Folanx® Mg8 - the micronized magnesium carbonate fertilizer suspension

Nutrients and their functions: Magnesium (Mg)

Because of its high mobility, magnesium is not readily available especially in sandy, acid soils, or in soils with a high lime concentration or an extraordinarily high potassium content. Cold and wet soils reduce the availability of magnesium.
Magnesium is one of the most important components of the cell structure. In addition to calcium, is is bonded in large amounts in the pectin structure and is the most important component of chlorophyll, and is thus an important participant in the metabolic processes inside the plants. Magnesium controls the osmosis pressure and promotes the uptake of phosphorus.
Visible symptoms of magnesium deficiency mean that reductions in crop quality and yield are likely. An optimized supply of magnesium improves the vitality of the plants, the quality of the fruit and the yield.
General symptoms of deficiency
Magnesium deficiency is expressed by yellow and later brown necrotic areas between the veins in the leaves. The older leaves are primarily affected. The plant can drop its leaves prematurely.
A magnesium deficiency is reflected by different symptoms in the vines. Red-wine varieties, unlike the light yellow spots typical of white-wine varieties, exhibit discolored reddish spots with leaf edges that turn from green to white.
The consequences of a magnesium deficiency include premature leaf drop and aging of the vines. A magnesium deficiency also promotes grape stalk dieback.
Fruit farming
A magnesium deficiency reduces the formation of chlorophyll in the leaves. The transport of nutrients and energy is also reduced. Fruit formation and quality are also adversely affected, and the bud set for the following year is reduced.
However, the incorporation of excessive amounts of magnesium in the pectin structure of the fruit can have negative consequences, because it blocks the important bonding sides of the calcium in the pectin chains and can thus cause a premature ripening or reduction of the solidity of the fruit. The susceptibility of the fruit to diseases while in storage is also increased.
According to the South Tirol Advisory Council, the Kanzi® variety is particularly susceptible to magnesium deficiency.
Berry farming
As in all other crops, the older leaf surfaces become discolored, starting from the edges, and tend toward necrosis. The fruit ripens poorly, softens earlier, remains small and is susceptible to diseases.
Root growth is reduced, and consequently the growth of the entire plant is held back. For strawberries, the growth of runners is reduced, and fewer and sometimes very weak offspring plants are produced.
