Consultation: Is it necessary to add plaster and lime in edible mushroom cultivation materials?
Answer: Gypsum, also called calcium sulfate, is added in an amount of about 0.5% of the total amount of culture material. It can supplement the nutrients such as sulfur and calcium needed for the growth of edible fungi, and at the same time, it has the effect of stabilizing the pH, so that the pH of the culture material does not change greatly.
Lime, quicklime used for mushroom production is also called calcium oxide. The addition amount is about 2% of the total amount of the culture material, and it can also be used to adjust the pH of the culture material in addition to supplementing the calcium of the mycelium of the edible fungi. In addition, it also has the function of preventing the contamination of bacteria and buffering the organic acids produced during the metabolism of mycelium.
Lime must be added during the seasoning. If the plaster is available, it is advisable to add it.
