Nematodes, NPK Cycling, IMO Microscopy, Soldier Fly Larvae

Joel (PostUp Media) sends microscope photos of a one-fifth dilution from a fresh IMO4 pile: over 40 nematodes, 20-30 fungal hyphae, testate amoebas, and plenty of LAB. Drake walks through the images, segmented fungal hyphae, bacterial-feeding nematodes, flagellates, and explains why nematodes matter. They eat nitrogen-loaded bacteria, digest only a fraction of the NPK, and poop out the rest as soluble nutrient right in the root zone, which is why natural farming outperforms broadcast chemical fertilizer.

Stonemason's IMO4 is balling up clay soil into nutrient-rich nuggets, the same principle behind EM bokashi balls thrown into rivers and lakes. Black soldier fly larvae showing up in the Disgustingly Cheap Food (JLF) barrel are fine and just speed up breakdown, but larvae in a fermented plant juice (FPJ) extract are a problem since they eat nutrients meant for you. Pull them out and reseal with a solid lid after supersaturating with sugar.

Pig housing questions cover Drake's own Conway-greenhouse barn with a split roof, Spencer Karren's welded pig pens, and Mr. Lee's farm in Korea where chickens and pigs share the same pens, with pigs eating chickens as the main risk. JADAM is Korean natural farming too, not separate. A fruit ferment made with LAB and sorghum molasses is really a fermented plant extract (FPE), cheaper and less concentrated than FPJ but still effective. JMS / Disgustingly Cheap Food can't be kept past 3 to 5 days before anaerobic putrefaction microbes take over.

Quick answers: the KNF Recipe Book PDF is free at knfsupport.com; biochar soaked too long in anaerobic tea just needs drying out or a day in a 1:500 LAB solution; IMO stages run roughly 5 days for seed IMO1, 3 days to preserve it, then 7 to 11 days each for IMO3 and IMO4, about a month total; and fall is fine for starting IMO collection as long as it goes out before winter.

Questions answered

  • 35:18 Is black soldier fly larva a bad sign in the Disgustingly Cheap Food (JLF)? — No, they break the material down and simplify it; keep loading grass and drown them if you want.
  • 36:50 What about soldier fly larva living in a fermented plant juice (FPJ) can of food? — That's a bummer since they eat nutrients meant for your extract; pull them out, add more sugar to supersaturate, and seal it with a solid lid.
  • 38:28 How do I find and collect IMOs in the desert (Mike, Texas)? — Check microbialsecret.org's Desert KNF episode and the irrigation-without-water episode, or search 'desert' in the office hours archive on knfsupport.com.
  • 41:12 Should I raise pigs in a greenhouse or build a traditional KNF livestock structure? — Drake's own barn is a Conway greenhouse with a split roof that vents air off the top; also check Spencer Karren's welded pig pens on Facebook.
  • 44:47 Is my KNF/JADAM hybrid fruit ferment with LAB and sorghum molasses good, and is JADAM separate from KNF? — JADAM is Korean natural farming too; what you're making is a fermented plant extract (FPE), cheaper and less potent than FPJ but it works.
  • 47:40 Can you prolong the viability of JMS (Disgustingly Cheap Food) beyond five days? — No, after 3 to 5 days anaerobic zombie putrefaction microbes take over from the worker microbes, so just make a fresh batch.
  • 49:25 Have you heard of maize producing a gel on brace roots to attract nitrogen-fixing bacteria? — Yes, that's a root exudate; most plants secrete sugars and gels around roots and leaves to draw in beneficial microbes.
  • 51:27 Can I house 20 chickens and 3-4 pigs under one 12x12 roof with a 6-foot hallway? — It can work as long as the pigs don't get a chance to eat the chickens, and the chickens will happily eat the pig manure.
  • 54:09 Where can I get the PDF of the KNF Recipe Book? — Download it free at knfsupport.com, which links to the book from Natural Farming Hawaii.
  • 55:00 Biochar has soaked two weeks in an anaerobic compost tea, can LAB fix it? — Dry it out and oxygen will kill the bad microbes, or soak it a day in a 1:500 LAB solution; if it doesn't smell rotten, it's fine.
  • 56:19 How long does it take to get each IMO stage? — In the tropics it's about 5 days for seed IMO1, 3 days to preserve it, then 7 to 11 days each for IMO3 and IMO4, roughly a month total to reach IMO4.
  • 58:35 Can chickens and pigs run in the same pens, like at Mr. Lee's farm? — Yes, Drake saw it done in roughly 12x24-foot pens at Mr. Lee's farm; a full livestock talk is coming later.
  • 1:01:26 Is it okay to start IMO collection in fall instead of spring? — Yes, fall works too; just leave collections out a bit longer and get the finished IMO out before winter so it grows in with the snowmelt.
