Fish Amino Acid (FAA)

Fish Amino Acid is a Korean Natural Farming (KNF) technique adapted widely in India. It converts fish waste — often free from markets and fishing villages — into one of the most potent organic nitrogen sources available.

What It Is

FAA is a fermented fish extract rich in free amino acids, which plants can absorb directly through their leaves and roots — bypassing the need for microbial conversion. This makes it one of the fastest-acting organic nitrogen sources available.

Ingredients

Ingredient	Quantity	Notes
Fresh fish waste (heads, guts, scales, tails)	1 kg	Any fish waste works
Crude brown sugar / jaggery	1 kg	Exactly 1:1 ratio by weight

That's it. Two ingredients.

The Science

When sugar (high osmotic pressure) is mixed with fish waste, it draws water out of the fish tissue via osmosis, creating a brine. Naturally occurring bacteria ferment fish proteins into free amino acids — the same amino acids found in commercial fertilizers, but at near-zero cost.

Amino acids present: 18 types including glutamic acid, alanine, glycine, lysine, arginine. These are directly absorbed through stomata (leaf pores) and root hair cells without any soil conversion needed.

Preparation

1. Chop fish waste into small pieces (1–2 cm)
2. Mix 1:1 by weight with jaggery or brown sugar
3. Place in container — do NOT seal airtight (cloth cover is fine)
4. Press contents down and keep weighted with a stone or heavy lid
5. Ferment at room temperature for 3–6 months
6. Liquid accumulates at the bottom — drain off the FAA
7. Filter through cloth, store in bottles

Signs of good FAA:

• ✓ Dark brown to reddish liquid
• ✓ Strong fermented fish smell (normal — it's very pungent)
• ✓ Slightly syrupy consistency

The smell is intense. Store away from living areas.

NPK and Nutrient Content

Nutrient	Content
Nitrogen (N)	4–8%
Phosphorus (P)	1–2%
Potassium (K)	1–2%
Calcium (Ca)	Significant
Trace minerals	Iron, Zinc, Magnesium + more

This is a high-nitrogen fertilizer — treat it accordingly. Always dilute before use.

Application Rates

⚠️ VERY DILUTE — FAA is concentrated. Over-application burns plants.

Method	Dilution	Notes
Foliar spray	1–2 mL per 1 L water	Start at 1 mL/L, test on small area
Soil drench	2–5 mL per 1 L water	Mix with Jeevamrutham for synergy
Drip fertigation	2–3 mL per 1 L water	Filter to 50 microns first

Best timing:

• Foliar: Early morning or evening (stomata open; UV won't destroy amino acids)
• Soil: Any time, but morning preferred for best microbial interaction

Frequency: Every 15–21 days, or at nitrogen-demanding growth stages (vegetative flush, after transplanting)

Benefits

• Instant N delivery — amino acids absorbed within hours of foliar spray
• Root growth stimulator — glutamic acid and other amino acids directly stimulate root elongation
• Cellular strength — amino acids build plant cell walls and proteins
• Yield quality — documented improvements in protein content of grains and sugar content of fruits
• Complements Jeevamrutham — excellent tank mix

Where to Get Fish Waste in India

• Local fish markets (talaab/machli mandi) — often free or ₹5–10/kg for waste
• Fishing villages along coasts
• Inland fish processing units (carp, catfish, tilapia)
• Aquaculture farms (often discard skins and offal)

Cost Analysis

Item	Cost
Fish waste (1 kg)	Free – ₹10
Jaggery (1 kg)	₹40–50
Total for ~500mL FAA (after 3–6 months)	₹40–60

At 1 mL/L foliar dilution, 500 mL FAA makes 500 L of spray solution — covers multiple acres.

Caution

• Strong smell — inform neighbors if in urban/peri-urban setting
• Test on small area first — some crop varieties are sensitive to fish proteins at higher concentrations
• Do not mix with lime-containing products — precipitation occurs
• Shelf life of finished FAA: 1–2 years in sealed container
