As Australian cane growers face tighter margins, unpredictable weather, and increasing pressure to improve nutrient efficiency, traditional ground-based application methods are being re-evaluated. Foliar nutrition has long been recognised as a powerful tool for correcting deficiencies and boosting crop performance—but how nutrients are delivered is just as important as what is applied.
Across Far North Queensland, drone-based foliar feeding is emerging as a precise, efficient, and soil-friendly solution for sugarcane nutrition. As the FNQ dealership for XAG agricultural drones, Aztec Dynamics is supporting growers with advanced aerial application technology designed specifically for Australian conditions
The Role of Foliar Nutrition in Cane Production
Sugarcane is a high-demand crop, requiring balanced macro and micronutrients throughout key growth stages. While soil-applied fertilisers remain foundational, foliar feeding provides a rapid and targeted method to correct deficiencies, stimulate tillering, enhance chlorophyll production, and support ratoon recovery.
Foliar applications are particularly effective during:
Early vegetative growth
Post-harvest ratoon establishment
Periods of waterlogging or drought stress
Micronutrient deficiency events (e.g. zinc, manganese, iron)
Because nutrients applied to the leaf are absorbed directly into plant tissue, response times are faster compared to soil-based uptake. However, coverage, droplet size, and application timing are critical to success—areas where drone technology provides a measurable advantage.
Precision Application with the XAG Pro 150
The XAG Pro 150 agricultural drone, supplied and supported by Aztec Dynamics, is engineered for high-accuracy, low-volume aerial application
Equipped with advanced terrain-following radar and intelligent flight control systems, the Pro 150 maintains consistent height above dense cane canopy—even in undulating paddocks.
For foliar feeding, this precision translates to:
Uniform droplet distribution across the leaf surface
Reduced runoff and improved nutrient adhesion
Lower spray volumes without compromising coverage
Minimal drift in variable wind conditions
Unlike high-clearance ground rigs, drone application eliminates wheel-track damage in ratoon cane and avoids soil compaction—an important consideration in wet tropical soils where compaction can restrict root development and reduce yield potential.
Efficiency Gains in the Field
Drone-based foliar feeding allows growers to respond quickly within narrow spray windows. In tropical regions where rainfall and humidity frequently disrupt ground operations, aerial access can make the difference between timely nutrient correction and yield loss.
Operational efficiencies include:
No need for paddock access roads or dry soil conditions
Reduced labour requirements
Faster mobilisation between blocks
Targeted treatment of specific zones rather than blanket spraying
Intelligent route planning and variable-rate capability allow operators to treat only the areas requiring nutritional support, aligning with precision agriculture principles and reducing input costs
Some growers integrating drone foliar programs report measurable reductions in total spray volumes, alongside improved nutrient-use efficiency—supporting both economic and environmental sustainability.
Protecting Soil While Feeding the Crop
In cane production systems, soil structure is a long-term asset. Heavy machinery traffic—particularly during wet periods—can cause compaction, rutting, and reduced infiltration. Drone foliar application removes this risk entirely.
By delivering nutrition from the air, growers can:
Preserve soil structure
Maintain root-zone aeration
Avoid crop damage from ground equipment
Improve long-term paddock productivity
This approach aligns with broader climate-resilient farming strategies that prioritise soil health while maintaining yield performance
Built for Australian Conditions
Extreme heat, humidity, and rugged terrain are standard operating conditions in North Queensland cane regions. XAG agricultural drones are designed with high-efficiency cooling systems and industrial-grade components, allowing reliable performance during peak summer periods
For cane growers managing large or remote properties, this reliability ensures that foliar nutrition programs stay on schedule—especially during critical growth stages when nutrient uptake directly influences biomass accumulation and sugar content.
Smarter Technology. Healthier Cane. Stronger Yields.
Foliar feeding with drones offers a practical pathway toward more precise, responsive, and sustainable cane nutrition. As climate variability and economic pressures intensify, efficient nutrient delivery will play an increasingly critical role in maintaining productivity.
By combining advanced XAG Pro 150 drone systems with agronomic insight, Aztec Dynamics is supporting the next evolution of sugarcane nutrition—one flight at a time.
