Phosfy Mag 307 is characterised by the particularly active nature of its Phosphorus, which is mobile and able to direct itself with great elasticity both along the ascending and descending flows of the plant. Phosphorus is essential for the crop growth, both in the early stages of development and after flowering, to accelerate production ripening and improve its qualitative characteristics Thanks to the presence of Potassium, Phosfy Mag 307 directly influences the quality of the final production. Actually, Potassium is an osmotic pressure regulator and contains excessive growth. Finally, Phosfy Mag 307 is enriched with Magnesium which, being vital for the photosynthetic process, is essential for obtaining quality productions.
