Why A Compost Thermometer Is A MustA compost thermometer is one of the most essential tools you need to create a successful compost pile. After all, the temperature of the pile is what can make or break a good decomposing compost , and having the right balance of nitrogen and carbon to heat the scraps to the correct degree is key. Luckily, a compost thermometer, which is available at most home and gardening stores as well as online, will help you to determine the exact right heat balance you should maintain. Goldilocks Factor - Not Too Hot Or Too ColdIf a compost pile is too hot, the microorganisms needed to break down the pile will die off, and the rate of decomposition drops drastically. If your pile's temperature is too low, the microbes needed to kill pathogens and weed seeds will reduce greatly, producing the same failed effect. Most thermometers will read up to 200 degrees Fahrenheit, and have a 20” stem to reach the center of your pile. That is exactly what you'll need.When picking out a thermometer, make sure you find one that is easy to read and won't fog up on you. Stainless steels models that have been hermetically sealed are usually the best for this. After all, you will be inserting the thermometer into a steamy, contained area, and you want to be sure to get the most accurate reading possible without having to wait for the glass to defog. Once you have created your compost pile, it will begin to heat up, and will reach its peak temperature within about a week. At its hottest, the temperature will range between 120 and 150 degrees Fahrenheit (or 50 to 65 degrees Celsius). That’s perfect for breaking down a compost pile, but way too hot for gnomes. We can walk through solid earth , but only cool earth. Your pile should retain this amount of heat for about three days before slowly starting to cool off. The Thermometer Will Tell You When To Turn ItWhen the pile has cooled, turn the compost by either cranking the tumbling bin or stoking and flipping it with a hoe or shovel. Break up any clumps and move the mass to the center and away from the sides. If the compost is too dry, simply add a small amount of water until it is damp throughout.In another week, the temperature should peak again, and the same process should be followed. If you have a compost tumbler , your compost should be finished by the third week. It's important to make sure your temperature is consistent, and that your compost has reached its peak on more than one occasion. Record your data and temperatures in a book for future composting efforts, and put your compost to good use!
