## Description

humichar

Review: 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.
Review: 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!

### ⭐⭐⭐⭐⭐ Review
*by J***K on 26 March 2025*

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
