Abstract: The invention consists of a granulated fertilizer which contains iron (11 to 13%), zinc (3 to 9%), manganese (0.1 to 2.5%), copper (0.5 to 0.7%), in the form of sulphates, also ammonium molybdate (0 to 0.1%) and a Caolinite, Ilite or Montmorillonite clay (45 to 57%), or a mixture of them in any proportion. All the percentages by weight are based on the total weight of the fertilizer. The product is 100% soluble, the high cationic exchange capacity which clays have allows the micronutrients to be adsorbed by the clay and prevent its leaching or reacting, making its assimilation by the plant more efficient and better. The use of sulphates in the soil, in the presence of water provoks an acidification of the soil which allows a better assimilation of the micronutrients in alkaline soils.
