Unique technological process is a two-stage process. In the first stage, the crystal structure of polyhalite, which 'binds’ the desired sulphates, is broken down. Only the raw material treated in this way undergoes further processing and finally acquires the form of fully reactive granules, perfect in their form for full penetration into the soil. Other formulations based on polyhalite can only be compared to the raw material of Belenus® and Vervactor® fertilisers, which is the start of their production process. The method we use means that the GoudenKorrel® line fertilisers almost double the potency of polyhalite. We will not tell you that we are the only ones who recognise the power contained in polyhalite, but we are the only ones who start where others end!
