It’s not an overnight miracle product, but it seems to support long-term soil health and helps the lawn respond better to regular watering and care. A little goes a long way since it’s concentrated, so the value is there. Just make sure to follow the dilution instructions carefully. Overall, a reliable product if you’re looking to improve your lawn’s soil condition and give your grass a steady boost. Review: Great for my indoor garden. Helps plant to use the nutrients in the soil. - I grow most of our veggies and herbs year around under LED lighting. I had been adding compost to my potting soil, but found that compost lowers the PH of the soil as it decomposes for use by the plants. This humic acid is organic, has the same benefits as compost, but does not change the PH of the soil as it does not have to be broken down for use by plants. Humic acid is not a fertilizer per se. It is an effective soil conditioner that should be used with fertilizer to help the plants utilize the nutrient in the soil. The only warning on the bottle is that this product should not be used with fertilizers high in calcium (calcium nitrate) or have a low PH. Before buying this product, I did some research and found this information. The benefits of using liquid humic acid are: 1) It improves the availability of micronutrients in the soil, allowing roots to absorb the more efficiently. 2) It enhances soil texture by promoting better aeration and water retention. 3) It feeds microbes that help plants grow naturally. 4) It works for both indoor and outdoor plants. 5) It can significantly impact plant health, resilience, and productivity. 6) It does not change the PH of the soil. To summarize, liquid humic acid improves the soil, feeds beneficial microbes in the soil, and helps plants to utilize nutrients in the soil. Since the recommended usage of the product is 1/4 to 1/2 cup per gallon of water, the gallon size is much more economical depending on your watering needs. Although I use this humic acid on some of my younger plants, I have found it to be most beneficial on my older plants since many of them are 2-5 years old. I have been adding this product to my watering water once or twice a month and my plants are all doing great. Veggie greens are growing faster, and fruiting veggies such as tomatoes and peppers are getting more and larger fruit. If you are serious about the plants you grow, I recommend trying this humic acid to see an increase in productivity. I hope this review was helpful for you. ## Features - IMPROVES SOIL STRUCTURE & NUTRIENT AVAILABILITY- GS Plant Foods Humic Acid Soil Amendment supports healthy soil by enhancing cation exchange capacity and helping the root zone access existing nutrients in the soil more efficiently.

Why is it not listed on the bottle? Other sellers do this? How know this is legit?** A: 12% Humic Acid is available on Amazon. Just search for it. According to the manufacture, this stuff contains 8%; but they aren’t willing to label their product as such, so do you trust them? Personally, I’ll buy the 12%. Although it costs more per gallon, you’re actually getting more per dollar. **Q: What percent humic does this have?** A: It's weaker than humic acid sold by other brands. Can tell as soon as you open the bottle. **Q: Why is guaranteed analysis of this product not listed anywhere? this should not be an amazon choice product until it can be proven.** A: I don’t know why there is no guarantee analysis but I have been using this to bring my ponytail palms back from having root rot and it is working fantastic **Q: What is the active and inactive ingredients?** A: What you want to know is how much carbon is in this product compared to oxygen. Common humic acid has about 60% carbon and 40% oxygen, but that varies depending on the source. You also want to know how much humic acid is in this product. The answer is 8%. (NOT 80%) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Noticeable lawn health boost, easy to use *by B***S on May 4, 2026* I used this humic acid concentrate on my lawn to help improve soil quality, and it has been a solid addition to my lawn care routine.
