It's composted until it turns into Humus. We use Agricultural crop residues such as wheat straw, old hay, and cotton gin trash (which is the leaves and burs after they are separated from the cotton). These sources of carbon break down easier and faster than wood products. In essence our product is much heavier than the competition's products. All bagged compost products are sized to stay in a weight range of 30-40 lbs per bag. Being humus, the nutrients are immediately plant available (the smaller the particle the more plant available it is). We also use a source of natural bacteria and fungi that we leach out into water and spray them into our composting process that aids in the hummification process. These bacteria and fungi remain in the compost and go to work in the garden when the compost is applied. Our organic compost in a bag is for the professional landscaper or the home gardener.
