npk fertilization on Ficus
Quick answer
If your Ficus has npk fertilization, the most likely cause is: Full NPK fertilization (100% chemical NPK at 10g N, 8g P, 6g K per fig transplant) maximizes vegetative growth in Ficus carica Sultani cv. by meeting all nitrogen requirements for protein, nucleic acid, and enzyme synthesis; nitrogen constitutes proteins, nucleic acids and enzymes (Nijjar 1985) and biofertilizers require organic matter to stimulate activity.
Start here:
- 1. 1. Apply ammonium sulphate (20.5% N), calcium superphosphate (15% P2O5), and potassium sulphate (48% K2O) at 10:8:6 g per transplant annually for 1-year-old Sultani fig
- 2. 2. Split application into three equal doses: mid-February (vegetative growth initiation), March (active growth), and April (pre-establishment)

How to reverse npk fertilization on Ficus
- 1
1. Apply ammonium sulphate (20.5% N), calcium superphosphate (15% P2O5), and potassium sulphate (48% K2O) at 10:8:6 g per transplant annually for 1-year-old Sultani fig
- 2
2. Split application into three equal doses: mid-February (vegetative growth initiation), March (active growth), and April (pre-establishment)
- 3
3. Supplement with bio-fertilizer cocktail (Nitrobein containing Azotobacter, Phosphorene containing arbuscular mycorrhiza, Potassein containing Bacillus pasteurii) at 10 mL per transplant
- 4
4. For organic alternative: replace up to 50% NPK with compost (C:N ratio 17.6, containing 1.5% N, 0.6% P, 1.32% K)

5. Monitor leaf nitrogen content target of 2.5-3.0% dry weight; adjust NPK rates if leaf N falls below 2.0%
Keep npk fertilization off this Ficus
For Ficus carica Sultani fig transplants: apply full NPK dose fractionated into three equal portions (mid-Feb, March, April); if reducing chemical fertilizer, maintain minimum 75% NPK + 25% organic compost + bio-NPK (Nitrobein, Phosphorene, Potassein) to preserve growth parameters.
