Abstract:

The large cubic capacity and invariable climate of the huge mushroom caves in Hungary makes continuous production possible even without using expensive air conditioning systems. To replace earlier low-yield production methods that involved too much hard manual labour in these caves, we have introduced a special intensive procedure.

By using a type of bag that utilizes floorspace ideally, and by introducing a second growing tier, the compost accomodation of the caves has been increased to three or four times the earlier figure per growing cycle. Due to a new shape and spatial arrangement of the bags, the increase of danger of compost overheating is far outweighed by the increase of compost weight made possible by the new method By using the newest hybrid strains and creating more suitable environmental conditions than before, the number of production cycles has been raised from three to five per year. Owing to a high technology compostation method and improvements in production technology, average yield per compost weight has increased by 20% despite shorter cycles. Taken together, the factors listed have resulted in a multiplication of output quantity.

At the same time, the introduction of relatively simple and inexpensive rack units of our own design and construction – that are moveable by fork-lift trucks – has made it possible to reduce the hard manual labour of transferring bags. By advanced casing time, i.e by performing casing just after spawning and prior to placing bags on rack units, another large amount of manual labour has been spared (the unusual procedure has turned out not to be inferior in terms of security).
