What is Mushroom Compost?Often referred to as Spent Mushroom Substrate (SMS), Mushroom Compost is the growing medium that results from the mushroom growing process. Mushroom Compost is made from agricultural materials, such as hay, straw, straw horse bedding, poultry litter, cottonseed meal, cocoa shells and gypsum. Sphagnum peat moss adds to the organic nature of the substrate, providing a consistent, formulated and homogeneous product.
PDA Accepted FertilizerAfter mushrooms are harvested, the Mushroom Compost is steam treated prior to removal to eliminate any pest, pathogens and weed seeds resulting in a Pennsylvania Department of Agriculture accepted fertilizer product.
Mushroom Compost should always be used in accordance with good farming practices and in conjunction with a Nutrient Management or Soil Conservation Plan. Your local Conservation District can answer any questions about the proper use of Mushroom Compost as they work with you in implementing Best Management Practices. Mushroom Farms Recycle
