A High-Value Soil Supplement
Mushroom cultivation is not only a rewarding hobby but also offers an excellent opportunity for sustainability through repurposing spent substrate. As you delve into the world of mushrooms, you quickly learn that the substrate, the material on which the mushrooms grow, becomes rich in nutrients once the mushrooms have completed their growth cycle. This used or spent substrate is a treasure trove for gardeners, acting as a high-value soil supplement for flowers and vegetable farming. Here’s how you can turn your mushroom cultivation by-product into a beneficial product for green thumb gardeners.
Understanding the Value of Spent Mushroom Substrate (SMS)
Spent Mushroom Substrate, often abbreviated as SMS, is the leftover material after a mushroom crop has been harvested. Typically consisting of organic materials like straw, sawdust, or manure, SMS is enriched with mycelium and leftover nutrients. This makes it an excellent amendment for garden soil, offering multiple benefits such as improved soil structure, enhanced water retention, and a slow release of nutrients.
Some of the best flower growers love to use SMS to get the best results for their roses or other prize-winning flowers.
