The synergic activity of chelated Iron along with Magnesium of B-Mix Fe/MgO quickly intensifies plant photosynthesis. In fact, B-Mix Fe/MgO has a high potency and curative power (or preventive) of any deficiencies. Chelation makes the Iron rapidly available and readily conveyable in plant tissues. Furthermore, magnesium is essential for the formation and accumulation of sugars in fruits. Since its high concentration of pure compounds, B-Mix Fe/MgO is particularly effective in reactivating plant metabolism in case of physiological stress and it can be also applied to ameliorate organoleptic characteristics (colour, taste, etc.) and fruit shelf life close to harvesting period.
