BIOCHAR – How to make Biochar to improve your soil

Said to have the ability to both battle climate change and restore soils, biochar has plenty of benefits for backyard growers.

Biochar is charcoal made by burning woody materials, agricultural waste or any dried organic material like manures in a low-oxygen environment. Unlike charcoal, biochar is intended for combining with soil and has some properties that make it excel at this.

For your soils to get the most out of biochar, it should be ‘charged’, which means soaked in a nutrient-rich mix such as manures, urine, worm castings or compost. Left uncharged, it can bind nutrients and make them less available, at least in the short term. Even uncharged, biochar will eventually still improve the nutrient-holding capacity and exchange in soils.
