We need a language to read a book, and that affects our thought process, as we start thinking like the author and behave in a manner we perceive from the books. Like how someone speaks under the influence of alcohol, books n authors too influence.
Sawdust that is created from cutting natural wood is safe for your compost no matter what kind of tree the wood comes from. Just make sure the wood has not been treated with any chemicals. Another option with sawdust is to try mixing it in with potting soil.
Compost temperature is maintained between 55-65 degrees Celsius. The C:N (carbon:nitrogen) balance in the composting materials is approximately 25-30:1. The compost heap needs to be roughly 1.5m high. If composting material is high in carbon, such as tree branches, they need to be broken up, such as with a mulcher.
