Are you tired of struggling to maintain a bountiful garden year after year? Do you find yourself constantly battling pests and disease, while your plants struggle to thrive?

If this describes you, it may be time to consider incorporating biochar into your gardening routine, just like we have.

Biochar is a form of charcoal that is produced by heating organic material, such as wood, to high temperatures in the absence of oxygen. The resulting material is rich in carbon and can be used to improve soil health and plant growth.

When added to soil, biochar can help to retain moisture, reduce nutrient leaching, and promote beneficial microbial activity.

But don't just take our word for it. According to a study published in the Journal of Environmental Quality, "biochar amendments have the potential to increase soil fertility, crop yield, and carbon sequestration, while also reducing greenhouse gas emissions and nutrient leaching." So if you're looking for a natural, sustainable way to improve your garden, consider giving biochar a try.

What is Biochar?

If you're new to gardening, you may be wondering what biochar is and how it can benefit your plants.

Simply put, biochar is a type of charcoal that is created by burning organic matter at high temperatures in a low-oxygen environment.

This process, called pyrolysis, results in a highly porous substance that is rich in carbon and other essential nutrients.

But why use biochar in your garden? Well, for starters, it can help improve soil quality in a number of ways. For one, it can help retain moisture in the soil, which can be especially beneficial for plants in hot, dry climates.

Additionally, it can help increase the soil's ability to hold onto nutrients, which can help reduce the need for synthetic fertilizers.

Another benefit of biochar is that it can help promote healthy microbial activity in the soil. This is important because soil microbes play a crucial role in breaking down organic matter and releasing nutrients that plants can use. By providing a hospitable environment for these microbes, biochar can help boost the overall health of your soil and, by extension, your plants.

It's worth noting that not all biochar is created equal. The quality of biochar can vary depending on the source material used to create it, as well as the specific conditions under which it was produced. As such, it's important to do your research and choose a high-quality biochar product that is specifically designed for gardening purposes.

Overall, biochar is a versatile and effective tool for improving soil quality and promoting healthy plant growth.

Whether you're a seasoned gardener or just starting out, incorporating biochar into your gardening routine is definitely worth considering.

Water Retention

Biochar has the unique ability to absorb and retain water, which can be especially beneficial in areas with low rainfall or during periods of drought.

In addition, biochar can help reduce soil erosion and runoff, which can improve water quality and prevent soil loss.

Nutrient Retention

Biochar can help retain nutrients in the soil by reducing leaching and increasing nutrient availability to plants.

This can result in healthier, more productive plants and reduce the need for synthetic fertilizers.

In addition, biochar can help reduce greenhouse gas emissions by sequestering carbon in the soil.

Overall, gardening with biochar can provide numerous benefits for both the environment and your plants. By improving soil health, increasing plant growth and yield, retaining water and nutrients, and reducing greenhouse gas emissions, biochar is an excellent addition to any gardener's toolkit.

How to Use Biochar in Gardening

If you're looking to improve your gardening game, biochar might be just what you need. Here's how to use it to get the most out of your garden:

Preparation

Before you start using biochar, it's important to activate it. Raw biochar can temporarily slow down plant growth by drawing nutrients and water away from the soil. To activate it, you'll need to inoculate it with nutrients and microorganisms. One way to do this is to mix it with compost or manure and let it sit for a few days to a few weeks. This will help the biochar absorb the nutrients and microorganisms it needs to benefit your soil.

Importance of Inoculation

Inoculating your biochar is an important step because it helps to prime your soil for improved fertility. By adding nutrients and microorganisms to your biochar, you're giving your plants the best possible chance to thrive. Without inoculation, your biochar won't be as effective at improving your soil's health.

Maintenance

Using biochar in your garden is a long-term investment in your soil's health. You won't see immediate results, but over time, you'll notice that your soil is healthier and your plants are happier.

Since it’s expensive and time consuming to apply all at once, to continue increasing the benefits of biochar in your soil, you'll want to keep some handy and continue to add it to your soil on a regular basis. Aim to add a few handfuls of biochar to your garden beds or containers every year to keep your soil healthy and constantly thriving and improving.

Application

Once your biochar is activated, you can apply it to your garden in a few different ways. One option is to mix it into the soil in your garden beds. Another option is to add it to your potting mix when you're planting in containers. You can also use biochar as a top dressing by sprinkling it over the surface of your soil. However you choose to apply it, be sure to work it into the soil so that it can make contact with your plants' roots.

Broadcast Application

Parallel Strip Application

If you want to apply the biochar over the entire garden, but have a large area to cover which is cost prohibitive, you can apply biochar in strips, with the intention of repeated continued application each year.

Simply apply the biochar in 5 or 6” wide strips and incorporate, with the strips being separated by 5 or 6”.

The next year, apply the biochar again but where the biochar was not applied the previous year.

Further applications can use the same technique but be at right angles to the first set of applications.

If you plant your plants into the inoculated strips, you will get the benefits of the biochar without needing to apply it to the entire garden.

In Row Application

Planting Hole Application

Mixed Application

This method can take the form of a light surface broadcast across the entire garden bed, followed with a higher application rate where the plants will be planted, either in-row for direct seeded row crops or in the planting hole for transplanted crops or crops planted in hills (such as squash).

This will provide some benefit to the entire bed, while also providing more benefit to your plants to get them off to a good start.

Types of Biochar

When it comes to gardening with biochar, there are a few different types to choose from. Each type has its own unique properties and benefits. In this section, we'll take a closer look at the three main types of biochar: wood-based, agricultural waste-based, and animal waste-based.

Wood-based Biochar

Wood-based biochar is made from pyrolyzing wood at high temperatures. This type of biochar is popular because it is readily available and easy to produce. It is also relatively low in heavy metals and other contaminants, making it a safe and effective choice for gardening.

One of the benefits of wood-based biochar is that it has a high carbon content, which can help to improve soil fertility and structure. It can also help to reduce soil acidity, which is beneficial for plants that prefer a more neutral pH.

Some common types of wood-based biochar include pine, oak, and maple.

Whatever type you choose, it’s important that the biochar is fired at hot enough temperatures to drive off any oils and tars: those hand-blackening compounds that you need to wash off your hands when handling BBQ charcoal.

You can quickly test this by picking up some biochar and rubbing it between your fingers. If your fingers come mostly clean under running water, the biochar was fired at a hot enough temperature.

Agricultural Waste-based Biochar

Agricultural waste-based biochar is made from the pyrolysis of agricultural waste products, such as corn stalks, rice husks, and sugarcane bagasse. This type of biochar is popular because it is a sustainable choice that helps to reduce waste and improve soil health.

One of the benefits of agricultural waste-based biochar is that it can help to increase soil porosity, which can improve water retention and reduce soil erosion. It can also help to reduce nutrient leaching, which is beneficial for plants that require a lot of nutrients.

Agricultural Waste biochar is not as dense as wood-based biochar, so it may tend to break down faster in the soil.

Some common types of agricultural waste-based biochar include rice husk biochar and sugarcane bagasse biochar.

Animal Waste-based Biochar

Animal waste-based biochar is made from the pyrolysis of animal waste products, such as chicken manure, cow manure, and horse manure.

One of the benefits of animal waste-based biochar is that it can help to increase soil fertility as it may contain more minerals and nutrients than other kinds of biochar. Like other kinds of biochar, It can also help to reduce soil compaction, which is beneficial for plants that require good soil aeration.

Some common types of animal waste-based biochar include chicken manure biochar and cow manure biochar.

One potential drawback with manure-based biochar is they may contain a higher percentage of toxins if the animals were exposed to any heavy metals in their feeds. This is due to the fact that the animals will concentrate nutrients in their manures.

Where to Get Biochar

Now that we know what biochar is and how it can benefit our garden, the next step is to get our hands on some. There are two main ways to obtain biochar: purchasing it or making it at home.

Purchased Biochar

If you're looking to purchase biochar, there are a few things to consider. First, make sure you're buying from a reputable source.

Look for companies that specialize in biochar production and have a good track record. You can also check with your local garden center or agricultural supply store to see if they carry biochar.

When purchasing biochar, pay attention to the type and quality. Different types of biochar can have varying effects on soil health and plant growth. Make sure you're getting the right type for your specific needs. Additionally, look for biochar that has been properly processed and is free of contaminants.

Also make sure you have a plan in place to spread the biochar. A very fine, dusty biochar may be best spread in the irrigation water while a more pelletized version may be best spread with a broadcast spreader.

Finally, consider the cost. Biochar can be expensive, so make sure you're getting a good value for your money. Compare prices from different sources and read reviews from other gardeners to get an idea of the quality and effectiveness of different brands.

Home-Made Biochar

If you're feeling adventurous, you can also make your own biochar at home. This can be a fun and rewarding DIY project, and it's a great way to recycle organic waste from your garden.

To make biochar at home, you'll need a container that can withstand high temperatures, such as a metal drum or ceramic kiln. You'll also need a source of organic material to burn, such as wood chips, sawdust, or agricultural waste. It’s important that this feedstock be dry.

There are many different methods for making biochar at home, but the basic process involves heating the organic material in a low-oxygen environment until it turns into charcoal. This can take several hours, so be prepared to monitor the process carefully.

Once you have your biochar, it's important to "activate" it before using it in your garden. This involves adding nutrients and microorganisms to the biochar to help it break down and release its beneficial properties. There are many different methods for activating biochar, so do some research to find the one that works best for you.

Whether you choose to purchase biochar or make it at home, incorporating this amazing substance into your garden can have a big impact on soil health and plant growth. So why not give it a try and see the results for yourself?
