UAV Foliar Nutrition Solution
Drone grade Monopotassium Phosphate (MKP)
UAV spraying has become a widely adopted practice in modern crop management. Under low-volume aerial conditions, fertilizer quality directly influences spray stability, nutrient efficiency and crop safety, particularly when using precision foliar inputs such as Drone grade Monopotassium Phosphate (MKP).
Drone grade Monopotassium Phosphate (MKP) is formulated to meet the operational requirements of low-volume UAV spraying systems, where dissolution speed, purity and compatibility are critical for consistent aerial performance.
Technical Basis for Recommended Concentration
According to publicly released guidance from the National Agro-Technology Extension and Service Center of China, the recommended working concentration for foliar spraying programs using UAV systems is:
- 2–0.3% (2–3 g/L)
- Spray volume: 1.5–3 L per mu
- Equivalent to: 22.5–45 L per hectare
Under these parameters, the equivalent application rate of Drone grade Monopotassium Phosphate (MKP) per treatment is:
- 45–135 g per hectare
These values reflect a low-volume, precision supplementation model suitable for UAV aerial operations, where Drone grade Monopotassium Phosphate (MKP) supports controlled nutrient delivery without increasing spray load.
Because crop species, growth stages and environmental conditions vary, actual application rates of Drone grade Monopotassium Phosphate (MKP) may differ. Growers are advised to consult local agricultural extension specialists or crop advisors when adjusting concentration or frequency of Drone grade Monopotassium Phosphate (MKP) in field programs.
We will continue to publish field performance data and crop-specific application cases for Drone grade Monopotassium Phosphate (MKP) to support practical reference and field validation.
