According to Soil Building Systems Inc., Sawdust shouldn’t be used as a soil amendment as its decomposition is very slow and will rapidly deplete existing nitrogen sources that may be in the existing soil. It has small particle size, which leads to poor aeration in the soil. On complete decomposition, cotton burrs are a great and powerful supply of nutrients and nitrogen. They also break-up tight clay based soils, improving moisture retention in sandy soils, and encouraging mycorrhizal interaction within root systems. Manure can be a great source of nitrogen and nutrients, if fully composted. But, its over-use can contribute to extreme levels of phosphorus and potassium, which can be harmful to the environment. Any consistently textured mulch should be satisfactory and will provide an adequate cushion for playgrounds.
