Without wasting much time, let us dive right in.
What is Mushroom Compost?
Often time when you purchase mushroom compost from the store, it reads mushroom soil or feed. This makes a lot of people to believe that it consists mainly of mushroom. But this is not entirely true.
There are different types of mushroom compost and they are
Mushroom compost is often referred to as the mushroom substrate. This is the medium in which mushrooms are growing. Industrially, a mushroom substrate is made from a mix of manure, gypsum, and wheat straw. In most cases, chicken or horse manure is commonly used since it is readily available.
To produce mushroom substrate in large quantities, the manufacturer begins by soaking large bales of straw in water. Once the straw is soaked and spongy like, it is chopped into fine pieces by passing it through a chipper or using other methods.
The gypsum and manure are blended. This is to ensure they mix properly before the straw is then added into the mix. Once ready, the mixture of the gypsum, manure, and straw is then left on a hot compost pile to begin the composting process.
To ensure that the materials mix properly and compost together, the pile is watered and turned regularly. When done properly, this process can take as fast as 2 weeks.

This type of mushroom compost is low in nutrients compared to the substrate. This is because the spent mushroom is usually used as a recycled compost from the remains of mushroom farming.
Although the Nitrogen content in this mushroom compost is low, it can be used as a conditioner to improve the soil in your garden. Spent mushroom can be used to improve the soil conditions of your lawn. It can also be added to a raised bed or planting mix to improve water retention.
Will Mushroom Compost Burn Plants?
In most cases, when you add mushroom compost to your soil, you notice yellowish colorations on the leaves which is referred to as burning. The truth is that there are a lot of things you need to consider before adding mushroom compost to your plants’ soil.
You need to note the nutrients that are deficient in your soil. Mushroom compost is alkaline; this means that it will be deficient in some nutrients that your plants need.
You may need to perform a soil test to determine which nutrients your soil desperately needs. This makes it easy to determine whether you need a mushroom compost or you will be better off with a fertilizer.
Adding too much mushroom compost with a high salt content can cause your plant to burn. This is why you need to consider the soil test before adding compost or fertilizer to your garden.
Salt Content in Mushroom Compost
Mushroom compost contains a lot of salt. This is mostly due to the presence of high levels of sodium in the gypsum and manure. In a recent study, samples of mushroom compost were collected for analysis. And it was discovered that they contained low levels of sodium.
When the soil is high in sodium, it can cause problems with water retention by the plant root. It can also affect the structure of the soil, which is why you want to carry out a soil test before adding mushroom compost.
The salt content of mushroom compost depends on how the compost was manufactured. Most manufacturers mix their mushroom compost with nutrient-rich soil. This helps to balance out the deficient nitrogen and also reduce the salt content.
How to Use Mushroom Compost?
When applied to your soil properly, mushroom compost can provide nutrients for your soil, improve the water retention and drainage properties, and also work miracles for your soil texture.
