For small to medium-scale commercial farmers and agricultural contractors, spray season brings a familiar pressure: covering enough hectares, quickly enough, without operational costs eating into the margin. Traditional spraying methods and smaller drone systems often struggle to keep pace with the size of modern farming and contracting operations. This article about the DJI Agras T70P looks at how large-capacity spray systems and higher flight speeds are changing what a single day’s spraying can achieve.
By the end of this article, you’ll understand how tank capacity and flight speed work together to reduce labour hours, why faster coverage doesn’t mean less precision, and what this shift means for the cost of running a spray operation season after season.
The Real Cost of Limited Coverage
Every hour spent refilling, repositioning, or making extra passes over a field is an hour not spent covering new ground. For contractors managing multiple clients or farmers working against a tight application window, limited coverage capacity translates directly into higher labour costs and slower turnaround on jobs that need to happen at the right time, not whenever equipment allows.
Smaller spray systems, whether manual or drone-based, mean more refill stops and more flights to treat the same area. Over a full season, those extra stops add up to real time and real cost, particularly when weather windows for spraying are already limited.
Larger Tank Capacity Means Fewer Interruptions
A larger spray tank changes the maths on a spray day. With a 70-litre tank capacity, the DJI Agras T70P carries significantly more product per flight than smaller systems, which means fewer trips back to the mixing station and more continuous time spent actually treating the crop.
For contractors billing by the hectare, fewer interruptions mean more billable coverage per day. For farmers managing their own spraying, it means finishing critical applications within the ideal window rather than stretching a job across days it doesn’t need to take.
DJI AGRAS T70P
The DJI Agras T70P is a versatile agricultural drone built for spraying, spreading, and lifting with maximum efficiency on medium to large fields. With a 70 L spray tank, 100 L spreader, 65 kg lift capability, advanced Safety System 3.0 obstacle sensing, fast operation speeds, and robust transmission, it delivers powerful performance and safer autonomous field coverage.
Speed Without Sacrificing Precision
Coverage capacity is only half the equation. Flight speed determines how quickly that capacity gets put to work across a field. With flight speeds of up to 14 m/s, the Agras T70P covers ground substantially faster than manual spraying or older, smaller drone systems, without requiring operators to sacrifice application accuracy.
This is where the efficient spray system matters just as much as the tank size. Consistent droplet distribution and adjustable spray width mean that faster flight speeds don’t come at the cost of even coverage. Farmers and contractors get both: more hectares treated per hour, and product applied where it’s needed.
Reducing Labour Costs Across a Season
Labour is one of the largest variable costs in any spraying operation, whether that’s an operator’s time, ground crew supporting refills, or the opportunity cost of equipment sitting idle between passes. When a single flight covers more area with fewer stops, the labour required to complete a given job drops accordingly.
For contractors, this means the ability to take on more clients within the same operating window. For farmers managing their own equipment, it means spray days that require less manpower to complete, freeing up labour for other seasonal demands.
Matching Capacity to Your Operation
Not every farm or contracting business needs the same tank capacity or flight profile. Smaller operations may find a 70-litre system strikes the right balance between coverage and manoeuvrability, while larger commercial operations covering extensive hectares may benefit from stepping up to a higher-capacity option like the DJI Agras T100. As a distributor of DJI’s agricultural range, we help farmers and contractors work through this comparison to find the configuration that matches their actual operational scale, rather than over- or under-investing in capacity they don’t need.
DJI AGRAS T100
The DJI Agras T100 is a next-generation agricultural drone built for large-scale farming, featuring a 100-litre spray tank, 150-litre spreader, and the ability to cover up to 12 hectares per hour. With advanced LiDAR, radar, and Penta-Vision obstacle sensing, plus rapid-charging intelligent batteries, it delivers powerful, efficient, and safe operations for modern agriculture.
Frequently Asked Questions
Does a larger spray tank affect flight time? Tank capacity and flight time are balanced within the aircraft’s overall payload limits, and the Agras T70P is engineered to maintain efficient operation even when carrying a full 70-litre load.
Is faster flight speed suitable for all crop types? Adjustable spray width and droplet settings allow the system to be tuned for different crops and field conditions, so higher flight speeds can be matched to the application requirements of the job.
How does reduced coverage time affect overall spraying costs? Fewer refill stops and faster coverage per flight reduce the labour hours needed to complete a spraying job, which lowers the overall operational cost of each application.
Ready to Increase Your Spray Coverage?
Large-capacity spray systems and higher flight speeds are giving farmers and contractors a practical way to cover more ground, reduce labour costs, and complete applications within tighter seasonal windows.
