Fish Fertilizers: Emulsion vs. Hydrolysate—Know the Difference

Not all fish fertilizers are equal. Fish emulsion: menhaden cooked, pressed for oil (cosmetics/paint), remainder → animal feed, leftovers → emulsion. Nutrient-depleted byproduct. Liquid hydrolysate: cold-pressed whole fish preserves vitamins, minerals, proteins, oils. Far richer, often outperforms synthetics. Both smell fishy—pets may investigate.

Choose Concentrated Nutrition

Hydrolysate delivers complete fish nutrition to your soil biology. Emulsion is a shadow of the source. For serious organic feeding, the processing method matters. Keep pets away from fresh applications.
