If you are going to compost dead animals on your farm, you need a good thermometer, says Brent Auvermann, associate professor of biological and agricultural engineering at Texas A&M University.
Just as a doctor takes your temperature to determine your health, you use a thermometer to judge the health of your compost pile.
Auvermann recommends purchasing a 4-foot long-stemmed thermometer for about $150. “It’s the best investment you can make to help manage your compost pile,” he says.
