Indigenous Microorganisms Stage 2 — KNF Recipe

The second stage of IMO preparation where collected forest microorganisms (IMO1) are mixed with rice bran and brown sugar to multiply the microbial community. IMO2 is a dense, inoculant-rich substrate used to prepare IMO3 and ultimately soil amendments.

The second stage of IMO preparation where collected forest microorganisms (IMO1) are mixed with rice bran and brown sugar to multiply the microbial community. IMO2 is a dense, inoculant-rich substrate used to prepare IMO3 and ultimately soil amendments. This KNF preparation is made with imo1 (rice collected from forest, colonized with white mycelium) – 1 part by weight and is a staple input in regenerative Korean Natural Farming — feeding soil biology instead of relying on synthetic fertilizers. It is one of 50+ free recipes we use daily at the IC SPICY nursery in Port Charlotte, Florida.

Ingredients

• IMO1 (rice collected from forest, colonized with white mycelium) – 1 part by weight
• Rice bran (or wheat bran) – 1 part by weight
• Brown sugar – equal weight to IMO1
• Water – enough to achieve 60–65% moisture (squeeze test: a few drops from a clenched fist)

Steps

1. Prepare IMO1 first: place cooked rice in a wooden box in a forest for 5–7 days until covered with white mycelium.
2. Mix IMO1 with equal parts rice bran and brown sugar.
3. Add water gradually until the mixture reaches 60–65% moisture (it should hold shape when squeezed but not drip).
4. Pack loosely into a wooden box or crate. Cover with breathable cloth.
5. Allow to ferment at ambient temperature for 3–5 days, checking daily for heat and moisture.
6. The mixture should smell sweet and earthy. Avoid strong ammonia odors (too wet or too warm).
7. Once fermentation stabilizes (temperature drops), IMO2 is ready to use or store.

Common questions

How long does Indigenous Microorganisms Stage 2 take to make?

Timing depends on temperature and humidity — follow the step-by-step schedule in the recipe above. Fermented and cultured inputs improve with proper timing, so avoid rushing stages.

When should I apply a KNF input like this?

Match the input to the plant's growth stage, per Master Cho's nutritive cycle theory: vegetative-stage plants favor growth inputs like FPJ and FAA, while flowering and fruiting plants favor WCA and FFJ. Apply early morning or late evening, and never in strong midday sun.

Is this safe for organic or no-spray gardens?

Yes — like all IC SPICY CookBook recipes, this uses only biological and food-grade ingredients with zero synthetic fertilizers or pesticides. Always label your jars, use clean tools, and do a small test application before treating every plant.
