Ultrasol® ProP® Development is a formula that has been developed for the cell division phase, when plant organs are defining and developing, thanks to its NPK ratio of 2:1:2. This formula is enriched with magnesium to increase the efficiency of photosynthesis during and after the development stages. This formula is enhanced with ProP® technology, which improves the availability of phosphorus in the soil, optimizing its absorption by the plant.
