Biochar is a charcoal that is made from organic materials, and should not be confused with the charcoal that is used on the grill. It's made by burning organic material such as wood, bone, and manure at a very low temperature. It will help the soil retain nutrients as well as water. Simply sprinkle some on top of your soil and work within 4 inches of the top. Like ashes though, biochar can raise the pH level of your soil, so be sure to check the levels consistently!
