PROXYBiostimulation and Foliar Nutrition by Drone
Foliar-applied microelements — iron, manganese, zinc, boron — can increase yield by 10-15% if applied at the right time. The drone ensures uniform coverage without wheel tracks in the crop, especially during critical stages when the plant needs supplementary nutrients the most.
How it works
Biostimulants and foliar fertilizers are diluted per the recipe (amino acids, chelated microelements, algae extracts). The drone applies the solution at high concentration (8-12 L/ha), ensuring rapid absorption through stomata. Ideal timing: early morning or evening when stomata are open.
Comparison: Drone vs. Tractor
| Criteria | Drone | Tractor |
|---|---|---|
| Cost per hectare | 90 RON + VAT | 50-60 RON |
| Crop loss | 0% | 3-5% |
| Coverage uniformity | Excellent | Variable |
| Schedule flexibility | Morning/evening/night | Daytime only |
| Wet terrain access | Yes | Limited |
Economic analysis
ROI of foliar nutrition (wheat, 5 t/ha):
At a cost of 90 RON/ha (application) + 50-80 RON/ha (product), the total investment of 140-170 RON/ha brings an extra 500 RON/ha in yield. ROI: 3-4x.
When you need this
Biostimulation and foliar nutrition by drone are recommended in the following situations:
- Wheat at BBCH 37-49 — foliar nutrition during boot-heading stage
- Heat/drought stress — amino acid biostimulants help plants cope
- Microelement deficiencies — iron, manganese, zinc visible on leaves
- Sunflower at budding — boron for pollination
Why ProxyDrone
Our operators understand that timing is everything for foliar nutrition. Book 24-48h ahead, choose the optimal weather window, and treatment happens at the exact right moment.
Frequently Asked Questions
What additional yield does foliar nutrition provide?
Applied at the right time, foliar nutrition with microelements can increase yield by 10-15%. For wheat, that means an extra 0.5-0.75 t/ha.
What is the ROI of foliar nutrition by drone?
The total investment of 140-170 RON/ha (application + product) brings an extra approximately 500 RON/ha in yield. ROI: 3-4x.
When is the optimal application time?
Early morning or evening when stomata are open. For wheat, BBCH 37-49 (boot-heading stage) is the critical window.
Can biostimulation be combined with other treatments?
Yes, biostimulants and microelements can be combined with compatible fungicides or insecticides in a tank mix, saving an additional pass.
