Mushroom casing soil

BVB Substrates supplies mushroom growers with professional casing soil, which is delivered worldwide. We offer casing soil in different densities and moisture levels, and we take hygiene matters very seriously.

Mushroom casing soil

Our casing soil is made of high-quality European deep dug peatcombined with frozen black and white peat. We use sugar beet lime to reach the right pH level. BVB Substrates can also produce different types of casing soil that are tailored to the needs of each specific growing type, including organic farming and different mushroom species. We make specific mixtures for growers that hand pick their mushrooms, and casing soils for growers that harvest their mushrooms mechanically.


We offer casing soils with different moisture levels, ranging from 68-80%. These mixtures are tailored to fit our customer’s needs. We can also adjust the mixtures to increase their process ability.

Kekkilä-BVB has developed its own assessment method for casing soils. We also have our own spray tables to ensure a stable product and constant quality. We check the water uptake capacity, pH level and adhesive strength. In particular, in the cultivation of mushrooms, it’s tremendously important to constantly check the quality of the casing soil.

How is our casing soil produced?

In the cultivation of mushrooms, hygiene is key. This is also an important part of our soil production processes. It’s why all of the trucks carrying our casing soil are thoroughly cleaned in our own car wash after each delivery. We also emphasize the importance of hygiene during the pre-wetting phase.
