Introduction
Agriculture has been undergoing a profound transformation in recent years, driven by technological innovation and the need to produce more with fewer resources. Against this backdrop, drones for aerial treatments and aerial distribution are emerging as one of the most interesting and promising tools for the agricultural sector, despite the limitations to which they are subjected especially with regard to pesticide spraying.
Accuracy, reduced waste, lower environmental impact and greater safety for operators are just some of the benefits that are prompting more and more farms to look to the sky. From targeted distribution of pesticides and fertilizers to managing areas that are difficult to reach by traditional means, drones offer a new approach to crop protection and nutrition.
In addition, combining treatment drones with monitoring drones (see article on the iDrone), we get the full potential of harnessing aerial technology that provides eyes and arms to reduce the cost and time of crop operations, enabling higher yields and quality.
But how do drones really work for aerial treatments? In what contexts are they most effective, and what are the regulatory and technical limitations to be aware of? In this article we explore the role of drones in aerial distribution in agriculture, analyzing opportunities, practical applications and future prospects for a technology that is set to change the way we farm.

Advantages of using drones for treatments in agriculture
The use of drones in agricultural aerial treatments offers many advantages, especially from the perspective of precision agriculture and sustainability:

• Targeted distribution and high precision: drones allow plant protection products, fertilizers or biostimulants to be applied in a localized manner, only where needed, reducing waste and overdoses;
• Reduced environmental impact:through reduced distribution volumes, the ability to use prescription maps, and increased accuracy, chemical drift, water consumption, and contamination of soil and surrounding areas are decreased;
• Access to difficult areas:they are particularly effective in inaccessible areas, hilly or terraced terrain, tree crops and vineyards where the use of traditional machines is complex or impossible;
• Increased operator safety: theoperator does not come into direct contact with the chemicals, reducing health risks compared to manual or sprayer treatments;
• Speed and operational flexibility: drones can intervene quickly, even immediately after critical events (water stress, pest attacks), optimizing treatment time;
• Integration with digital data:can be integrated with vigor maps, satellite data or field sensors, making treatments part of an advanced decision-making system.

Limitations and critical issues of using drones for treatments in agriculture
Despite its many benefits, the use of drones for aerial distribution still has some technical, regulatory and economic limitations:

• Regulatory constraints: lhe legislation on aerial treatments is stringent and varies from country to country. In many cases, specific permits, pilot licenses and limitations on the products that can be used are required. In Italy, airborne phytosanitary treatments are banned but experimentation is allowed, at present, with stringent rules ;
• Limited load capacity: rispared to traditional means, drones have smaller tanks, making more flights necessary for large areas and increasing operational time. In addition, not secondary is the aspect of compliance with the maximum and minimum doses per hectare as per the label of plant protection products ;
• Flight autonomy: batteries have limited life, especially during treatments, requiring careful mission planning and frequent breaks for recharging or replacement;
• Upfront costs: theinitial investment can be significant, including drone, deployment systems, staff training, and maintenance;
• Sensitivity to weather conditions: wind, rain or high humidity can affect the accuracy of treatment or make it impossible to fly safely;
• Need for technical skills: effective use of drones requires specific skills in both piloting and agronomic management of treatments.

Agrobit and Scaligera Drones: a new business partnership for precision agriculture is born
Innovation in agriculture increasingly comes through the integration of advanced technologies, specialized skills and strategic vision. It is from this philosophy that the new commercial collaboration between Agrobit and Scaligera Drones was born, a partnership designed to offer farmers concrete, efficient and sustainable tools for crop management.
Thanks to this agreement, Agrobit expands its range of services for precision agriculture, integrating aerial distribution solutions using professional drones developed by Scaligera Droni, a reference reality in the field of UAV systems applied to agriculture.

I new aerial distribution services offered by Agrobit
Thanks to the commercial partnership with Scaligera Droni, Agrobit integrates in its offer a series of aerial distribution services based on the use of professional drones with high operational capacity. These solutions allow agronomic interventions to be carried out with high precision, rapid execution and reduced environmental impact, being particularly effective in contexts where access by traditional means is limited or inefficient.
Aerial liquid distribution allows uniform application of plant protection products, biostimulants and nutritional solutions, optimizing foliar coverage and minimizing drift phenomena and product waste. The high precision of the system allows targeted intervention on the areas really in need, improving the effectiveness of the treatment and the overall sustainability of the intervention.
Alongside liquid treatments, drone technology also allows aerial distribution of solid materials such as granular fertilizers, seeds and pollen. This type of application is particularly advantageous for localized operations, precision seeding or operations on complex areas where traditional distribution would be uneven or economically disadvantageous.
A further area of application concerns the aerial distribution of beneficial insects and mites, which is essential for the implementation of integrated and biological pest management strategies. The use of the drone enables a controlled and homogeneous release of beneficial organisms, improving the effectiveness of biocontrol and promoting a more sustainable approach to pest management.
Biocontrol services are particularly effective in containing pest problems such as red spider mite and corn borer, permitting timely and targeted interventions, reducing the use of chemicals and preserving the balance of the agroecosystem.
Finally, a key element of the offering is variable-rate distribution, which represents one of the highest levels of evolution in precision agriculture. Through integration with prescription maps, agronomic data and field analysis, it is possible to dynamically modulate the amounts distributed according to the actual needs of the crop. This approach maximizes input efficiency, reduces operating costs and improves crop yield and quality.
