Biochar

Biochar replenishes and retains soil nutrients so crops will be more nutrient-dense. It improves cation exchange capacity for greater mineral delivery to plant roots and increases microbial populations, including increased reproduction and higher retention of microorganisms. Biochar produces healthy tilth and structure (humus), reducing compaction so soil can breathe. It neutralizes and maintains pH of soil and toxins in the soil. Biochar increases the water holding capacity of the soil and improves germination of seedlings. It improves resistance to infestation by fungus, nematodes, and insects. It also provides a rich source of carbon to build hummus/organic matter and increase productivity.
