Before tapping, apply a 10:10:4:1.5 NPK-Mg mixture on a schedule from the 3rd month (225 g per plant) rising to 450–550 g per plant, in April–May and September–October; from the 5th year until tapping, 400 kg/ha a year in two doses. For trees under tapping: 10:10:10 mixture at 900 g per tree (300 kg/ha) a year in two splits; add 10 kg magnesium sulphate per 100 kg of mixture if magnesium is deficient.
