NUTRI CALMAG (Calcium Magnesium and Boron)

Magnesium and Boron

Fertilizer EC
Solution of Calcium Nitrate with Magnesium  and Boron

NUTRI CAL MGis a liquidfertilizer, produced with raw materials of very high quality,rich in calcium and magnesium. Calcium has a fundamentalfunction in the neutralization of organic acids. It also takespart in the metabolism, regulating the colloidal state ofprotoplasm. In contrast with potassium, it acts in theprocesses thatregulate transpiration and water balance, improvingplasma contraction and diminishing water absorbency. NUTRI CALMG is fundamental for cellular division; it is aconstituent of an enzyme, maltase; it’s important formeristems growth and it is strongly required by the plant duringpollen formation.
Magnesium lack causesreduction in meristems growth, delay in the young leavesdevelopment, which become deformed and chlorotic and thennecrotize on the margins. Magnesium is instead a fundamentalcomponent of chlorophyll and has a great relevance in thevegetative and productive development of plants. It also takespart in the nitrogen absorption, in the photosynthesis and inthe formation of pectins and carotenoids.
