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!.
