How DJI Agras Drones Are Used in Sugar Cane Fields

WHERE IT'S GROWN

Far North Queensland to Northern NSW

Sugar cane runs along 2,100 km of Australia's eastern seaboard -from Mossman, north of Cairns, through the Queensland coast to the Northern Rivers of New South Wales. Commercial production here dates back to the 1860s

The Australian Sugar Cane Industry

Australian cane production at a glance

Australia’s sugar cane industry spans five major growing regions, from Mossman in Far North Queensland to the Northern Rivers of NSW, supplying 21 sugar mills along the eastern coast. Around 29.9 million tonnes of cane are harvested across 341,084 hectares each year, supported by approximately 3,700–4,000 farm businesses. With Queensland farms typically ranging from 40 to 250 hectares, sugar cane represents a significant agricultural industry with diverse operational requirements.

Raw sugar -grown locally, sold globally

Almost all Australian cane is processed into raw sugar, with around 80% exported to international markets including South Korea, Japan, Indonesia and the United Kingdom. The industry contributes approximately $2.5 billion annually to the Australian economy, highlighting the importance of efficient and adaptable farming practices and the potential for precision agriculture.

WHY AGRAS FOR SUGAR CANE

Ground-rig operations can cause repeated wheel-traffic damage to sugar cane stools, as typical cane rows are spaced at around 1.5 m while ground-rig tracks average 1.83 m wide. Repeated passes can compact the soil and damage roots, reducing ratoon yield over successive crop cycles. In comparison, DJI Agras drones operate without ground contact, allowing treatment on wet or waterlogged fields while providing precise chemical application and RTK-guided passes with up to 10 mm positioning accuracy.

TREATMENT PROGRAM


When and where DJI Agras can be applied

The plant crop runs 0-18 months from planting to harvest, and the spray & spreading program follows the same window -not a generic 12-month calendar. Each pass is a candidate for drone application, particularly when paddocks are too wet for a ground rig.

Herbicide and fertiliser applications occur at several stages through the crop cycle. Fast, accurate drone passes help ensure treatments land at the right time while minimising crop damage

TREATMENTS -SPRAYING

Herbicide: advantages and field results

Herbicide applications are an important part of sugar cane establishment and early tillering, helping control weeds during the crop’s most vulnerable stages. DJI Agras drones provide a precise and flexible alternative for these treatments, with adjustable spray widths, droplet sizes and RTK positioning accuracy. Their rapid deployment and ability to operate after rainfall can help reduce soil compaction and improve application timing, supporting better weed control, healthier crop establishment and more efficient input use.

TREATMENTS -SPREADING

Fertiliser and seed / seedling inputs

Beyond liquid spraying, the DJI Agras T100 can be equipped with a spreading hopper for granular applications such as fertiliser, seed treatment and targeted gap-filling. With a 100 kg operating payload, up to 400 kg/min discharge rate and a 3–10 m effective spreading width, the T100 can deliver granular inputs efficiently across the paddock. This provides an alternative when ground spreader access is limited, particularly in wet conditions, while targeted applications can help avoid unnecessary blanket spreading and improve input efficiency.

COST FOR USING AGRAS T100

Getting the job done in the window that matters

  • Cost: $50-60ha

  • Wet-ground access: Excellent –flies and lands on soft ground

  • Compaction risk: None (aerial)

  • Typical daily coverage: up to 160 ha / day

  • 20+ ha/hr — Typical work rate for large broadacre paddocks at 20 L/ha.

  • ~7 hours — Estimated time for the T100 to cover a 150 ha block.

  • 8–9 min recharge — Faster battery turnaround helps reduce downtime between loads.

  • Access after rain — Can operate when wet conditions prevent ground rigs from entering paddocks.

  • Less ground damage — No wheel ruts or soil disturbance during treatment.

  • Better timing — Helps growers make the most of narrow treatment windows and complete time-critical work when conditions are right.
