What is biochar?

The oldest new thing you've never heard of


What is biochar?

The earliest known use of biochar was by the pre-Columbian indigenous people of the Amazon over 2,000 years ago. Their practice of creating biochar was discovered when scientists tested how the soil remained rich for over eight hundred years even though there were no plants growing in the soil. Biochar is a high-carbon form of charcoal that is produced by heating organic matter, in the absence of oxygen, a process called "pyrolysis" and because of the purity it doesn't degrade so it is a permanent improvement to your soil.

Biochar permanently locks carbon into the ground, rather than releasing harmful CO2, into the atmosphere, so not only can you make a permanently improvement to your soil health, but you are simultaneously improving your carbon footprint.

By using Carbon Gold biochar products, you can bring a physical and permanent change to your soil, improving structure, aeration, water-hold capacity, and nutrient retention. Biochar has a honeycomb structure that acts as a refuge by the beneficial microbiology which we add to improve plant health.  The means that they do not get leached by rainfall and are permanently available to your plants when they need them. It also acts like a series of mini reservoirs retaining water so, even in times of drought, you don’t have to water as often as you would without the addition of biochar.

In short, using Carbon Gold biochar is good for your garden and good for our planet!

Benefits of Enriched Biochar

Easy to Use

It's easy to apply and, because of its water holding qualities, it means less maintenance of plants, crops and lawns. It also means you'll save a bit on those water bills.

Permanent Effects

Biochar is so high in carbon that it doesn't break down over time, meaning one application is all you need to permanently improve your soil.

Environmentally Friendly

1 tonne of biochar in the ground is the equivalent of 3 tonnes of carbon dioxide permanently sequestered from the atmosphere!

Improves Plant Health

Enriched biochar is proven to boost the health and vitality of nearly every type of plant, and healthier plants are stronger and more productive!
