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

Down to Earth™ Liquid Fish & Kelp 2-4-1 All-Purpose Fertilizer — 1 Gallon

Down to Earth™ Liquid Fish & Kelp 2-4-1 combines the nutritional power of pure 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 and overall plant vigor — making it effective across the full production cycle from seedling establishment through harvest.

Hydrolyzed fish protein provides directly available amino acids, peptides, and organic nitrogen that stimulate soil microbial activity and feed plants directly — accelerating the biological activity in the root zone that drives nutrient cycling and structural soil improvement. The Ascophyllum nodosum seaweed extract contributes a complex of naturally occurring plant hormones (including cytokinin-like and auxin-like compounds), trace minerals, and biostimulant compounds that have been shown to improve germination rates, root development, transplant establishment, and plant stress tolerance. OMRI Listed® for certified organic production. Suitable for use on garden vegetables, herbs, fruits, vines, and ornamentals.

Key Features & Benefits

• Hydrolyzed Fish Protein + Ascophyllum Seaweed — Synergistic combination of fish-derived amino acids and seaweed biostimulants delivers multi-mode plant benefits beyond standard N-P-K nutrition.
• Stimulates Soil Biology — Organic nitrogen and amino acid inputs from fish protein feed beneficial bacteria and fungi, building long-term soil food web health and nutrient cycling capacity.
• Supports All Growth Stages — Balanced macronutrient profile and biostimulant content provide value from seedling establishment through reproductive development and harvest.
• Promotes Longer Growing Periods — Seaweed cytokinin-like compounds delay leaf senescence and support extended production windows in seasonal crops.
• OMRI Listed® — Approved for certified organic vegetable, herb, fruit, and ornamental production programs.

Who Should Use This

Organic vegetable and herb producers, fruit and vine growers, and ornamental nurseries looking for a versatile liquid fertilizer that combines macronutrient nutrition with biological soil stimulation and seaweed biostimulant benefits will find Liquid Fish & Kelp 2-4-1 an effective single-product solution for routine fertigation and foliar feeding programs. It is particularly valuable for growers who want to incorporate fish and seaweed nutrition without managing two separate liquid products.

Compatibility

Dilute before application. Compatible with most OMRI-listed organic fertilizers and amendments. Perform a jar test before tank mixing. OMRI Listed® for certified organic production. Available in 1 gallon.

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. The seaweed component adds an earthy marine note. Odor is not an indicator of product quality.

Can this be used in drip irrigation?

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

What makes Ascophyllum nodosum seaweed better than other seaweed sources?

Ascophyllum nodosum is harvested from cold North Atlantic waters and is among the most researched seaweed species for agricultural use. Its naturally high concentrations of alginates, mannitol, and growth-regulating compounds make it a premium standard in the seaweed biostimulant category.
