Heterooxopolyaniont cluster of general formula ([(P)a(Si)b (B)c (W)p (Mo)q (V)rO40] x-, where phosphorus is in oxidation state +5, silicon is in the +4 oxidation state, boron in the +3 oxidation state, the indices a, b and c are numbers from 0 to 1 and the sum a + b + c = 1, the tungsten is in an oxidation state +6, molybdenum is in oxidation state +6, vanadium is in oxidation state +5, the indices p, q, r are numbers from 0 to 12, the sum p + q + r = 12, x = 80-5-4b-3c-6p-6q-5r, eventually in compex with humic acid (Pazdera P., Pazderova J., Kovar M., Havel J.: Formulation for suppressing effect of stressors to plants and for increasing condition of plants, CZ20110450 (A3), 2013-02-06. ).

Thanks for this answer Dr. Pazdera, it introduced me to new concepts.  Do you think this kind of compound would be present after an anaerobic fermentation process of ruminant manure? 

Dear Carlos,

It can not be ruled out. But the concentration levels will be very low, of the order below ppb / ppM because low concentration of Mo, W and V in the environment (soil). Our product is applied at 1-10 ppm on the green leaf area of plant. 

Diluted application solution should be applied for highest effectivity by spraying on (leastwise partly) green plant face and also unfolding floral and leaf buds, three to five times during vegetation year or vegetation period. Its application reduces depletion of pesticides and fertilizers.

We have the very good application results with this new  antistressor for some cultural green plants such as corn, vegetables (cucumbers, tomatoes, cauliflowers), fruit trees (peaches) and shrubs (gooseberry, fig tree), roses and woody plants (spruce tree). Further research will be realized in Horizon 2020 under participation some universities form Italy, Spain, Sweden, Greece, Czech .....
