Luster Leaf Dial Compost Thermometer
Temperature plays an important role in the composting process. Decomposition occurs most rapidly between 110 and 160 degrees Farenheit. Within two weeks a properly made compost pile will reach these temperatures. At this time you will notice your pile settling which is a good sign that the pile is working properly. Now you must decide how you want to compost. Do you want to add to your pile or just let it continue as is? If you want to add to your pile you can do so throughout the growing season and into the winter months. As you add fresh material you will need to turn and water your pile more often. Monitoring the temperature and turning whenever the piles temperature dips below 110 degrees Farenheit keeps your pile active at its highest level and you will have the fastest breakdown. This means turning the pile more often. This can be weekly and it does involve some work. There are different types of aerobic bacteria that work in composting piles. Their populations will vary according to the pile temperature. Psychrophilic bacteria work in the lowest temperature range. They are most active at 55 degrees Farenheit and will work in the pile if the initial pile temperature is less than 70 degrees Farenheit. They give off a small amount of heat in comparison to other types of bacteria. The heat they produce is enough however to help build the pile temperature to the point where another set of bacteria mesophilic bacteria start to take over. Mesophilic bacteria rapidly decompose organic matter producing acids carbon dioxide and heat. Their working temperature range is generally between 70 and 100 degrees Farenheit. When the pile temperature rises above 100 degrees Farenheit the mesophilic bacteria begin to die off or move to the outer part of the heap. They are replaced by heat-loving thermophilic bacteria. Thermophilic bacteria thrive at temperatures ranging from 113 to 160 degrees Farenheit. Thermophilic bacteria continue the decomposition process raising the pile temperature to 130 to 160 degrees Farenheit where it usually stabilizes. Unless a pile is constantly fed new materials and turned at strategic times the high temperatures typically last no more than three to five days. Thermophilic bacteria use up too much of the degradable materials to sustain their population for any length of time. As the thermophilic bacteria decline and the temperature of the pile gradually cools off the mesophilic bacteria again become dominant. The mesophilic bacteria consume remaining organic material with the help of other organisms.
