Bison Soil Organic Biochar can be applied to plant beds, either when they are first planted or biochar can be worked into
the soil around each existing plant. Adding 2-5% (w/w) requires approximately 435 to 1000 cubic feet, respectively, of
Bison Soil Organic Biochar applied to approximately 1⁄4 acre (10,000 ft2) at 6 inches deep. This is equivalent to approxi-
mately 8100 to 20,300 lbs of Bison Soil Organic Biochar.
