Magnesium

Like all vineyards in France, our vines need 8 to 20 kg / ha / year of magnesium.

Indeed, magnesium is an important element for the composition of chlorophyll and pectins. Taken as Mg2 +, it neutralizes certain acid functions, regulates osmotic pressure and is determined to be a phosphorylation enzyme activator. In other words magnesium has a major role in respiration, synthesis of carbohydrates and proteins and it intervenes in the enzymatic reactions of the metabolism of sugars. Also, it has an important role in the absorption of other nutrients: it promotes the assimilation and transport of phosphorus in the plant. Finally, it is antagonist with potassium K.

It should be noted that the calcareous soils are the richest in magnesium.
