Old Cobblers Farm™ Wicked Organics Bio Char
How to use biochar to transform soil health, boost water retention, and improve nutrient efficiency. OMRI-listed organic amendment guide.
Old Cobblers Farm™ Wicked Organics Bio Char
Biochar is essentially charcoal made for agricultural use. The pyrolysis process creates a highly porous carbon material with an enormous surface area — up to 300 square meters per gram. This structure gives biochar three key properties: it holds water like a sponge, it traps nutrients that would otherwise wash away, and it provides habitat for the beneficial bacteria and fungi that drive soil health.
Biochar does not decompose the way compost or mulch does. Once applied, it persists in the soil for hundreds of years, continuously improving soil structure and fertility. This makes it a one-time investment in long-term soil health.
For best results, biochar should be 'charged' before application by mixing it with compost, worm castings, or liquid fertilizer. Fresh biochar can temporarily tie up nitrogen as it absorbs and fills its pores, so charging it first prevents any short-term nutrient deficit.

What Is It ?
Biochar is a carbon-rich soil amendment created by heating organic biomass (such as wood, crop residues, or agricultural waste) at high temperatures in the absence of oxygen — a process called pyrolysis. While biochar carries essentially no NPK value, it is one of the most powerful long-term soil improvement tools available to gardeners and farmers.
Biochar's magic lies in its microscopic structure: billions of tiny pores that act as homes for beneficial soil microorganisms, sponges for water and nutrients, and permanent reservoirs that prevent fertilizers from leaching out of the root zone. A single application of biochar can improve soil fertility for decades — possibly centuries — because the stable carbon structure resists decomposition.
Old Cobblers Farm™ Wicked Organics Bio Char is OMRI-listed for organic production and works in any soil type. It is especially transformative in sandy soils that struggle with water and nutrient retention, clay soils that need better drainage and aeration, and tired soils that need a microbial reboot.
When To Apply ?
Before applying, 'charge' biochar by mixing it 50/50 with finished compost and keeping it moist for 1-2 weeks. This fills the pores with nutrients and microbes, preventing temporary nitrogen tie-up. Broadcast 3-5 cubic feet of charged biochar per 100 sq ft and incorporate into the top 4-6 inches of soil. For containers, mix biochar at 5-10% by volume of potting media. For trees, mix into backfill soil at 10-20% by volume. Water thoroughly after application.
How to Apply ?
1.
Charge Biochar
Charge biochar by mixing with compost or liquid fertilizer for 1–2 weeks before use. Uncharged biochar can temporarily tie up nutrients.
2.
Calculate Rate
Calculate rate — 3–5 cubic feet per 100 sq ft for most soils. Sandy soils benefit from higher rates.
3.
Broadcast
Broadcast charged biochar evenly over the garden bed for uniform soil improvement.
4.
Incorporate
Work into the top 4–6 inches of soil with a tiller or spade for permanent root-zone enhancement.
5.
Water In
Water thoroughly to settle biochar into soil pores and begin moisture retention benefits.
6.
Long-Term Benefit
One-time application provides decades of benefits including improved water retention, microbial habitat, and nutrient holding capacity.
7
Broadcast
Broadcast charged biochar evenly over the garden bed for uniform soil improvement.
How To Store
Biochar is non-toxic and safe to handle. Dry biochar dust can irritate lungs — wear a dust mask and wet the material before spreading to reduce dust. Store in a dry location — dry biochar can be a fire hazard if exposed to sparks. Keep bags sealed to prevent moisture absorption before intentional charging.
FAQs
1.
What is biochar?
Biochar is a carbon-rich soil amendment produced by heating organic materials (wood, agricultural waste, or other biomass) at high temperatures in a low-oxygen environment — a process called pyrolysis. The result is a highly porous, stable form of carbon that persists in soil for hundreds to thousands of years. Biochar improves soil structure, water retention, nutrient-holding capacity, and microbial habitat. It is not a fertilizer itself but dramatically enhances how soil holds and delivers nutrients to plants. Old Cobblers Farm™ Wicked Organics Bio Char is a premium soil amendment for building healthier, more productive soil.
2.
What are the benefits of biochar for gardens?
Biochar delivers multiple soil-building benefits. Its highly porous structure increases water retention in sandy soils and improves drainage in clay soils. The massive surface area provides habitat for beneficial soil microorganisms, boosting biological activity. Biochar's cation exchange capacity helps soil hold onto nutrients like nitrogen, potassium, and calcium instead of letting them leach away. Over time, biochar-amended soils require less fertilizer and water while producing healthier, more productive plants. Old Cobblers Farm™ Wicked Organics Bio Char transforms ordinary soil into a nutrient-rich, moisture-holding growing medium.
3.
How do I use biochar in my garden?
Mix biochar into the top 6–8 inches of garden soil at a rate of 5–10% by volume. For best results, charge the biochar before use by soaking it in compost tea, liquid fertilizer, or worm casting extract for 24–48 hours — this pre-loads the porous structure with nutrients and beneficial microbes. Apply once, as biochar persists in soil for years without needing replacement. It can also be added to potting mixes, compost piles, and raised beds. Old Cobblers Farm™ Wicked Organics Bio Char is ready to use or charge for maximum soil-building impact.
4.
Does biochar help with water retention?
Yes, biochar significantly improves soil water retention. The highly porous structure acts like a microscopic sponge, absorbing and holding water that would otherwise drain away. Studies show biochar can increase soil water-holding capacity by 20–50% depending on soil type and application rate. This is especially valuable in sandy soils, raised beds, and drought-prone gardens where moisture conservation is critical. Plants in biochar-amended soil require less frequent watering and show greater drought resilience. Old Cobblers Farm™ Wicked Organics Bio Char helps gardens retain moisture naturally for healthier plants with less water.
5.
How much biochar should I add to soil?
Add biochar at a rate of 5–10% by volume of your soil. For a standard 4x8 raised bed filled to 12 inches deep, this is approximately 15–30 quarts of biochar. For in-ground gardens, incorporate 1–2 inches of biochar into the top 6–8 inches of soil. For potting mixes, replace 5–10% of the total volume with biochar. A little goes a long way because biochar persists in soil for hundreds of years — this is a one-time soil investment that keeps paying dividends. Old Cobblers Farm™ Wicked Organics Bio Char provides long-lasting soil improvement from a single application.
6.
Should I charge biochar before using it?
Charging biochar — soaking it in a nutrient-rich liquid before adding to soil — is highly recommended. Uncharged biochar can temporarily absorb nutrients from the surrounding soil as its pores fill up, which may briefly reduce nutrient availability to plants. Pre-charging with compost tea, diluted liquid fertilizer, or worm casting extract saturates the pores with nutrients and beneficial microbes so the biochar immediately contributes to soil fertility instead of competing for it. Soak for 24–48 hours before incorporating into soil. Old Cobblers Farm™ Wicked Organics Bio Char responds excellently to charging for maximum garden benefit.
7
Can I add biochar to my compost pile?
Yes, adding biochar to compost is one of the most effective ways to use it. The porous structure provides habitat for composting microorganisms, accelerating decomposition. Biochar also absorbs and retains nutrients released during composting that would otherwise leach out with rainfall. The finished compost-biochar blend is a supercharged soil amendment that delivers both nutrients and long-term soil structure improvement. Add biochar at 5–10% of compost pile volume. Old Cobblers Farm™ Wicked Organics Bio Char integrates seamlessly into composting systems for enhanced soil-building results.
