Romazin P is a mineral fluid fertiliser based on phosphorus activated with magnesium that grants the maximum availability of both nutrients also at low temperatures and during the most critical crop stages. The special formula favors the quick assimilation of phosphorus and it is ideal for promoting the root development; moreover, magnesium content improves and increases photosynthesis while zinc (in chelated form) is a vegetative boost for plants and helps the assimilation of magnesium itself.
