The invention relates to a granulated fertiliser containing 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, as well as ammonium molybdate (0 to 0.1%) and a kaolinite, illite or montmorillonite clay (45 to 57%), or a mixture of same in any ratio. All of the aforementioned weight percentages are based on the total weight of the fertiliser. The product is 100 % soluble. Moreover, the high cationic exchange capacity of the clays ensures that the micronutrients are absorbed by the clay and prevents the lixiviation or reaction of said micronutrients, thereby improving the assimilation of the micronutrients in the plant and making said assimilation more effective. The use of sulphates in the soil, in the presence of water, causes soil acidification which improves the assimilation of the micronutrients in alkaline soils.
