The Vitalize 16-5-16 has been developed to have a NPK analysis that provides an acidifying response. 16-5-16 has added seaweed and magnesium to improve plant stress relief during the main growing season. The technological formulation also provides quick green up as well as slow release technology for added longevity.
 
Impact Vitalize 16-5-16 provides good cool temperature response and extended longevity from the added methylene urea, whilst moisture provides a quick breakdown of the granules. Impact Vitalize 16-5-16 should be applied at 20-40 g/m², the 20 kg bag will cover 500-1,000 m² and it can be used from March to September.
