Characterisation of different substrates for possible use as casing in mushroom cultivation

In this study we describe the principal physical, chemical and biological characteristics of different materials and mixtures for possible use as casing in mushroom cultivation. Besides the base of mineral soil used for the preparation of the mixtures, we have analysed different substrates for use as structural correctors and as water holding agents. Of possible alternative materials to the traditionally used peat, coconut fibre is confirmed as the best because of its high porosity and water holding capacity. As regards the mixtures, their characteristics are in accordance with the components included and conditioned by the characteristics of the soil used. Subsequent evaluation of these mixtures for mushroom cultivation would be of great interest.
