I first heard about biochar from a gentle and unassuming older lady who was making biochar at home in her kiln. She explained the role that biochar could play in both the fight against climate change and the improvement of soil quality, before gifting me a small bag of it to try out in my own small vegetable garden. I decided to carry out some citizens science in my back yard and put biochar to the test. I planted 5 squash plants and added biochar to the soil for two of the five. To be frank, I didn’t really know what to expect but I will happily test anything that will organically allow me to fight climate change and grow better vegetables at the same time.
