Have you ever heard of biochar?
For most home gardeners, this term is probably brand new. In short, biochar is a charcoal compound that is added to soil to make it more fertile, and It has a long and complicated history of use in indigenous agriculture throughout West Africa and the Amazon rainforest, with incredible results that have been observed even to this day. This ancient method of agriculture can simultaneously increase yield and remove carbon dioxide from the atmosphere.
But what does this have to do with your garden? You may not run a high-yielding farm or attempt to sequester carbon. But biochar has many benefits for the soil in your yard or garden and can significantly increase its fertility. If your house is built on infertile land, the growth of your crops will be disappointing, but biochar can help restore poor soil and increase harvest and yield in your vegetable garden.
