. I find sponges to be invaluable in establishing tree saplings on windy, dry sites with poor soil and in reinvigorating old trees.
Sponges made of carbon materials passively hold winter snows and summer rains for months afterward, storing moisture efficiently in the soil and recycling carbon back into our depleted desert soil. Sponges retain moisture safely out of the harsh sun and drying wind right next to growing roots. Sponges are a simple and convenient way to very-locally recycle newspapers, cardboard, magazines, phone books, junk mail, confidential papers, yard cuttings, clothes, etc.
First we will visit a variety of mature sponges and their effects on nearby plants. Next we will dig and install several sponges with the carbon material that each attendee will bring with them. We’ll use an A-frame to identify the contour and to design how to harvest the rainwater most efficiently, dig and fill the sponge, and mulch it to look as natural as possible.
Then we’ll form groups of three to make state of the art A-frames that are durable, light-weight and foldable. I aspire for these groups to share an A-frame together, using them in varied conditions over the seasons and sharing outcomes with each other. I’ll give everyone marking flags so you can immediately begin implementing sponges on your own site!
Schedule:
Saturday, March 22, 2014
9AM – 1PM at La Resolana, Edgewood
9 AM Site tour of successful sponges and a sponge ladder
10 AM Make several sponges: identify contour, dig hole and berm the
downhill side, fill with carbon waste, step down the materials,
mulch, armor the downhill berm, water(?), extend arms of berms,
and take pictures
11 AM- 1 PM Make A-frames (the rainbarn has a woodstove)(I have tools and materials
Cost:
$25 with scholarships available. Limited to 18 people. Please e-mail me your contact information including a current e-mail and phone number. Participants will bring a large bag of sponge material, gloves, and a shovel.
I cancelled the sponge workshop last fall due to a 14” snow. I hope each of you that had signed up previously will be able to attend this next workshop. I plan on having a woodchip berm and A-frame workshop before the summer rains begin.
I look forward to sharing this simple rainwater harvesting technique that is extremely beneficial,
