There is no known solution that can be used for liquid fertilizer. A powder mixture obtained by mixing the above various metal complex compounds is commercially available, but by dissolving this in water,
Furthermore, ammonium chloride, ammonium sulfate, ammonium nitrate, potassium nitrate, etc. as nitrogen components, sodium phosphate, potassium phosphate, etc. as phosphorus components are added to form an aqueous solution, which is appropriately diluted and used as a liquid fertilizer for hydroponic cultivation, etc. Even in the above aqueous solution, crystals are precipitated during storage.
There is no problem when the prepared product is consumed all at once, but it is not preferable when the product is taken out little by little and used by diluting it, because the precipitation of crystals changes the component balance of the solution.

All of these metals form complex compounds with polyaminopolycarboxylic acids such as ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), hydroxyethylethylenediaminetriacetic acid (HEDTA) and nitrilotriacetic acid (NTA). is there. This complex compound may be separately prepared for each metal and taken out as crystals, or the polyaminocarboxylic acid may be dissolved in water using an alkali such as caustic soda or caustic potash, and then salts of various metals may be added thereto. Can also be built.
When the former method is used, the water of crystallization is contained in the crystals, so it is advisable to determine the blending amount in consideration of the water of crystallization in order to balance the content of each metal as a whole.
