Title: Water hardness and CaCl₂ in Dutch mushroom growing systems: Effect on yield and quality
Authors: B. Desrumaux, A. Calus and P. Sedeyn

Abstract:

The mushroom yield is not influenced by the use of hard, middle-hard or relatively soft irrigation water. Yields tend to be smaller as the calcium chloride dose added to the irrigation water is increased from 0 to 0.4%. The mushroom color at picking is not influenced by the type of water or by the administering of calcium chloride. During conservation, it has been found that CaCl₂ has a positive influence on the mushroom color. The color improvement is based on a slowing down of the yellowing and a brighter color. The effect is only noticeable in the 2nd flush after long-lasting conservation (6 days), in older flushes somewhat earlier (4 days). The mushroom dry matter level is slightly positively influenced by the administering of calcium chloride. Perchance this directly results from the increase of the casing soil EC. The mushroom calcium level increases as a result of the calcium chloride administering.
