Adding Microbes Turns Spent Mushroom Substrate Into Better Compost Faster
What they found
A microbial inoculum sped up composting of spent mushroom substrate and chicken manure, yielding compost richer in nitrogen, phosphorus, and potassium with lower methane emissions.

Mushroom Substrate Waste? Fungi Can Break Down That, Too
Mushroom Substrate Waste? Fungi Can Break Down That, Too
Not-so-fun fact As much as we love our delicious mushrooms … spent mushroom substrate (SMS) is a major contributor to the 1 billion tons of agricultural waste created worldwide every year. China, the world’s largest mushroom producer, creates about 50 million tons of SMS. Fortunately, SMS can be a valuable compost resource, turning waste from one harvest into potential nutrition for another. A recent study shows that microbial inoculums (mixtures of beneficial bacteria and fungi) can optimize the composting process. - Food webs A healthy compost pile is a diverse “food web” of insects, bugs, slugs, earthworms, and microorganisms like bacteria and fungi. Surprisingly, these microorganisms are responsible for the bulk of the organic matter decomposition in your compost! - Key differences Bacteria take up more nitrogen as they grow, while fungi need more carbon — and the balance between these two microorganisms contributes to nutritious compost. Soils with a higher fungi-to-bacteria ratio are considered to be more fertile. - Golden ratios Researchers have experimented with these ratios to speed up the composting process. Using a mixture of SMS and chicken manure, three treatment groups were established: one with a microbial inoculum, another with a commercial inoculum, and a control group that received no inoculum. - Better ingredients, better compost The microbial inoculum accelerated the breakdown of organic matter and produced superior-quality compost. This compost had more nitrogen, phosphorus, and potassium — all essential nutrients for plant growth. - Faster & cleaner Using microbial inoculum also decreased greenhouse gas emissions like methane during composting. - Composting at home Optimized composting could revolutionize how we recycle commercial agriculture waste. But for those who enjoy composting at home, understanding the role of fungi and beneficial bacteria in compost can help create a more sustainable experience for us and the environment. Some organic gardening shops sell microbial inoculants that claim to accelerate composting. Of course, be sure to research any products you wish to introduce to your garden compost!
