Brown’s Fish Fertilizer 2-3-1
Cold-Processed Fish Hydrolysate for Soil Biology, Growth & Bloom Support
Brown’s Fish Fertilizer 2-3-1 is a whole fish hydrolysate made using a cold enzymatic process that preserves the full biological value of the fish, including oils, amino acids, vitamins, and micronutrients. Unlike fish emulsions, hydrolysate retains natural compounds that feed both plants and beneficial soil microbes.
This slow-feeding liquid is ideal for vegetables, fruit trees, herbs, flowers, and compost teas, offering a balanced nutrient profile and microbial stimulation for root growth, vegetative strength, and flower production.
Key Characteristics
-
Balanced Nutrients + Microbial Food
With a gentle NPK of 2-3-1, this fish hydrolysate provides readily available nitrogen for leaf growth, phosphorus for strong roots and blooms, and potassium for stress resistance—plus natural amino acids and fish oils that feed soil biology. -
How to Use in Soil, Foliar Spray, and Compost Tea
-
Soil drench: Mix 2–4 tbsp per gallon of water; apply at root zone every 1–2 weeks.
-
Foliar feeding: Dilute 1–2 tbsp per gallon and spray in early morning or evening.
-
Compost tea: Add 1–2 tbsp per gallon as a microbial food during brewing.

Cold-Processed to Preserve Nutrients and Oils
