Comparison: Best Fish Emulsion On Lawn (Updated | Dec 1st)

Look at the NPK ratio to match your lawn’s nutrient needs, the concentration (how much water you need to mix per gallon), and any certifications like OMRI organic status. Also check for added micronutrients such as iron, manganese, and zinc, which can improve grass health. Finally, consider odor control features, especially if you have nearby neighbors.

Both products share a 5‑1‑1 NPK ratio, but Liquinox highlights additional trace minerals like iron, manganese, and zinc, which can benefit soil fertility. Alaska’s formula is deodorized with natural wintergreen, making it less odorous, while Liquinox emphasizes a non‑burning formula safe for vegetables and lawns. Application rates are similar, though Liquinox recommends using it for both soil and foliar feeding.

OMRI certification guarantees the product meets organic standards, which is important for certified organic gardens and for consumers avoiding synthetic inputs. Safergro also provides a high level of amino acids, vitamins, and minerals that support both plant growth and beneficial soil microbes. Non‑certified products may still be effective, but they lack the official organic verification.

Products sold in gallon or larger containers, such as Alaska Fish Emulsion (1 gallon) and Liquinox 7128 (1 gallon), typically provide a lower cost per ounce compared to 8‑oz or 32‑oz bottles. The higher concentration formulas can be diluted to cover more area, stretching the product further. Consider also the recommended mixing ratios; a concentrate that makes 6‑10 gallons per quart can be more economical.

Liquinox 7128 and the Fish Hydrolysate (2‑3‑2) specifically mention suitability for both soil drench and foliar applications, allowing flexible use. The 5‑1‑1 products like Alaska and Fertilome can also be applied as a foliar feed, but they emphasize soil feeding for best results. Always follow the label’s dilution instructions to avoid leaf burn when spraying.

Odor can be a significant factor for indoor or close‑quarter gardening; products like Alaska Fish Emulsion are deodorized with natural wintergreen to reduce smell. Other brands may have a stronger fishy scent, which some gardeners find acceptable outdoors but may be undesirable near living spaces. If odor is a concern, prioritize deodorized or low‑odor formulations.

Amino acids act as building blocks for plant proteins, supporting faster growth and stress resistance, while vitamins can enhance enzymatic activity in the soil. Safergro’s blend of 20 amino acids, 13 vitamins, and 8 minerals promotes both plant health and beneficial microbial activity. This comprehensive profile can be especially beneficial for nutrient‑poor soils.

Yes, most of the listed products, including Alaska, Liquinox, and Harris Organic Fish Fertilizer, are labeled safe for use on lawns, vegetables, and a wide range of ornamental plants. Ensure you follow the specific mixing ratios for each plant type—lawn applications often require a lighter dilution than vegetable beds. Checking the label for any crop‑specific restrictions will help you avoid over‑fertilizing.
