Down to Earth™ Liquid Fish & Kelp 2-4-1 All-Purpose Fertilizer — 1gal / OMRI Listed®

Liquid Fish & Kelp 2-4-1 — Fish Protein and Seaweed Biostimulant in One Bottle

Down To Earth Liquid Fish & Kelp 2-4-1 combines the nutritional power of hydrolyzed fish protein with the plant growth-promoting benefits of cold-water Ascophyllum nodosum seaweed extract into a single all-purpose liquid fertilizer. The 2-4-1 NPK profile emphasizes phosphorus for root establishment, blossom development, and fruit set, while nitrogen supports vegetative development and potassium enhances stress tolerance.

Hydrolyzed fish protein provides directly available amino acids, peptides, and organic nitrogen that stimulate soil microbial activity, and the Ascophyllum nodosum seaweed extract contributes naturally occurring plant hormones, trace minerals, and biostimulant compounds shown to improve germination rates, root development, transplant establishment, and plant stress tolerance. This 1-gallon size is OMRI Listed for certified organic production and suitable for vegetables, herbs, fruits, vines, and ornamentals.

Frequently Asked Questions

Can Liquid Fish & Kelp be used as a foliar spray?

Yes. Diluted Liquid Fish & Kelp can be applied as a foliar spray for rapid nutrient and biostimulant delivery directly to leaf tissue. Apply in early morning or evening to minimize evaporation and potential leaf burn.

Does the fish component smell when diluted for use?

A mild fish odor is present but dissipates quickly after application and soil absorption, and the seaweed component adds an earthy marine note. Odor is not an indicator of product quality.

How is this used in drip irrigation systems?

Yes. Filter the solution appropriately (100-200 mesh inline filter) before running it through drip lines to prevent emitter clogging from undissolved organic particles, and flush lines after each application event.

What makes Ascophyllum nodosum seaweed different from other seaweed sources?

Ascophyllum nodosum is harvested from cold North Atlantic waters and is among the most researched seaweed species for agricultural use. It naturally carries high concentrations of alginates, mannitol, and growth-regulating compounds that support its biostimulant reputation.
