The key to growing bigger, more productive, more nutrient-dense plants starts at ground level. Biochar, which is slow-roasted organic matter inoculated with compost, creates the perfect habitat for soil-enriching microorganisms. In Gardening with Biochar, longtime garden writer Jeff Cox explains what biochar is and provides detailed instructions for how it can be made from wood or other kinds of plant material, along with specific guidelines for using it to enrich soil, prevent erosion, and enhance plant growth. If you want to create long-term benefits for your garden through better soil, this is the book you want to pick up.
