Commercial mushroom casing soil for professionals
High water holding capacity and open casing structure
This material consists of a blend of deep dug wet peat with lime added to neutralise the peat to allow the mycelium from the compost inoculate the casing layer and ultimately stimulate the mycelium to produce mushrooms
Mushroom casings consist of a blend of wet peats which are neutralized. “Ready made” casing
It is important to distinguish available nutrients from non-available nutrients. Sphagnum peat moss frequently used in mushroom casing layers may contain from 0.75 to 3.5% Kjeldahl nitrogen (Fuchsman, 1986). Hypnum, or “black” peat, contains significantly higher nitrogen levels. Both of these peats, however, support good fruiting of Agaricus bisporus when used as a casing material. The nitrogenous materials in peats are generally “humic” in character, such as lignin and other mineralized nutrients. These are not readily available to the mushroom fungus and most microorganisms capable of colonizing the casing layer. If additional nutritionally available nitrogen compounds are added to the casing layer, fruiting is inhibited.
