For best results, you should till this biochar into fertiliser, compost or some other nutrient rich, ecologically friendly soil cover and till into the top 6 inches of your soil. 1lb of this biochar is sufficient for a 10 square foot area, so the bag will cover an area of 200 square feet.
Please make sure before you purchase you accurately measure the area of land you need the biochar for and calculate the correct number of bags needed, for a full coverage. This will ensure optimal benefit for your soil and land.
Once in your soil, your biochar is completely carbon negative.
