Windrow or Other Composting

The aerobic (in the presence of oxygen from the air) biological process where biodegradable material (such as garden and kitchen waste) is converted into a stable friable material which, applied to land, improves both structure and enriches the nutrient content of soil. In some cases, this is referred to as a soil improver to distinguish it from peat and other compost products that are available to horticulturalists.
