FOSS Mg is a product developed for the prevention and correction of magnesium deficiencies, which also acts as an inducer of the natural defenses of plants.

FOSS Mg favors the root development and potentiates the flowering, fruit setting and ripening processes.
FOSS Mg provides the plant with a high amount of magnesium, the main constituent of the chlorophyll molecule, which favors photosynthesis. In addition, magnesium improves the absorption of other elements such as phosphorus and acts as an enzyme activator.
FOSS Mg provides the plant with a high phosphorus content in the form of phosphite ion, which stimulates natural defenses. FOSS Mg provides resistance to certain fungi, as well as strengthening the stem and roots against pathogen attacks. FOSS Mg has a systemic action: it is rapidly absorbed and distributed to all parts of the plant.
