Biochar is the output of burning biomass (plants and woods). If you burn wood and timber, it is called charcoal. Biochar/charcoal are used for soil treatment. The production’s process of biochar is often done by 400-500°C tempreture and without Oxygen. The process is called pyrolysis. Pyrolysis happens therethroug CO2 emissions neutral. Biochar also seems to be the main ingredient of the famous terra preta, the betterSoil of the Amazon. Adding biochar to your compost and to your soil makes your soil better. Soils with biochar are able to remove greenhouse gas emissions from the atmosphere and put it back where it belongs to, to the soil! At the same time biochar boosts the resilience and fertility of your soil and crops greatly.
Why is biochar important?
Biochar has a porous structure, which increases the inner surface of the soil. Thus it acts as a house and factory for microorganisms, which work on humus build-up. Furthermore, biochar promotes the fertility of the soil by increasing the binding of nutrients and preventing water losses. Imagine a super-sponge storing nutrients and water, giving house to a productive army of microorganisms, while potentially being constructed from atmospheric greenhouse gases, among others CO2. That is biochar for you!
