What Is Biochar & How It Works
Biochar is a carbon-rich soil amendment created by heating organic biomass—such as wood waste or agricultural byproducts—in a low-oxygen environment through a process called pyrolysis. This process locks carbon into a stable form, producing a lightweight, highly porous material that can remain active in soil for hundreds to thousands of years.
 
Unlike compost, which breaks down over time, biochar acts as a long-term soil conditioner, improving soil performance season after season.
 
How Biochar Works in Soil
Biochar’s effectiveness comes from its microscopic pore structure. Each particle contains millions of tiny cavities that function like a sponge and storage system within the soil profile.
When incorporated into soil, biochar helps to:
Retain water more efficiently, reducing irrigation needs
Hold nutrients in place, preventing leaching during rain or watering
Improve soil aeration, especially in compacted or clay-heavy soils
Support beneficial microbes, creating healthier biological activity
Stabilize soil structure, improving root development and plant resilience
Because biochar itself is chemically stable, it does not burn roots or overload soil with nutrients. Instead, it enhances the performance of existing soil, compost, and fertilizers, making them more effective.
 
Why Biochar Is Different From Compost
Compost feeds plants directly by adding organic nutrients. Biochar, on the other hand, improves the soil system itself. When used together, biochar and compost create a powerful combination—compost provides nutrients, while biochar stores and delivers them efficiently over time.
 
This makes biochar especially valuable in Bay Area soils, where drainage, compaction, and nutrient loss are common challenges.
 
Common Uses & How to Apply Biochar
Biochar is extremely versatile and can be used across a wide range of residential, commercial, and agricultural applications throughout the Bay Area.
 
Home Gardens & Raised Beds
Biochar improves soil structure, increases water retention, and helps nutrients stay available longer—ideal for vegetables, herbs, flowers, and fruit trees.
 
Landscaping & New Plant Installations
When mixed into planting soil during installation, biochar reduces transplant shock and supports healthier root establishment for shrubs, trees, and perennials.
 
Lawns & Turf Areas
Biochar enhances soil aeration beneath turf, improves water efficiency, and supports microbial activity for stronger, more resilient lawns.
 
Vineyards, Orchards & Agricultural Soil
Widely used in regenerative agriculture, biochar helps stabilize nutrients, improve soil biology, and reduce irrigation demand—especially valuable for long-term crop health.
 
Soil Remediation & Poor Soil Conditions
Biochar is effective in depleted, compacted, or previously disturbed soils, helping restore structure and biological balance over time.
 
How to Apply Biochar
Biochar is most effective when blended with soil or compost rather than applied alone.
Recommended Application Rates (General Guidelines):
5–10% by volume when mixed into soil or compost
1–2 inches blended into the top 6–8 inches of soil
Often combined with compost, manure, or organic soil blends for best results

Biochar FAQs
Q. What is biochar used for?
Biochar is used to improve soil structure, increase water retention, reduce nutrient loss, and support beneficial microbial activity. It is commonly applied in gardens, landscaping, vineyards, orchards, lawns, and agricultural soils throughout the Bay Area.
 
Q. Is biochar better than compost?
Biochar and compost serve different purposes. Compost provides nutrients, while biochar improves the soil’s ability to retain those nutrients over time. When used together, they create a highly effective soil system that supports long-term plant health.
 
Q. How long does biochar last in soil?
Biochar is extremely stable and can remain active in soil for decades or longer. Unlike compost or mulch, it does not break down quickly, making it a long-term investment in soil health.
 
Q. Can biochar be used in raised beds and containers?
Yes. Biochar is excellent for raised beds and planters when blended properly with soil or compost. It helps prevent compaction, improves drainage, and supports consistent moisture levels.
 
Q. How much biochar do I need?
Most projects use biochar at 5–10% of total soil volume. The exact amount depends on soil type, project size, and application. North Bay Materials can help you estimate the right quantity for your specific project.
