Fertilizer-Comparison on ficus
What's Happening
Chemical NPK fertilizers provide immediate nutrient availability with 100% concentration achieving optimal vegetative growth (67cm height, 0.79mm stem diameter, 19 leaves per transplant), while pure compost at 75% concentration without bio-fertilizer supplementation resulted in significantly reduced growth metrics (38cm height, 0.37mm diameter, 7 leaves)
How to Fix It
- 1
Apply 100% recommended NPK chemical fertilizer (10g N, 8g P2O5, 6g K2O per transplant) for maximum vegetative growth
- 2
For reduced chemical input while maintaining 95% growth efficacy, use 75% NPK + 25% compost combined with bio-fertilizers (Nitrobein, Phosphorene, Potassein)
- 3
Avoid pure organic compost exceeding 50% of total fertilization without bio-fertilizer supplementation as it reduces growth parameters by 40-60%
How to Prevent It
Test soil nutrient baseline before fertilization; for houseplants in containers, maintain NPK at full recommended dose or use 75% chemical NPK + 25% quality compost with bio-fertilizer inoculation to prevent nutrient deficiency stunting.
