What is spent mushroom substrate?
Spent mushroom substrate (SMS) is the material left behind after you’ve harvested your mushrooms. It’s usually made of things like sawdust, straw, and other organic materials that were used as a growth substrate during cultivation. Although it’s called ‘spent’, it still contains plenty of organic compounds, nutrients, and raw materials that can be repurposed. And the best part? Finding new uses for it reduces waste and supports sustainable practices.
How to dispose of spent mushroom substrate
Spent mushroom substrate (SMS) is incredibly versatile and can benefit your garden, compost, or even large-scale agriculture. Here’s how to make the most of it:
Soil conditioner
If your garden needs a little TLC, spread SMS right onto your garden beds. It improves the soil’s structure and adds organic matter, making it perfect for flower beds or veggie patches that need a pick-me-up.
Composting
Got a compost bin? Toss your SMS in! It breaks down quickly and works wonders when mixed with kitchen scraps, leaves, or sawdust. The result? Rich, nutrient-packed compost your plants will love.
Agriculture
For those with access to manure (like chicken or pig), mixing it with SMS creates a supercharged compost. It’s a game-changer for soil health and crop yields, whether in a small garden or on a farm.
