Bio-Plex™ is a foliar fertiliser that produces a complex multi-dimensional growth response. It includes finely tuned nitrogen-fixers which utilise carbon exudates from the leaf to fix nitrogen from the atmosphere directly into the leaf and a range of microbes that release natural growth promotants such as gibberellic acid cytokinins auxins and indole-acetic acid. Nutri-Life Bio-Plex™ contains species that produce vitamins including the B group vitamin E and vitamin C. It also contains a range of organisms that secrete a substance that can help maintain balance of beneficials on the leaf surface.
