Hydrophobic Soil, KOH Soap, Chick Feeding Schedule

Drake opens with the I Ching reading on Feng, abundance, then covers storm damage from the night before: the drone shelter collapsed but the generator's cast iron took the hit, sparing the drone itself. He and guest Mark also patch the back deck with tar against Hawaiʻi's weather.

On the chicken coop, keeping the floor around 15% moisture with light misting instead of heavy watering has cut dust and smell, and the same idea comes up for hydrophobic soil: no known plant surfactant works well, so regular misting beats blasting the ground. Mark shares a KNF soap recipe of canola oil, water, and potassium hydroxide (KOH) as a cheap surfactant that also works for hair, laundry, and dishes.

A banana vinegar batch came out weak because the class didn't add enough sugar for osmotic extraction. The boxed IMO pile, raised off the soil, stopped reheating after turning, and Drake floats grounding it with a rod or wire to keep an electrical connection to the earth. Christoph in Belgium is testing KNF soil blocks, including sterilized IMO as a dead control, plus a heat mat to warm blocks in cold weather.

Mark talks about his specialties, plumbing, alcohol fuel, and community resilience from the Hawaiian Acres Sustainability Hui. Drake describes pitching the foundation's drone as a way for Hawaiʻi County to spray IMO on little fire ants and coconut rhinoceros beetle instead of poison, and building a research partnership with NRCS and CTAHR that needs controlled data to officially recommend KNF solutions. A member Q&A tool pulls Master Cho video clips directly, answering a question on feeding baby chicks boiled egg.

Questions answered

  • 6:06 How do you keep a chicken coop from smelling and staying dusty? — Keep the floor about 15% moisture and mist lightly instead of soaking; that cuts dust, odor, and flies.
  • 12:29 What's the pitch to Hawaiʻi County for using the drone on ag pests? — Spray IMO by drone for the County instead of poison sprays on little fire ants and coconut rhinoceros beetle.
  • 22:31 What natural plants work as a surfactant for hydrophobic soil in Hawaiʻi? — Neither Drake nor Mark knows a good plant surfactant; better to mist the soil regularly than chase a chemical fix.
  • 23:58 Why does hard watering make hydrophobic soil worse? — A hard blast just explodes on the surface and erodes dry dirt into dust; a fine mist actually wets it.
  • 26:04 How do you make a cheap KNF soap or surfactant? — Canola oil, water, and potassium hydroxide (KOH) makes a basic soap that also breaks soil surface tension.
  • 28:09 Why did the banana vinegar batch come out low-volume? — Not enough sugar was added for the amount of fruit, so osmotic extraction pulled less juice than expected.
  • 31:49 Why didn't the boxed IMO pile reheat after turning? — Raising it off the ground in a box may have cut its electrical ground connection; testing a grounding rod next.
  • 38:29 When do you feed brown rice, boiled egg, and bamboo leaves to baby chicks? — A member-clip search found Master Cho feeding boiled egg from day 3 through 3 weeks, about 1.5 eggs total.
  • 51:55 What data do NRCS and CTAHR need to officially recommend KNF solutions? — Controlled studies comparing treated versus untreated plots, documented well enough to back a formal recommendation.
  • 52:40 How do you test whether it's the IMO microbes or just the material helping soil blocks? — Autoclave or sterilize one batch of IMO as a dead control and compare it against live IMO in the same blocks.
  • 58:27 Do seedling heat mats help soil blocks in a cold climate? — Yes, a plug-in heat mat can bring blocks up to about 20-25°C to speed germination.
