Compost is produced when bacteria , yeast and fungi breakdown organic materials by aerobic (with air/oxygen) decomposition. Composting accelerates the natural biodegradation of organic materials, producing more stable forms of organic matter including humic substances. These are stable products which contain carbon and nitrogen as well as many other nutrients.
As compost decomposes in the soil it binds with the soil (acting like glue) to create a granular structure The bonds formed provide resistance to wind and water erosion. The more open structure gives better infiltration and plant root growth and increases the ability of the soil to retain added nutrients (cation exchange capacity.)
Quality compost can be the basis of very productive and valuable pasture and agricultural production when used in an integrated nutrient program.
