Mushroom compost is a by-product of mushroom farming. It is made from the spent mushroom substrate used in commercial production. The substrate consists of organic materials, such as straw, hay, poultry or horse manure, and crop residues. Mushroom compost is a nutrient-rich soil amendment that can improve soil structure, water retention, and overall plant growth. It has a pH level of around 6.6, which is ideal for most plants. Mushroom compost can be used as a mulch and soil conditioner, and can also be worked into the soil to improve its structure and enhance microbial activity. While it offers many benefits, mushroom compost has high salt levels, which may negatively affect plant growth, so it is important to test the salt content before use.

What You'll Learn
Mushroom compost is a by-product of mushroom farming
The process of making mushroom compost involves blending and pasteurizing various organic materials to create a nutrient-rich environment for mushrooms to grow. The substrate becomes enriched with nutrients and beneficial microorganisms during the mushroom-growing process as the fungi break down the organic materials. Once the mushrooms are harvested, the remaining compost can be repurposed as a soil amendment for gardening.
Mushroom compost is a versatile addition to any garden, offering benefits for many plants. It can be used as a mulch, soil conditioner, or top dressing to improve soil structure, increase nutrient availability, and enhance microbial activity. It is important to note that mushroom compost has high salt levels, which may negatively affect plant growth, so it should be used with caution and tested before use.
Overall, mushroom compost is a valuable resource for gardeners as it provides a sustainable option for improving garden soil while also supporting the circular economy by reducing waste in the mushroom industry. By choosing to use mushroom compost, gardeners can benefit their gardens and contribute to a more sustainable future.

It is a nutrient-rich soil amendment
Mushroom compost is a nutrient-rich soil amendment that is made from the spent mushroom substrate used in commercial mushroom production. The substrate consists of organic materials, such as straw, hay, poultry or horse manure, corn cobs, and other agricultural byproducts. These materials are combined and pasteurized to eliminate weed seeds and harmful pathogens, creating an ideal mushroom-growing medium.
The process of making mushroom compost involves composting the substrate for about 30 days at 160 degrees Fahrenheit. This kills any weed seeds, pests, or disease pathogens that may be present. Once the mushrooms have been harvested, the remaining substrate, or "spent mushroom compost," is removed and sold as fertiliser.
Mushroom compost is a valuable resource for gardeners as it contains a rich blend of nutrients, including nitrogen, phosphate (phosphorus), potash (potassium), trace minerals, and organic matter. These nutrients can improve soil structure, increase water retention, and promote overall plant growth. It is important to note that mushroom compost has lower nitrogen levels compared to other types of compost, as this nutrient is depleted by the mushrooms during their growth.
Mushroom compost can be used as a soil amendment for lawns, gardens, and container plants. When using mushroom compost, it is recommended to mix it with garden soil prior to planting. It can be spread on the surface of the soil and then incorporated into the existing soil below. For container plants, a ratio of one part mushroom compost to three parts garden soil is suggested.
While mushroom compost offers many benefits, it is important to be cautious of its high soluble salt levels, which can negatively affect plant growth. To temper the alkaline levels, gardeners can consider using a diluting agent like aglime. Additionally, as with any compost, it is important to source mushroom compost from a reputable supplier to minimise the risk of introducing weeds to your garden.

It is made from spent mushroom substrate
Mushroom compost is a by-product of mushroom farming. It is made from spent mushroom substrate, which is the residual growing medium used to cultivate mushrooms. The substrate typically consists of organic materials such as straw, hay, corn cobs, poultry or horse manure, and other agricultural by-products. These materials are combined and pasteurized to create an ideal environment for mushrooms to grow and to kill weed seeds and harmful pathogens.
The process of making mushroom compost involves composting the substrate for about 30 days at 160 degrees Fahrenheit. This composting process kills weed seeds, pests, and disease pathogens. After composting, the substrate is ready to be used as a growing medium for mushrooms. Once the mushrooms have been harvested, the remaining substrate is no longer suitable for mushroom production, but it has become a valuable resource for gardeners.
The spent mushroom substrate is sold in bags or bulk, often labelled as SMC (Spent Mushroom Compost) or SMS (Spent Mushroom Substrate). This substrate has become a popular soil amendment for gardeners due to its rich blend of nutrients, including nitrogen, phosphorus, potassium, trace minerals, and organic matter. These nutrients can improve soil structure, increase water retention, and enhance overall plant growth.
When used properly, mushroom compost can act as a plant fertilizer and soil amendment, providing a readily available source of organic material for the garden. It can be blended into the soil to improve its structure and aeration, increase its moisture-retaining and drainage capabilities, and provide essential nutrients for plant growth. However, it is important to note that mushroom compost should not be used as a replacement for standard compost, as it can hold too much water and become waterlogged, potentially causing problems for plants.
To get the best results with mushroom compost, it is recommended to mix it with garden soil prior to planting. For container plants, a ratio of one part mushroom compost to three parts garden soil is suggested. Additionally, mushroom compost can be used as a mulch product, spread as a layer on top of the soil to suppress weeds and improve the soil over time.

It is high in organic matter
Mushroom compost is a by-product of mushroom farming. It is made from the spent mushroom substrate used in commercial production. The substrate typically consists of organic materials, such as straw, hay, corn cobs, poultry or horse manure, and other agricultural byproducts. These materials are combined and pasteurized to eliminate weed seeds and harmful pathogens, creating an ideal mushroom-growing medium.
Mushroom compost is high in organic matter, which enhances all types of soils, from heavy clay to light, free-draining sand. Organic matter improves the structure and aeration of the soil, creating greater moisture retention and drainage capability. This helps to amend clay-like soils over time and can be an effective mulch product when fresh, as weed seeds find it more difficult to take root in.
The organic matter in mushroom compost also provides the nutrients that plants need to grow well. The three main plant nutrients found in the soil are nitrogen, phosphorus, and potassium, while magnesium, calcium, and sulphur are also important. These nutrients work together to help plants grow strongly and produce flowers and fruit.
Mushroom compost is a slow-release organic plant fertilizer. It is a viable and useful by-product of mushroom farming. The growth medium of mushrooms is removed after the mushrooms are harvested, and the leftover compost is disposed of and sold as fertilizer.

It has a pH of 6.5-7
Mushroom compost is a by-product of mushroom farming. It is a mixture of agricultural materials, such as straw, hay, corn cobs, and poultry or horse manure. This mixture is composted for about 30 days at 160 degrees Fahrenheit to kill weed seeds, pests, and disease pathogens. The pH level of mushroom compost is typically around 6.6, which falls within the ideal pH range for most crops of 6.0 to 7.0.
A pH level of 6.5-7 is considered slightly alkaline. This alkalinity can be beneficial for certain types of plants. For example, a higher pH can help defend against club root in brassicas (vegetables in the cabbage family) and blossom end rot in tomatoes.
The pH level of mushroom compost is also important for its use as a mulch product. Fresh mushroom compost can be effective at suppressing weed growth due to its pH level and alkaline nature. As it breaks down, mushroom compost can be worked into the soil to continue improving soil structure and water retention.
When using mushroom compost, it is important to consider its high soluble salt content. The salt levels in mushroom compost can negatively affect plant growth, particularly for salt-sensitive plants. To mitigate this, the compost can be diluted with other organic materials or used as a top dressing rather than incorporating it directly into the soil.
Overall, mushroom compost is a valuable resource for gardeners due to its nutrient content, ability to improve soil structure, and suitability for a wide range of plants. Its pH level of 6.5-7 is well-suited for most crops and can provide benefits for both soil and plants.
