Phosfy Mag 307 brings Phosphorus in a form particularly and mobile, able to direct itself with great elasticity both along the ascending and descending flows of the plant. The product is recommended in fertigation, alone or in combination with other elements (nitrogen and potassium), in the first phase of plant growth or post-transplant, since it reinforces the structure of the tissues, prepares the plant for optimal flowering and, consequently, qualitatively and quantitatively high fruiting. Moreover, Phosfy Mag 307 is enriched with Magnesium which, being vital for the photosynthetic process, is essential for obtaining quality productions.
