Black Compost is a blend of organic matter (leaves and yard waste) that has been decomposed and recycled to be used as an amendment. Modern, composting is a multi-step, closely monitored process with measured inputs of water, air, carbon-rich, and nitrogen-rich materials. The decomposition process is aided by grinding the plant matter, adding water and ensuring proper aeration by regularly turning the mixture. There is no manure or food scraps that have been added to this compost. This creates a much more consistent product with less inorganic materials in it.
