During our limited-time presale, you can sign up to purchase our biochar in advance at a discounted rate! Biochar is a soil improver that can be used with fertilizer to increase crop yields by up to 200%. In addition to output increases, biochar is a sustainable solution that improves the long-term quality of soil and sequesters carbon, making it one of the most environmentally-friendly nutrients. Further, it is an extremely long-lasting solution, as it needs to be reapplied to soil only once every ten years. Note: you will not be charged until our biochar is sent out for delivery!
