Mushroom growers offer a valuable service to livestock, poultry, and cash crop farmers by transforming their agricultural by-products into mushroom substrate - a nutrient-rich growing medium for mushrooms. Because the needs of mushrooms are green plants are very different, after the mushroom growing cycle is complete, the farmer is left with spent mushroom substrate - a soil-like material that is full of nutrients beneficial for other crops. Spent mushroom substrate is then recycled and offered to cash crop farmers for their fields or is sold by nurseries as a soil conditioner for the average gardener. It’s a beautiful life cycle if you ask us!
