Microorganisms are essential in the composting process. These microscopic organisms are the tiny guys and gals that play a major role in decomposition. Compost microorganisms break down raw, organic compost matter and convert it into mineral-rich garden soil. There are four types of microorganisms that aid in the process.
In the composting process, micro-organisms produce carbon dioxide, heat, water, and humus…. finished compost that is ready for use by your plants.
Would you like to get technical on these decomposition helpers? Sure you do! These are the Types of microorganisms that help to decompose organic materials:
Fungi – including molds and yeasts
Actinomycetes – bacteria similar to fungi
Protozoa – single-celled, feeds on organic matter
Rotifers – feeds on organic matter, bacteria and fungi
Mesophilic, warm-up period: Aerobic bacteria are at work. Temperatures are 70-90 degrees F. Aerobic microorganisms, which require oxygen, are working on the compost.
Thermophilic, high heat period: Temperatures reach 100 to 170 degrees F. The microorganisms dominant in this stage, are anaerobic. This stage usually lasts 3-4 days. With high heat, weed seeds and other seeds are killed.
Cooldown period: Temperatures cool off and aerobic micro-organisms take over once more.
Micro-organisms are present in your garden soil, on plants, and in any compost pile. To kick-start the decomposition process, you don’t need compost activators. Just add a shovelful of dirt, or finished compost from your last batch, to the raw materials.
