Mushroom Mulch
What is it?
Spent Mushroom Substrate (SMS) is a composted, growing medium that results from the mushroom growing process.
SMS is made from agricultural materials, such as wheat-straw dedded horse manure, hay, poultry manure, cottonseed meal, cocoa shells and gypsum. Mushroom production takes place in specialized, climate controlled rooms and lasts for approximately 70 days before new compost is required.
When new compost is needed, the SMS remaining from the old compost is steam pasteurized to reduce hygiene problems for the next mushroom crop and then removed from the growing rooms. SMS can be used for other agricultural crops and products since it is an ideal soil amendment with important nutrients.
No returns on natural stone products.
