How Microbes Brought the Worms Back to Old Cane Land

John Caverly ("Ginger John"), Farmer, Onomea, outside Hilo · USA (Hawaiʻi)

Part of the full session video: this talk runs from 0:00 to 5:52. Times below are the video's.

A Hilo-side farmer opens the Microbes (IMO) skill share on the lawn with his own story. His old cane land at Onomea had no earthworms and nothing would grow; after he began making Microbes with Dr. Park, seedlings given Microbes outgrew his organic mix, and 500 lb of IMO-4 laid under a diseased kalo field was followed two weeks later by worms everywhere. He says he has bought no organic fertilizer in seven years and that it takes about 40 days to go from rice to bagged IMO-4.

What they found

The question

Can a farmer's own Microbes (IMO) bring life back to worn-out cane land?

How they tested it

Old sugar-cane land at Onomea, outside Hilo: about 70 years in cane plus commercial sweet potato. He found no earthworms; kalo, bananas and cassava were diseased or would not grow despite bought mulch and organic fertilizer. Seedling test, about eight years before: flats of parsley and of poha, half with his organic mix, half with Microbes added; number of flats not stated here. Field: a large kalo field with mosaic disease, size not stated; on about 1 November, seven years before, during a storm, 500 lb of IMO-4 laid under the kalo and mulched; checked two weeks later. What happened to the kalo disease or yield: not stated. Current practice: Microbes, mulch and animal manures.

What was compared
  • Microbes in the seedling mix — Microbes (IMO) added to half the parsley and poha flats; the other half his organic mix only. Amount not stated.
  • IMO-4 under the kalo — 500 lb of IMO-4 laid under a diseased kalo field and covered with mulch, in the eye of a November storm. Field size, so rate per acre, not stated.
  • Ongoing — Microbes, mulch and animal manures; no bought organic fertilizer for seven years.
Results
  1. Seedlings given Microbes were plainly bigger in two weeks

    "From 100 feet away, you knew which ones had the IMO. They were huge, green, full of roots." Parsley and poha flats, Microbes vs his organic mix. Eyeball judgment; no measurements given.

    ▶ 1:55 As spoken

  2. Worms everywhere two weeks after 500 lb of IMO-4 under the kalo

    Before, he says there was not a worm on the farm ("we didn't have soil, we had dirt"). On Thanksgiving morning he pulled back the mulch and found worms everywhere. Whether the kalo disease cleared is not said.

    ▶ 2:52 As spoken

  3. No bought organic fertilizer for seven years

    He uses Microbes, mulch and animal manures, and says "it works really good". No yield figures.

    ▶ 4:11 As spoken

  4. About 40 days from rice to bagged IMO-4

    Rice out, then IMO 1, 2, 3 and 4: "takes about 40 days, just a little over a month".

    ▶ 5:33 As spoken

Hold it loosely
  • One farmer's story, told from memory; no measurements.
  • The only comparison is the seedling flats, judged by eye; how many flats and how they were scored is not said.
  • The worm count before and after was not measured, and the storm, the mulch and the season changed at the same time as the IMO-4, so the worms cannot be credited to the Microbes alone.
  • The diseased kalo's outcome and yields are not given.
  • Dates are approximate ("about eight years ago", "seven years ago").
For your farm
  • Test it yourself first: split a batch of seedling flats, Microbes in half, your usual mix in the other half, and look in two weeks.
  • Lay IMO-4 on the ground and cover it with mulch.
  • Earthworms are a sign to watch for: in his words, "it's the worms that do the farming".
  • Plan on about 40 days from setting out the rice to having IMO-4 ready.
  • Coming to a class isn't enough; go home and make it.

Next to Master Cho's teaching

  • Agrees

    Lay IMO-4 on the ground and mulch it Cho says scatter IMO-4 so the topsoil is barely covered and do not bury it; in 2017 he adds that it needs mulching out of direct sun. Cho times it 7–14 days before planting; John put it under a standing, diseased kalo crop, which Cho's text doesn't cover. The 500 lb can't be checked against Cho's minimum rate because the field size isn't given.

    Cho, Cho Han-Kyu's Natural Farming (Theory), p. 61

  • Agrees

    Worms come back after Microbes Cho lists 'revitalization of the ecosystem' as a function of IMO: bacteria and fungi first, then nematodes, earthworms and other soil animals.

    Cho, Natural Farming Agricultural Materials (Recipe), p. 8

  • Agrees

    Treat crops and animals with parental love John quotes Master Cho correctly: Cho writes that a farmer should have a parental love towards his crops and livestock.
