Every year the same natural cycle occurs; leaves, twigs and trees fall to earth, decompose and become food for new plants. Naturally occurring micro-organisms, bugs and worms, together with oxygen and moisture do all the work. In the process heat is produced. Some very valuable micro-organisms work at temperatures as high as 65C (150F)! This is \'?hot\'? composting, oxygen in the air is critical to the process.
