The fertiliser obtained substantially improves nutrient absorption in plants where it is applied.The invention relates to a new product for agricultural use, which changes maximum crop yield with minimal environmental impact, allows the doses of fertilising units providing potassium, calcium, magnesium, iron, zinc, manganese and copper to be reduced, and can be incorporated into the soil by means of fertilisation, using sprinkler irrigation or drip irrigation.
