There's a new hill that was built at a friends place, and since I'm into permaculture he asked me what type of mycelium I would recommend covering the hillside with before winter comes. He has also recently seeded it, so it's likely going to be a rough winter on the new hill. I've heard about water cannon sprinkling of mycelium, so I'm thinking along those lines for what I should tell him.
Paul Stamets talks about erosion control of old logging tracks using substrate inoculated with oyster mushroom spawn.
Our intention is to prevent further bank erosion as well as filter the flow of silt-enriched water. We arranged for the delivery of 'hog-fuel', a crude mixture of bark, wood chips, and fir needles, in 10-yard loads. North Mason Fiber donated the hog fuel while Fungi Perfecti paid for the trucking. Seven employees donated their time to spread material. The crew ('Team MycoForce') spread the wood chip matrix to a depth of 3 to 12 inches. After the hog-fuel was spread, we applied spawn of a native mushroom species, the Oyster Mushroom, Pleurotus ostreatus, on the top surface of the hog-fuel. Six bales of wheat straw were spread out over the top.
The straw acts as a protective layer, holding in moisture and preventing the spawn from drying out. We seeded the sites using a broadcaster filled with MycoGrow®, a mycorrhizal inoculum, and Regreen®, a non-seeding wheat approved for erosion control. Twenty pounds of seed and one pound of mycelial inoculum were broadcast over the straw. This site was inoculated over two days on the 11th and 12th of April, at the time of intermittent, heavy rainfall.
