Your soil is working against you
Compacted, Lifeless Soil
Clay soil compacts into brick. Sandy soil drains too fast. Either way, roots struggle, water runs off or through, and your plants never reach their potential — no matter how much fertilizer you add.
Fertilizer That Doesn't Stick
Without soil structure to hold nutrients, fertilizer leaches away with every rain or irrigation cycle. You're feeding the storm drain, not your plants. The money you spend on inputs washes away — literally.
Dead Microbial Life
Healthy soil teems with beneficial microorganisms that cycle nutrients, suppress disease, and build organic matter. Years of synthetic inputs, compaction, and neglect leave soil biologically barren.
How It Works
| Feature | What It Means for You |
|---|---|
| High-quality biochar | Porous carbon structure creates millions of microscopic pores that hold water, air, and nutrients in the root zone |
| Infused with humic acid | Humic acid chelates nutrients and makes them more available to plant roots — biochar plus humic acid is more effective than either alone |
| Permanent soil structure improvement | Unlike compost that decomposes, biochar persists in soil for hundreds of years — a one-time investment that keeps paying |
| Microbial habitat | The porous surface of biochar provides shelter and food sources for beneficial bacteria and fungi that drive soil health |
| Carbon sequestration | Every application locks carbon into the soil instead of releasing it into the atmosphere — better soil and a smaller footprint |
Application: Soil incorporation or top-dressing
Gardens and raised beds: • Mix 5-10 lbs per 100 sq ft into the top 4-6 inches of soil • Best applied before planting or during bed preparation • Can be mixed with compost for added benefit Lawns: • Apply 3-5 lbs per 100 sq ft as a top-dressing • Rake or water in after application • Pair with overseeding for best results Container plants: • Mix at 10-15% of total potting soil volume • Combine with quality potting mix Note: Biochar works best when "charged" — pre-mixed with compost, humic acid (already included in C-Fix), or liquid fertilizer before application.
Why Biochar Is Different From Everything Else You Add to Soil
Compost breaks down. Fertilizer washes out. Biochar stays. When you work C-Fix into your soil, you’re making a permanent structural improvement. The porous carbon matrix creates millions of tiny pores that hold water, trap nutrients, and provide habitat for the beneficial microorganisms that drive soil health. It’s not an input you reapply every season — it’s an upgrade that compounds over time.
The Humic Acid Advantage
Most biochar products require a “charging” period where the raw biochar absorbs nutrients from the soil before it starts giving them back. C-Fix skips that step. By infusing the biochar with humic acid during production, every granule arrives ready to work — chelating nutrients, feeding microbes, and improving nutrient availability from day one.
Where to Use It
C-Fix works in any soil, in any setting. Mix it into raised beds before planting. Top-dress your lawn during renovation. Blend it into container potting mix. Work it into clay soil to improve drainage, or into sandy soil to improve retention. Wherever soil needs help, biochar provides the permanent foundation that makes every other input work better.

I worked C-Fix into my raised beds last spring and the difference was obvious by midsummer. Better water retention, healthier root systems, and I used about 30% less fertilizer. It's a one-time investment that just keeps working.
Frequently Asked Questions
What is biochar?
Biochar is a form of carbon created by heating organic material (wood, agricultural waste) in a low-oxygen environment. The result is a highly porous, stable carbon structure that improves soil when incorporated. Unlike compost, biochar doesn't decompose — it persists in soil for centuries.
Why is C-Fix infused with humic acid?
Raw biochar can temporarily bind nutrients as it 'charges' in the soil. By pre-infusing C-Fix with humic acid, the biochar arrives ready to work — the humic acid chelates nutrients and makes them immediately available to plants, eliminating the charging period.
How much C-Fix do I need?
For garden beds, use 5-10 lbs per 100 square feet mixed into the top 4-6 inches. For lawns, apply 3-5 lbs per 100 sq ft as a top-dressing. A little goes a long way because biochar is permanent — you only need to apply it once per area.
Can I use C-Fix with other Southland soil products?
Absolutely. C-Fix pairs well with Genesis soil activator and Humates. The biochar provides structure and habitat, while the biological products populate that habitat with beneficial microorganisms.
Does biochar work in clay soil?
Yes. In clay soil, biochar improves drainage and aeration by creating pore space that breaks up compaction. In sandy soil, it does the opposite — holding water and nutrients that would otherwise drain away. It improves both extremes.
