Some basic tips for using biochar

Biochar is a powerful tool for improving soil health and productivity. However, like any tool, it must be used correctly to enjoy its full benefits. Here are some simple tips to make the most of your biochar.

First, know what your garden needs. Whilst an application of a good quality biochar is likely to be good for your garden, if only because it creates a wonderful habitat for the microbiome (bacteria, fungi and worms); if you know what your garden is deficient in, you can select the appropriate biochar/ compost for the soil. Knowing the pH of the soil will help.

Second, not all biochars are the same. Key considerations are:

• The feedstock material is important, there is a big difference between a poultry manure and a wood biochar,
• the way the feedstock is processed is important, it cannot be too wet, too large and be a consistent size,
• the pyrolysis temperature and duration of burn will determine how good the biochar will be for your garden.

It’s essential to choose high-quality biochar that’s has been prepared and processed well. Understand how your biochar has been prepared.

Third, how much is too much? In brief, it is better to apply biochar little and often. This means you can then monitor the results before committing too applying too much in one go.

And finally, whilst high-quality biochar can be relatively expensive, in the long-term the benefits to your plants and soil will outweigh the investment.

By taking the time to consider which biochar suits your garden, you will get the most from using it.  productivity.
