The uniquely formulated foliar nutrition Optima Phos2Grow redefines phosphorus fertilisation. Two complementary sources of phosphorus provide both a rapid and a long-lasting supply of phosphorus, regardless of (temporary) blockages in the soil caused by cold, pH or stress. The neutral product pH, incl. wetting agent and adhesion enhancer maximise uptake, efficiency and miscibility. This supports root development, the plant’s energy balance, tuber formation and yield at precisely the critical moments, making this fertiliser a practical and sustainable solution for robust potato cultivation.
