Researchers at the Stavropol State Agrarian University are developing new protocols for using agricultural drones to apply crop protection products. The project is part of the Agroengineering of the Future world-class research center, aiming to optimize spraying parameters and improve the efficiency of chemical use in crop production.
The study focuses on the relationship between droplet size and coverage. Reducing droplet diameter from 300 to 150 micrometers increases the total number of droplets eightfold from the same volume of liquid. However, researchers note that smaller droplets are more susceptible to wind drift, while larger droplets may provide better deposition under specific conditions.
The team is testing various flight altitudes, speeds, and liquid flow rates to determine their impact on crop protection. They utilize laser particle analyzers in both laboratory and field settings to measure droplet size and assess how factors like rotor-generated airflow and plant density affect the final distribution of chemicals.
The ultimate goal of the research is to establish scientifically grounded regulations for drone-based agricultural operations. According to Rector Vladimir Sitnikov, these standards will help farmers maximize the effectiveness of their treatments and ensure more rational use of plant protection products across different types of crops.
