In China the time for Polysulphate is now. That was the main message at the recent International Potash Institute (IPI) symposium on polyhalite. This simple message was put in a compelling and memorable way for it to be understood, remembered and shared. The conference in China delivered it using the following perfect trio:
Context: Due to the negative impacts of excessive application of high concentration macronutrient NPK fertilizers, and the limited application of organic fertilizer, China is now paying much more attention to more balanced fertilization. This new focus provides an ideal opportunity for secondary nutrients fertilizer products, such as Polysulphate, which provide sulphur (S), magnesium (Mg) and calcium (Ca) to plants.
Science: At the event in China, evidence of the positive performance of polyhalite, as Polysulphate, in a wide range of crops was presented to the highly interested audience. Eleven key speakers revealed results of polyhalite research from China and elsewhere on a wide range of fruit, tuber, grain and leaf crops.
Practicality: Evidence from the podium was backed up with evidence from the field. The whole conference - over 150 researchers, advisors, farmers and fertilizer dealers - spent time looking at protected cropping of hami-melon with Polysulphate. The experience of seeing the crop and hearing from the Polysulphate user firsthand is compelling. The need for multi-nutrient fertilizer, the results from research and commercial practice are all pulled together on-farm.
