The Andersons HumiChar Organic Soil Amendment with Humic Acid and Biochar Covers 12,000 sq ft (12 lb)

I've used this for some time now and witnessed poor soil turn good. Good soil means healthy growing. It also means less chemicals contaminating my plants and soil hardening. Less water, fertilizer, labor and weeds to worry about (I sure do hate weeds). Wish I knew about this sooner.

Humichar! Works really good at keeping in moisture

If you live in the South and deal with sandy soil, I want to share something that truly changed my lawn: biochar. It’s not just hype—it works.When we bought our home, our soil was bleeding out nutrients and water faster than I could put them in. I ran soil tests and realized I was throwing money away on fertilizers that couldn’t stick. That’s when I started digging into real solutions—and that’s how I found biochar.Now, I apply it twice a year with the goal of reaching 200 pounds over the next few seasons on our front lawn. It’s an investment—$600 to $800 total—but here’s the thing: biochar lasts 100 years or more in the soil. It locks in nutrients, holds water, and transforms how your soil works.By the time my plan is complete, we’ll likely cut our irrigation needs by 40% and reduce fertilizer use by half—so it ends up paying for itself if you’re willing to be patient and consistent.Here’s what I’ve learned:• Charge the biochar with organic fertilizers—they feed the microbes and bring the biochar to life.• Add micronutrients and macronutrients when applying—it’s like seasoning the soil properly.• Stick with it. Every application improves CEC (cation exchange capacity) and builds the kind of soil plants thrive in.If you’re not sure how much to use, you can use tools like GPT (yes, the AI!) to calculate the right amount based on your lawn’s square footage and your soil goals. If your soil is sandy and struggling, this is one of the most powerful long-term changes you can make.Take your time. Stay consistent. You’ll be amazed at what your lawn can become with healthy soil.**04/15/2025 Update: Added photo of soil profile from a sod plug I pulled from my lawn. Look at the top profile with only 100 pounds added past 18 months! Good bye sand!**8/13/2025 Update: Centipede Grass and full lawn healed now that sandy soil is gone after 20 Months do yourself a favor and invest in biochar/humichar

I have applied this to my lawn (northern climate lawn) each spring for multiple years while also following a Scott’s seeding and fertilizer program. In combination with a high quality seed, I’ve noticed this always boosts our lawn health for very green grass.Our home was a new build in 2020 and the soil was nutrient deficient (I tested it). Lots of clay from the excavated earth that was dumped around the property when they dug the foundation. Applying this product has helped progressively improve our soil pH over the past 4 years!

This is a great product to add carbon and humic acid to the soil, but it is pricey, and for that I am taking away 1 star. If you have red clay soil, especially with a new lawn, humic acid can really bring it to life with less nitrogen while really improving water retention. I have since found a more cost-effective way to apply humic acid, but if you're new to lawncare or have a small yard, this will be a 5+ star product.

This is the second application (of Andersons Humic Acid ) that I’ve used on my lawn. What a difference this product made. I had some major bald spots in my grass and lawn look terrible. Two months after the first application all the bald spots were gone and my grass looked really good. I applied the second application three months after the initial application and my lawn looks even better. It’s a bit expensive and it does take some time to work, but it’s worth every penny

This product in money in GA clay. Takes a lot of applications but my solid is turning black! Yard is becoming healthier every year. I live on .5 acres and I have put down maybe 7 treatments and Im already seeing results. The good news is once the soil improves you can discontinue use. My cost of fertilization is also dropping as I need much less to make my yard looking green! Love it.

This stuff works, our yard is about 20 by 40 and one bag does the trick, I put it on twice this summer so 2 bags for the entire warm season, love it
