"Oyster Mushroom, Tree Oyster, Hiratake, Tamogitake" approx. 500 ml wood spawn colonized with mycelium, Growing conditions: Spawn run: 18,3 - 23,9 °C Primordia formation: 10 - 15,6 ° C Fruiting: 10 – 16 ° C Convenient substrate: Hardwood Mycorestoration use against: Presistent Organophosphates (In agriculture, the are used in fertilizers and as insecticides, and by the Military as nerve agents This substances are also component of flame retardants, softener, adhesives and for petroleum products as additive) Nitrate (In most cases of excess nitrate concentrations in ecological systems, the primary source is from agricultural or landscaped areas which have received excess nitrate fertilizer.) Dimethyl methyl phosphat (main use in chemical weapons – i.e. VX, Soman or Sarin; nerve agents, that disrupt the mechanism by which nerves transfer messages to organs. The disruption is caused by blocking acetylcholinesterase, an enzyme that normally relaxes the activity of acetylcholine, a neurotransmitter. Poisoning by a nerve agent leads to contraction of pupils, profuse salivation, convulsions, involuntary urination and defecation, and in most cases death by asphyxiation as control is lost over respiratory muscles). General procedure: Mushrooms use strong enymes to decompose primary structural components of wood (lignin and cellulose. The same enzymes can be used to absorb and neutralise heavy metals and toxins, and removing them permanently. Mycelium (spawn) of a convenient mushroom species is distributed over the contaminated area. Mix the spawn with fresh baic material (i.e. wood chips) and cover the source of toxication extensive. While the mushroom mycleium grows all over the contaminated soil, toxins are absorbed or decomposed. The mushoom will accumulate this toxins in the fruiting bodies. Therfor please dispose them after harvest. This is the way how you get your garden clear of toxins and heavy metal!
