Biochar is a carbon-rich material produced by the thermal decomposition of organic matter (such as wood, manure, agricultural residues, and other types of biomass) in an environment with limited oxygen. When applied to soil directly, or in a mix with compost, biochar delivers long-lasting benefits to soil health and plant growth. The use of biochar can improve soil health by increasing nutrient retention and water filtration as well as enhancing beneficial soil microbes. Additionally, biochar can help to reduce compaction and increase drainage in soils. Biochar is also beneficial for soil health and fertility. This is because biochar can hold onto nutrients and moisture, making it available for plants to use.
