Akar Plus MZ is an innovative fertilizer, with high adhesiveness and ability to distribute itself on treated surfaces, which brings zinc and manganese to the plant. These are two very important nutrients that intervene in numerous metabolic processes of the plant, in particular, those that respond to environmental stress. Furthermore, thanks to the peculiar properties of its components, of a polymeric nature, Akar Plus MZ increases the endogenous capacity of the plant to resist the main stress factors (temperature and/or water). In fact, Akar Plus MZ performs a dual function: it optimizes the transpiratory processes of the plant in stressful conditions, improving the water balance between the inside and outside of the plant, and it stimulates the production of secondary metabolites responsible for endogenous plant resistance responses.
