What is Biochar?
If you’re involved in the gardening or agricultural scene, you might already be on the biochar bandwagon. It’s that charcoal-looking substance that gives gardens extra flair. Recently, we had a yarn with Michael over at Two Birds Landscaping and Environmental Solutions about the wonders of biochar.

What is biochar?
From cultural burning to burying charcoal in the Aztec era to now, Biochar is enjoying a modern revival. Biochar is the carbon-rich material produced from heating biomass in the absence of oxygen. Two Birds Landscaping make their own biochar using the wood waste from other landscaping projects. However, it can also be made from agricultural waste products, municipal green waste and animal manure.
What are the benefits of using biochar?
As for environmental benefits, biochar has become hugely popular for its role in climate change relief. It has the potential to retain carbon for years that might otherwise end up in the atmosphere as greenhouse gas emissions. Furthermore, the production of biochar co-generates biofuel (a sustainable renewable energy source). And as for the benefits in your backyard, it can extend the life of your fertiliser as well as increase the water storage capacity for your soil. Nice!

What is biochar used for?
Not only is it a great way to make the greenery in your garden look extra lush, but biochar also has a stack of other uses. From water treatment in fish farming to building insulation to macro-filters for drinking water in developing countries, the uses for biochar are endless. Another cheeky use that Michael shared with us is that biochar is great for eliminating the stink emanating from your kitchen compost bin.
So if you’re looking to use biochar in your next landscaping project or if you’re just looking for some advice on lowering your carbon footprint in your garden, have a chat with Michael over at Two Birds Landscaping and Environmental Solutions.
