Biochar embodies a critical aspect of Indigenous Traditional Ecological Knowledge that is increasingly recognized in contemporary discourse, particularly as corporations begin to commercialize this process. The methodology for producing black earth has been established for over 5,000 years. Indigenous peoples worldwide, including numerous tribal nations, have consistently refined and utilized these practices to support agricultural systems and create black earth. This exemplifies the transfer of practical knowledge through ancient trade networks on a global scale. Indigenous farmers and gardeners continue to implement techniques passed down from their ancestors, utilizing traditional, homemade methods. Communities actively employ these practices to improve soil quality. Presently, advanced techniques are integrated by these communities to enhance the soil's capacity to retain moisture and nutrients, ultimately benefiting plant growth and optimizing crop yields.
