Livestock Feed Ratios, Water-Soluble Calcium, Ensiling with IMO4

Drake opens by fermenting the fall harvest for spring use and winterizing garden beds with IMO and leaf mulch. He walks through vinegar care: strain the solids, lightly heat the finished vinegar below pH 2.4 to stop scobies from regrowing, and start a scoby hotel from the leftovers.

On water-soluble calcium, he explains why calcium hydroxide (slaked lime) won't work — it has no carbon for the vinegar to react with — while calcium carbonate (eggshells, limestone, shellfish) releases CO2 and makes true KNF reproduction. He also covers Master Cho's livestock feed formula: about one-third leaves and roughage, 30% roots/grains/proteins, 30% fruit, and 10% activated IMO, mixed with maintenance solution diluted 1:1000 and a cup of seawater to reach 80% moisture. He demos Ray Yoon's ensiling method — 15cm layers of shredded material dusted with activated IMO (IMO4), sealed airtight for at least four weeks.

Q&A covers whether spent mushroom blocks work for IMO collection (no, use fresh carbs instead), why floating fish in an old can of fuel is fine after six months of fermentation, and why Jadam fish liquid is nastier and less reliable than KNF fish amino acid. He also walks through Master Cho's soil-recovery slides on no-till pyramid planting and why heavy chemical fertilizer use weakens roots and locks farmers into buying more.

He closes with his January 2023 KNF class dates on the Big Island and points listeners to knfsupport.com, a searchable archive of past office hours episodes, after pureknf.org went down.

Questions answered

  • 4:34 What should I be preparing now for spring? — Ferment whatever you're harvesting now all winter, then save sugar for the new shoots coming up in spring.
  • 5:21 What should you do to winterize the garden right now? — Rake up leaves into your beds, dust with IMO or cheap microbes, and let it break down all winter.
  • 7:33 Do you need to take out the solids when your vinegar is done? — Strain them off, then lightly raise the temperature so scobies stop growing back.
  • 11:31 Can I make water-soluble calcium (KNF reproduction) from calcium hydroxide? — No — calcium hydroxide has no carbon to react with vinegar; use calcium carbonate like eggshells or limestone instead.
  • 16:36 How much maintenance solution goes into chicken feed, and how do you store it? — He freehand-pours about two ounces into a two-thirds-full five-gallon bucket and stores the mix with a breathable lid.
  • 20:41 What is Master Cho's livestock feed formula? — About one-third leaves and roughage, 30% roots/grains/proteins, 30% fruit, and 10% activated IMO, brought to 80% moisture with maintenance solution and seawater.
  • 22:56 How does Ray Yoon ensile feed material? — Layer 15 centimeters of shredded material with a dusting of activated IMO and KNF protectors, repeat, then seal airtight for at least four weeks.
  • 26:17 If I remove the brick and my fish floats after six months in the can of fuel, is that a problem? — No — once fish has fully fermented for months, floating without the brick is not an issue.
  • 27:50 Can spent mushroom blocks supplement IMO collection? — No — the mushrooms already ate the carbohydrates; use a fresh carbohydrate source for collection instead.
  • 28:36 How does Jadam-style fish liquid compare to KNF fish amino acid? — Jadam is nastier and breeds more pathogens; KNF fish amino acid does the same job without the stink.
  • 46:25 Do FPJ and LAB help start a worm bin? — Sometimes — soaking the bedding lightly in them helps kick off the fermentation breakdown.
  • 48:00 What happens to soil when you apply chemical fertilizer? — It kills IMO, hardens back into rock form within about two weeks, and shuts down the roots' own ability to fix nitrogen.
  • 53:04 Any other KNF books worth reading? — The Jadam book is decent; Rohini Reddy's book and the Filipino book are not good.
  • 1:00:03 pureknf.org is down — where can I find past episodes? — Use knfsupport.com, which has a searchable table of contents for every office hours episode.
