Fertilizer by crop
Tapped rubber needs fertilizer twice a year, 1–1.2 kg/tree/year in total, per Department of Agriculture guidance. Our 15-7-18 matches the recommended formula exactly.
Coloured bars show when to apply at each stage. The current month is highlighted.
May – Jun
Feed the new canopy, restore the tapping panel and prepare for the new tapping season.
Recommended
Rate & method: 15-7-18 at 500–600 g/tree, broadcast across the plot about 1 m from the tree rows.
Or choose
Clear weeds first and apply on moist soil.
Sep – Oct
Build reserves before the dry season for good latex flow and higher dry-rubber content.
Recommended
Rate & method: 15-7-18 at 500–600 g/tree.
Or choose
Trees due for felling within 3–5 years can have fertilizer reduced or stopped.
Add every time you fertilize
Mor Rubber adds calcium, magnesium and orthosilicic acid. Apply it with your NPK each round for softer bark, easier tapping and healthier latex vessels.
Also twice a year at the start and end of the rains. On loam use 16-8-8; on sandy soil use 15-7-18. Per application by age: 2–17 months 60–120 g, 2–3 years about 190 g, 4–6 years about 250 g per tree.
Keep your usual formula twice a year and add Mor Rubber each round.
15-7-18 at the start and end of the rains, 500–600 g/tree each, plus Mor Rubber every round.
At the start of the rains, broadcast orthosilicic acid powder to correct pH a month before fertilizing, then follow the programme.
