Soil and Growing Media
Biochar for Soil and Growing Media Manufacturers
Improve water retention, nutrient retention, and soil structure in the soil products you make. Wakefield supplies biochar to established soil and growing-media manufacturers. From potting soils to compost blends, we help you select a carbon-rich ingredient that fits your formulation, handling equipment, and production needs.
How Biochar Helps
Build Better Soil Blends
Biochar adds lasting pore space to soil mixes and growing media, helping you build blends that manage water and nutrients for healthy plant growth.
Water Retention
Biochar can help blends hold moisture for roots, supporting healthy plants with less frequent watering.
Nutrient Retention
Biochar helps hold nutrients in the root zone where plants can use them, complementing the fertilizer, compost, and other ingredients in your blend.
Soil Structure
Biochar helps shape the balance of water and air in the root zone while providing habitat for beneficial soil microbes.
Made from wood residuals, biochar also brings stable, plant-derived carbon into your products. This renewable ingredient can support sustainability goals alongside the practical benefits of the finished soil blend.
Premium Biochar for Soil and Growing Media
- Organic Carbon: 85–95%
- Particle Size: ≥ 95% below 2 mm
- Moisture: 50–60%
Premium Biochar
Our primary starting point for potting soils, growing media, and tightly controlled blends. Premium Biochar offers higher carbon content and lower ash, giving manufacturers closer control over ingredient composition.
OMRI listed. Available in 2-cubic-yard bulk bags or loose truckloads.
Product values reflect typical material properties and may vary by lot. See each specification sheet for the full particle-size distribution and measurement details.
Biochar AG™
An economical alternative for broader soil, compost, and amendment blends that accommodate its higher ash content.
Premium Biochar LM™
A lower-moisture option when your blending process or finished-product requirements call for less incoming water.
Common Manufacturing Uses
Biochar Across Your Product Lines
Plan the Rate From the Finished Soil Mix
Start with approximately 5–10% biochar by volume of the finished soil mix. For a ready-to-use soil product, this is the biochar percentage in your blend.
For a concentrated amendment, calculate backward from its share of the finished soil. If your amendment makes up 20% of the finished mix and the target is 5% biochar, the amendment should contain 25% biochar: 20% × 25% = 5%. All percentages are by volume.
Learn more about choosing biochar for your formulation. Wakefield can help translate the finished-soil target into a manufacturing blend rate.
Facility Handling and Supply
Plan Delivery Around Your Facility
Choose bulk bags for facilities equipped to lift and unload them. Lifting straps and bottom discharge spouts help feed material into blending equipment.
Premium Biochar and Biochar AG also ship in loose truckloads. Plan for equipment to move, screen, or blend the material and stockpile space clear of roads and access routes.
For supply planning, share your product and intended use, trial and ongoing volume, production timing, delivery location, unloading equipment, and any specifications or testing requirements.

FAQ
Which biochar should we use in our soil blend?
Start with Premium Biochar for most potting soils, growing media, and controlled formulations. AG is an economical alternative where higher ash content fits the blend. Choose LM when incoming moisture needs to be limited.
How much biochar should the finished soil mix contain?
Start with approximately 5–10% biochar by volume of the finished soil mix. Adjust the formulation around your other ingredients and intended growing conditions.
How do we calculate the rate for a concentrated amendment?
Calculate backward from the amendment’s share of the finished soil mix. If your amendment makes up 20% of the finished mix and the target is 5% biochar, the amendment should contain 25% biochar: 20% × 25% = 5%. All percentages are by volume.
Can we request a sample?
Yes. Tell us about your soil product and any material requirements, and we’ll help identify a suitable sample for blend testing. Samples are generally paid, with shipping paid by the customer. Availability and costs are confirmed with your request.
What packaging and order sizes are available?
Standard bulk-bag orders typically start at one bag. Ordering several bags or a full truckload generally lowers freight cost per bag. Premium Biochar and Biochar AG are also available in loose truckloads. We can plan ongoing deliveries around your production needs.
What product documentation is available?
Product specifications and safety data sheets (SDS) are linked from each product page. For larger-volume supply arrangements, contact Wakefield to discuss Certificates of Analysis (COAs) and specific testing requirements.
