This is 0.06 percent of 2,000,000 lbs. of soil. The above calculations show that it is not possible to increase soil organic matter at an annual rate of 1 percent.

To start the pile, create a base layer on bare soil with six to 12 inches of wood chips or chopped branches, then add alternating six-inch layers of damp green materials such as grass clippings ...
