Mushroom Compost is often referred at Spent Mushroom Substrate (SMS). Growing medium that results from the mushroom growing process. Mushroom Compost is made from agricultural materials, such as hay, straw, poultry manure, horse manure, stover, cobs, hulls, cocoa shells and gypsum. Sphagnum peat moss adds to the organic nature of the substrate, providing a consistent, formulated and homogeneous product.
Mushroom Compost is initially used in food production and therefore highly regulated and formulated. Because of this standardized formulation it is the ideal soil amendment for your yard, garden, farm and reclamation applications. Benefits you will recognize include: 1. Adds organic matter to soils. 2. Builds up the soil flora. 3. Improves water retention. 4. Relieves compaction problems. 5. Reduces the need for fertilizer.
