The Andersons HumiChar Organic Soil Amendment with Humic Acid and Biochar (40 lb)

I have very poor soil that was imported to raise my yard to correct drainage. The trouble is that this imported fill was garbage. Basically hard pan. Grass has always done very poorly. Barely surviving. Fertilizer had minimal affect over the last three years. Was at my wits end. Tried this stuff. BAM lush green lawn for the first time. I went with a heavy application two months apart. My lawn is now at 90% perfection. Somehow this stuff helps the roots absorb fertilizer nutrients. I'm on auto ship with this stuff now. Not cheap, but it turned my backyard around, making it a paradise whereas before it was just an ugly eye sore with anemic grass and thriving weeds.

The best product of Andersons. My grass is completely green. This is not the first time using this product. I will recommend if you want to keep you grass green.

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

While an expensive product, it seems to be working as intended. I can get two applications with a single bag, for my property. Keeping my soil in good condition for my Zoysia is what needs to happen, for me.

For the $5 you save...it is not with the headaches of delays or busted boxes/bags!! Apparently they can't carry 40lbs. Or don't want to use cart!! Great products... Bad delivery service from Amazon! Three trucks in one small neighborhood is not efficient!!

We use this in the yard and improve the soil for grass, as well as the flower bed. We had a spot of compacted soil that nothing would grow for quite a while. I sprinkled down Humichar and worked into the soil. Now have plants growing there when everything a few months ago would die.

I am a huge fan of all the Anderson's products and apply HumiChar to my Bermuda lawn at the max recommended amount four times per year during the growing season. The soil where we live is heavy clay and the HumiChar helps the foil retain nutrients and over time the Humic Acid helps break down the clay as it mixes with the existing soil.

Great soil enrichment product but do not apply this product when a series of consecutive rainy days will follow after application of the product.

Item is great but pricy
