Abstract
Water-soluble gelated micronutrient fertilizers containing 55 to 89% by weight of water soluble compounds of micronutrients of which 25 to 100 mol % of the cations are present in complexed form, 2 to 7% by weight of ammonium nitrogen as macronutrient, 2 to 18% by weight of polyglycol ether having at least 9 ethylene oxide (EO) units and/or water-soluble polyglycol ether derivatives having at least 8 EO units in the molecule and 7 to 20% by weight of water, process for their manufacture and their use for plant fertilization.
