Optimum Temperatures

• Composting requires an optimal range of between 135 and 160 degrees F, according to the Washington State University website. This temperature range is essential for the destruction of pathogens and related organisms.
  
  

Measuring

• Composting temperatures can be measured to ensure the correct temperature range. Taking temperature readings in several locations within the pile over a period of days can help determine the overall composting temperature.
  
  

Heat Fluctuations

• Temperatures in composting piles can be indicators of the health and progress of the composting process, according to the Cornell University website. Drops in temperature result in the creation of an anaerobic state, which stalls composting; excess heat causes the death of the micro-organisms that turn the collected organic material into compost.
  
  

Excessive Heat

• If the composting temperature is too high, the micro-organisms that assist decomposition cannot maintain the process for extended periods. Aeration of organic material can help stabilize the temperature, which is why it is important to turn over your compost pile periodically..
  
  

Pathogens

• According to the University of California website, maintaining the proper composting temperatures kills pathogens and reduces the potential for disease transmission from spoiled material.
