Using compost to generate heat within a greenhouse can be a very effectie way to provide supplemental heat for plants. As compost decomposes, it releases heat, a process known as microbial respiration. To harness this heat, you can create compost piles or bins within or near the greenhouse, where the heat generated will raise the ambient temperature.
To maximize the heat output, build large, well-aerated compost piles with a mix of nitrogen-rich materials like grass clippings and carbon-rich materials like straw or leaves. Turning the compost regularly helps maintain heat production by ensuring proper airflow. Positioning the compost near plants or using it as a floor covering can help warm the root zone, which is especially beneficial for sensitive plants during colder months.
