What is mushroom compost?
Mushroom compost is a type of slow-release, organic plant fertiliser. It is a viable and useful by-product of mushroom farming. The compost is made by using organic materials such as hay, straw, corn cobs and hulls, and poultry or horse manure. These products are formed into a rich organic media.
The mushroom growing process varies slightly between individual growers, this leads to mushroom compost recipes differing to suit the needs of each grower. For instance, additional materials like gypsum, peat moss, lime, soybean meal, and various other organic items may be added to the compost as well. These products are formed into a rich organic compost that serves as the nutrient source for mushrooms.
How is mushroom compost made?
To start with the mushroom compost is sterilised and inoculated with mushroom spawn. Once the mushroom spawn are mixed into the compost, it is steam pasteurised to kill weed seeds and any other unsafe agents. Mushroom composting takes about three to four weeks to process, during which it is monitored closely to maintain adequate temperatures for optimum production. After the process is complete, the leftover compost is disposed of and sold as fertiliser, up to 2 crops of mushrooms are taken from the compost before being released to the landscape market.
Why use mushroom compost?
Mushroom compost is excellent for soil modification as it can radically enhance plant growth, even in the deprived type of soils. This is due to the fact that most of the amended compost serves effectively to improve the clay soil structure, increase soil fertility and lessen the chances of surface crusting as well as compaction. It can also help to improve drainage and ensure that the most natural nutrients are provided to plants which automatically minimizes the need to use fertiliser. Overall, this form of compost is highly beneficial to the soil quality.
How to use mushroom compost?
As a fertiliser and soil amendment, mushroom compost supports plant growth in a variety of applications such as herbaceous beds, shrubs, vegetables and landscaping.

Use 5-6 inches (13-16 cm) forked well into the soil to improve the condition of the soil, reducing heaviness and adding nutrients.
