Spent casing, Sphagnum moss, grass fibers, and green compost as peat alternatives in casing soils for Agaricus bisporus cultivation

Researchers tested alternative materials to replace peat in the soil layer used for growing button mushrooms. They found that moss and compost could replace up to 75% of peat without reducing mushroom yields, though grass-based materials were less effective. The study shows it is possible to move toward more sustainable mushroom farming while maintaining productivity and controlling plant diseases.
