Abstract/Contents: | "By understanding soil fundamentals, composters and organics recyclers can better understand the role that organic amendments play in healthy and productive soils. If sands and silts are the "skeleton" of the soil body, and clays and organic matter are the "muscles," it is the biological organisms in soil that give it life and energy and are responsible for driving most of the chemical reactions and transformations that occur in soil. A healthy soil contains a very large number of different kinds of species representing every kingdom in the biological world. The species include animals, plant roots, fungi and bacteria. Diversity refers to the number of different types of organisms present in an area and abundance refers to the number of individual organisms. Both diversity and abundance are strongly influenced by soil characteristics and by climate, thus these values vary greatly from one soil to another and from one region to another." |
