Magnesium sulphate with iron
EC inorganic fertiliser. Recommended both as preventive and curative treatment, so as to correct magnesium deficiencies. Deficiencies of Mg may produce yellowing and subsequent browning, by beginning from the tips of the leaves and spreading towards the branch. Instead, when produced in fungi, the symptoms of browning begin on the basis of the plant and spread towards the tree crown. In this case, you shall have to apply Fósbel Jardín.
