Introduction to Biochar and This Series

Hi, I’m Paul Morris, a restoration ecologist. My partner, Sophia Ortiz, is an agronomist. Together, we’ve spent years working with communities to regenerate ecosystems, restore degraded lands, and apply practical, low-cost methods for healing the Earth.

In this guide, we’ll focus on biochar—what it is, how to make it, how to use it, and why it’s so valuable. This is the written version of a video series we created to make the process accessible to anyone, whether you're on a small farm or in a rural village or want to do something good for your garden and the health of your soil.

We'll show you how to make biochar using different methods. Our first episodes focus on using a Kon-Tiki kiln and an oil barrel system, both of which can be built or adapted with materials available in most places.

These methods don’t require big machines or expensive inputs. They’re based on simple, replicable designs that turn waste biomass into something regenerative—carbon-rich, soil-enhancing, and locally valuable.

As you read this guide, you'll find a blend of practical instructions, scientific insights, and global examples. Each chapter is crafted to help you take action immediately and understand how your efforts fit into the bigger picture of ecosystem restoration and land stewardship.

Let’s begin our journey by looking at biochar and why it matters.

Ash forms when oxygen interacts with the carbon. We want the carbon, not ash!

Chapter 1: What Is Biochar and Why Does It Matter

What is Biochar?

Biochar is a stable, carbon-rich substance made by heating organic material (biomass) in a low-oxygen environment—pyrolysis. Unlike ash, which is the mineral residue left after complete combustion, biochar retains the carbon and much of the cellular structure of the original material.

Biochar locks carbon in a solid form that resists decay, potentially for hundreds or even thousands of years. This makes biochar valuable for soil improvement and a powerful tool for carbon sequestration.

Historical Context

Long before the word "biochar" was coined, Indigenous communities practiced it. The most famous example is the Amazon Basin, where Indigenous peoples created "Terra Preta"—literally "dark earth"—by adding charcoal, pottery shards, and organic waste to poor tropical soils. These soils are still fertile today, centuries later.

Terra Preta inspired modern biochar research. What was once considered a curiosity is now a globally significant climate and soil solution.

Glaser, B., Lehmann, J., & Zech, W. (2002). Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal: a review. Biology and Fertility of Soils, 35(4), 219-230.

Why Biochar Matters

Soil Health Improvement

Increases soil structure and porosity
Enhances water retention
Reduces soil acidity
Provides a habitat for beneficial microbes
Improves nutrient retention and reduces leaching

Carbon Sequestration

Locks atmospheric carbon in a solid, stable form
Can remain stable in soil for hundreds to thousands of years
Contributes to climate change mitigation

Waste Management

Converts agricultural and forestry waste into a valuable resource
Reduces methane emissions from organic matter decomposition
Can help manage invasive species or excessive biomass

Economic Potential

Can improve crop yields and reduce fertilizer needs
Emerging markets for biochar and carbon credits
Potential for community-scale biochar enterprises

*** Caution: Use waste material for biochar. Organic matter can be composted and added to the char. Never cut a forest to get material. ***

Recent Research and Innovations

Recent studies have shown that biochar can:

Reduce nitrous oxide (N2O) emissions from fertilized soils (Cayuela et al.,

Enhance crop yields in degraded soils (Jeffery et al., 2017)
Improve soil microbial diversity and stability (Lehmann et al., 2011)

Key Takeaway

Biochar is more than just blackened wood—it’s a multifaceted tool with the power to regenerate soils, capture carbon, reduce waste, and empower regenerative economies. Understanding its full potential starts with understanding its origin, structure, and wide-ranging benefits.

Next, we’ll explore the science of how biochar works in soil.

Chapter 2: How Biochar Works in Soil

The Physical Structure of Biochar

Biochar has a highly porous structure, similar to activated carbon. These pores range from macro to micro in size, creating a vast surface area. One gram of biochar can have a surface area exceeding 300 square meters.

This structure allows it to:

Retain water like a sponge
Hold onto nutrients and prevent leaching
Provide a habitat for beneficial soil organisms

The porosity and surface area vary depending on the feedstock used and pyrolysis temperature. High-temperature biochar tends to have more surface area but lower nutrient content.

Crushing or grinding the biochar fine is essential for increasing the surface area

Downie, A., Crosky, A., & Munroe, P. (2009). Physical properties of biochar. In Lehmann & Joseph (Eds.), Biochar for Environmental Management.

Grinding biochar for a ne application. Note the moisture coming out of the carbon.

Biochar’s Chemical Properties and Soil Interactions

pH buffering: Most biochars are alkaline and can help neutralize acidic soils.

Cation exchange capacity (CEC): Biochar can retain positively charged

ions like potassium, calcium, and magnesium, making them available to plants.

Adsorption of contaminants: Biochar can bind heavy metals and organic

pollutants, reducing their mobility in the soil. These chemical interactions help create more resilient, nutrient-efficient soils that require fewer inputs.

Novak, J. M., et al. (2009). Impact of biochar amendment on fertility of a southeastern Coastal Plain soil. Soil Science, 174(2), 105–112.

Microbial Life and Biochar

Biochar improves soil chemically and physically and provides a thriving habitat for microbes. Its pore structure protects microbial colonies and allows them to form stable biofilms.

Supports nitrogen-fixing bacteria
Promotes mycorrhizal fungi colonization
Helps maintain microbial diversity

Over time, biochar becomes “charged” with microbial life, improving nutrient cycling and disease resistance.

Lehmann, J., & Rondon, M. (2006). Bio-char soil management on highly weathered soils in the humid tropics. Biological Approaches to Sustainable Soil Systems.

Interaction with Organic Matter

Biochar interacts synergistically with compost, manure, and cover crops:

Enhances compost stability
Reduces greenhouse gas emissions from composting
Stimulates humus formation in soil

Adding biochar to organic matter systems creates a more stable and fertile soil layer over time.

Steiner, C., et al. (2010). Nitrogen retention and plant uptake on a highly weathered central Amazonian Ferralsol amended with compost and charcoal. Journal of Plant Nutrition and Soil Science.

Summary: Why Biochar Is a Soil Supercharger

Biochar improves soil on multiple levels:

Structurally: improving aeration and water holding
Chemically: enhancing nutrient availability and pH
Biologically: supporting microbial and fungal networks

It helps regenerate degraded land, increase yields, and reduce fertilizer dependency when used appropriately.

Next, we’ll examine how biochar is made—and how different methods affect its properties.

Chapter 3: Biochar Production Methods – An Overview

What Is Pyrolysis?

Pyrolysis is the decomposition of organic material at high temperatures in the absence (or near absence) of oxygen. This thermal decomposition produces three main products:

Biochar (solid)
Bio-oil (liquid)
Syngas (gas)

The ratio of these products depends on the temperature, duration, and feedstock us

Slow pyrolysis (350–550°C)
Maximizes biochar yield
Takes longer (hours)
Common for small-to medium-scale biochar production
Fast pyrolysis (450–600°C)
Prioritizes liquid bio-oil production
Yields less biochar (~10–15%)
Used primarily for energy production

Choosing the Right Feedstock

Good biochar starts with good feedstock. Options include:

Woody biomass (e.g. branches, sawdust, bamboo)
Crop residues (e.g. corn stalks, rice husks, sugarcane bagasse)
Animal manures (less common due to high ash content)

Avoid: treated wood, plastics, or waste with chemical residues.

Feedstock affects:

Nutrient content (e.g. potassium, phosphorus)
Porosity

pH of final biochar

Enders, A., et al. (2012). Characterization of biochars to evaluate recalcitrance and agronomic performance. Bioresource Technology, 114, 644–653.

Note: Make sure the material is dried well. The white smoke at the beginning of a burn is water vapour, which lowers the burn temperature.

Temperature and Time Matter

Lower temperatures produce higher yields but less porous biochar
Higher temperatures increase surface area and carbon stability
Holding time (duration at peak temperature) affects chemical structure

For soil use, 400–550°C is generally optimal.

Safety and Emissions Considerations

Incomplete combustion can release harmful smoke and particulates
Well-designed kilns minimize emissions (see Kon-Tiki and TLUD)
Always operate outdoors or with proper ventilation

In the next chapter, we’ll explore specific DIY methods for making biochar at home or in small-scale community settings—each with pros and cons and practical tips.

Chapter 4: DIY Biochar Techniques (Small Scale)

Pit Method

Overview: One of the oldest methods involves digging a pit and burning biomass in layers with limited oxygen.

Very low cost
No equipment needed
Easy to implement with basic tools
Difficult to control air flow and burn
Higher emissions
Inconsistent biochar quality

Best For: Rural areas with limited resources and abundant biomass.

Top-Lit Updraft (TLUD) Stoves

Overview: A cylindrical stove where biomass is lit at the top and burns downward, limiting oxygen and promoting pyrolysis.

Cleaner burn
Efficient and portable
Produces usable heat while making biochar
Small batch sizes
Needs dry, uniform feedstock

Resources: Open-source TLUD designs available from biochar-international.org

Barrel Retort System

Overview: This system involves a sealed barrel (inner chamber) with biomass surrounded by another barrel or re pit to heat it externally.

More control over temperature
Better quality and consistency
More complex to build
Slower batch processing

Best For: Homesteads, farms, and permaculture settings.

Kon-Tiki Flame Curtain Kiln

Overview: A conical metal or earthen kiln where biomass is added in layers as it burns, forming a clean-burning flame curtain.

High efficiency, low emissions
Handles large volumes
Simple to build
Requires supervision during burn
Weather-sensitive (wind and rain)

Resources: Detailed plans at ithaka-institut.org

Ortiz Method: Open-Top Oil Barrel Kiln (Modified Kon-Tiki Style)

This is the method we often use in our projects. It's a low-cost, highly replicable system based on the Kon-Tiki flame curtain kiln principles but made using a single 200-litre oil drum. It's ideal for areas with limited access to tools, materials, and funds.

How it works:

The barrel is set upright with an open top and has no holes in the barrel. Biomass is added and lit at the bottom of the barrel.

When the fire is going well, layers of material are added and burned until

we see ash starting to form

Another material layer is added and burned; the lower layer has no

oxygen as the burn is above and does not turn into ash. Keep adding layers, repeating the process until the barrel is near the top with carbon.

We add smaller, fast-burning material near the end of the burn to give

more time for the lower layers to burn thoroughly to char while keeping oxygen out.

The top burns, creating a clean flame that consumes smoke while the

lower layers char.

The fire is quenched with water once the barrel is nearly full and the

flames die down.

When scaling up, you add more barrels burning at the same time. Two

people can manage three burning barrels, which produce a lot of char quickly.

What makes this different:

No inner barrel (not a retort system)
No welding required
Simple modifications anyone can do with a chisel and hammer to open

the top

Extremely affordable and accessible
Lower smoke emissions than a pit kiln
Ideal for teaching and demonstration
Requires supervision during the burn
Best suited for dry, uniform woody biomass

In the next chapter, we’ll explore how to charge and activate biochar—transforming it from inert carbon into a living soil amendment rich in nutrients and microbes.

Chapter 6: Charging and Activating Biochar

Why Charging Is Essential

Freshly produced biochar is often called “raw” or “inert.” When applied directly to soil without nutrients, it can temporarily bind nutrients like nitrogen, leading to plant deficiencies. This is called nutrient tie-up.

Charging biochar means loading it with nutrients and beneficial microorganisms before it’s added to the soil. This process transforms it into a bioactive amendment ready to support soil fertility.

Breaking up the large chunks to increase surface area and make it easier to apply

Composting with Biochar

One of the most effective ways to charge biochar is to add it to compost:

Benefits:

Enhances microbial colonization
Absorbs nutrients during decomposition
Reduces odors and emissions from compost

Typical Blend:

5–15% biochar by volume in compost piles

Tip: Add biochar early in the composting process for best results.

Reference:

Schmidt, H.-P., et al. (2014). Biochar in composting for nutrient retention and odor control. Agronomy.

Charging larger amounts of biochar

Liquid Nutrient Charging Methods

Biochar can also be soaked in liquid nutrient solutions. This is faster than composting and ideal for small batches.

Common Soaking Liquids:

Compost tea
Worm castings tea
Fermented plant juice
Fish emulsion
Effective Microorganisms (EM)

Soaking Time:

1 to 2 weeks for full saturation

Ratio:

1 part biochar to 2–4 parts liquid

Formulas for Biochar Blends

Note: Moisture is key to supporting microbial colonization.

Various soil microbial mixes can be bought, but local microbes are better to use by cultivating your own

Nursery mix of native soil with biochar - white nodules are nitrogen-fixing bacteria

Quick Guide to Making Biochar:

Add brush to barrel (top open and no other holes for pyrolysis) and light

Add layers of brush as lower layers burn down, but before ash forms

On the last few layers, use smaller brush to ensure an even burn

Fill the barrel with water to halt the burning process

Add 10 L of urine to charge the char with nitrogen and leave overnight

Drain any water that has not been absorbed, and spread the char out in an even layer

Crush down any larger pieces using a carpet roller or something of the sort

Turn in manure, soil and compost (or whatever is available), 50% char to 50% organics

Pour on diluted Super Brew organic fertilizer mixture (Super Powerful Brew video

https://www.youtube.com/watch?v=rBnsiuKs7Ic)

You can also enhance the microbiome by locally collecting and propagating it and adding it to the mix (Microbiome Collection and Use: https://www.youtube.com/watch?v=jsMlk5M5PM4)

Cover with a tarp and let sit for 3 months to break down and infuse into biochar.

Bag up and use!

Tip: Charging is not optional—it’s a foundational step to unlock the full potential of biochar.

In the next chapter, we’ll look at how to apply biochar in different contexts and create specialized blends tailored to soil types and crops.

Chapter 7: Biochar Recipes and Application Strategies

Different Formulas for Different Soils

Sandy Soils:

Add 10–20% biochar by volume to improve water and nutrient retention. Blend with compost or manure to enhance fertility. Clay Soils:

Mix 5–10% biochar to improve aeration and drainage. Combine with gypsum or compost for optimal structure. Acidic Soils:

Use alkaline biochar (wood-based, high-temperature)
Apply up to 20% biochar to help raise pH gradually

Degraded or Eroded Soils:

Apply 10–30% biochar mixed with compost, rock dust, and mulch
Incorporate cover cropping and re-mulching strategies

Garden application - In Canada, sandy soil: Solarized soil, not tilled, biochar layer added, then a thick layer of composted leaf mulch. In one year, worms and soil microfauna will mix the biochar into the soil for you.

After that, a layer of clean cardboard and then composted woodchips was put on the pathways to suppress weeds, hold moisture, and release nutrients as they broke down.

In Mexico, we built beds to enhance the poor soil with 50% biochar

Local Mayan corn grown in the biochar beds, Yucatan. Our neighbour who gave us the seed had half the size.

He was amazed!

Tip: Always pre-wet or pre-charge biochar before incorporation into soil. When fully dry, the char is hydrophobic (repels water).

Co-Composting Ratios and Timing

Co-composting improves nutrient retention and inoculation.

Best Practice:

Mix biochar in during the initial compost pile formation
Maintain moisture and turn regularly
Typical compost mix: 60% green, 30% brown, 10% biochar

Timing:

Minimum 4–6 weeks composting time with biochar
Longer composting enhances nutrient saturation and microbial activity

Reference:

Hagemann, N., et al. (2017). Organic coating on biochar enhances its positive effects in plant-soil systems. Frontiers in Plant Science.

Note: Raw char can also be added to animal bedding and will reduce smells and get mixed in with the manure

Case Studies with Application Rates

Case: Nepal Hillside Farming

Mix of 20% rice husk biochar + compost
