low oil yield on Pelargonium Graveolens
Quick answer
If your Pelargonium Graveolens has low oil yield, the most likely cause is: Pelargonium graveolens (geranium) herb and essential oil yield increases proportionally with NPK fertilization up to full recommended dose (600 kg/fad ammonium sulfate + 300 kg/fad calcium superphosphate + 150 kg/fad potassium sulfate).
Start here:
- 1. 1. Apply full NPK dose: 600 kg ammonium sulfate + 300 kg calcium superphosphate + 150 kg potassium sulfate per fad
- 2. 2. Split N application into 4 equal portions across the growing season
Why Pelargonium Graveolens gets low oil yield
Pelargonium graveolens (geranium) herb and essential oil yield increases proportionally with NPK fertilization up to full recommended dose (600 kg/fad ammonium sulfate + 300 kg/fad calcium superphosphate + 150 kg/fad potassium sulfate).
How to reverse low oil yield on Pelargonium Graveolens
- 1
1. Apply full NPK dose: 600 kg ammonium sulfate + 300 kg calcium superphosphate + 150 kg potassium sulfate per fad
- 2
2. Split N application into 4 equal portions across the growing season
- 3
3. Combine with foliar spray of moringa leaf extract at 6 g/L for enhanced herb yield
- 4
4. Four sprays during growing season, one week after NPK additions
Keep low oil yield off this Pelargonium Graveolens
For optimal geranium oil production, apply 100% NPK recommended dose in 4 equal portions (December, March, June, July). Half dose combined with moringa extract at 6 g/L can replace full chemical fertilization.
