The present invention relates to an inorganic solid nutritive composition comprising at least one polyphosphate and at least one source of iron as micronutrient, wherein said composition is water-soluble and comprises an iron content of between 0.1% and 5% by weight of iron relative to the total weight of said solid composition.

Iron-based nutritive composition

This invention pertains to a process for manufacturing an iron-based nutrient composition comprising at least the steps of supplying an iron source and a phosphate source containing at least one polyphosphate, further comprising a mixing step of the iron source with the phosphate source. The iron source and phosphate sources being in their solid phase, the mixing of the two being solid-solid mixing, leading to the obtaining of a water-soluble, iron-based solid nutrient composition.

The present invention relates to an inorganic liquid nutritive composition comprising at least one aqueous phase, a polyphosphate and at least one source of iron as micronutrient, having a P/Femolar ratio of between 5 and 50.
