Mushroom compost is the sustainable process of producing compost for use in gardening and farming from waste materials generated by the mushroom growing industry. This compost is created by composting spent mushroom substrates, which are the materials used to grow the mushrooms, such as straw, horse manure and poultry litter.
The composting process is typically carried out in large piles or windrows and can take several months. The end result is a nutrient-rich compost that provides an excellent source of organic matter and essential plant nutrients.
Mushroom substrate can be used to improve soil fertility and structure in a variety of crops, including vegetables, fruits, and flowers.
