Overview of T50 drone technology

Introducing the DJI Agras T50

The DJI Agras T50 is the newest generation in DJI’s agricultural UAV lineup, built for large-scale pesticide and fertilizer spraying. It features dual millimeter-wave radar, 360° obstacle avoidance sensors, and a high-precision RTK positioning system for accurate flight paths. With a takeoff weight exceeding 50 kg and a 40-liter tank, the T50 delivers twice the spraying capacity of the previous T40 model.

Technical configuration and dual-radar system

The T50 combines millimeter-wave dual radar with vision sensors capable of detecting obstacles within a 50-meter radius. Its carbon fiber frame and high-torque motors maintain stability even in strong winds.

Key specifications:

  • Tank capacity: 40 liters
  • Max spray rate: 16 L/min
  • Coverage area: ~25–30 ha/hour
  • Navigation: RTK + AI Vision system

→ These specs enable high-precision spraying while minimizing chemical waste.

Enhanced spraying and RTK navigation

The upgraded dual high-pressure nozzles produce ultra-fine droplets for better leaf adhesion and chemical efficiency. With RTK guidance, the T50 follows preprogrammed routes with only 2–3 cm deviation, maintaining accuracy even on hilly terrain - a major leap for all-terrain stability and nighttime operation.


Real-world spraying performance of the T50

Tank capacity and coverage per flight

With its 40-liter tank, the T50 can cover 1 hectare in just 2–3 minutes. Dual spray nozzles and high-pressure pumps distribute liquid evenly while reducing water usage by 25% compared with manual spraying.

Average spray speed and coverage area

The T50 achieves a spray speed of 7 m/s at an altitude of 2–3 meters, ensuring fine, even mist distribution across the crop canopy. With a 9-meter spray width, it is particularly efficient for large-scale rice fields.

Spraying effectiveness on different crops

Uniform distribution and chemical efficiency

Equipped with dual electromagnetic nozzles, the T50 disperses ultra-fine droplets, saving 15–20% of pesticide usage. Its flow-control sensors maintain constant pressure throughout each flight for consistent spray volume.

Effectiveness on rice and industrial crops

In field trials across the Mekong Delta, the T50 achieved over 95% pest-control efficiency on rice. For tall crops like coffee and pepper, its 6–7 m spray height ensures full canopy coverage and uniform chemical absorption.

High-pressure misting and yield improvement

The 8-bar high-pressure spray system generates ultra-fine droplets that penetrate deeply into foliage. As a result, average crop yields increased by 10–15%, while reducing chemical residues and environmental pollution.


Economic efficiency and ROI

Investment and operating cost comparison

The DJI Agras T50 is priced between 320–350 million VND, roughly 15% higher than the T40, but it delivers nearly 30% higher productivity. Reduced electricity and pesticide consumption lower long-term operational costs.

Payback period

With an average workload of 20 hectares per day, the T50’s ROI period is about 6–8 months - roughly two months faster than the T40, making it a compelling choice for cooperatives and large-scale farms.

Economic benefits for farmers and cooperatives

By replacing manual spraying (costing ~300,000 VND/ha) with drone spraying (~80,000–100,000 VND/ha), a 100-hectare farm can save over 20 million VND per season. Combined with safer working conditions and consistent yields, the T50 is becoming a preferred option in the Mekong Delta.


Operational stability and user experience

360° obstacle avoidance and autonomous flight

The omnidirectional sensors detect trees, poles, and terrain in real time. With the DJI SmartFarm app, users can automatically map spraying zones with just a few taps, improving precision and safety.

Battery durability and flight endurance

Its 30,000 mAh battery supports 12–14 minutes per flight, fully recharging in 9 minutes using a 7,200 W charging station. This enables continuous operation with minimal downtime.

Ease of use for beginners

The intuitive touchscreen controller, Vietnamese-language interface, and auto-guided tutorials make the T50 easy to master after only 1–2 hours of training.


Maintenance and component lifespan

Maintenance cycle and part replacement costs

The T50 requires servicing every 300 flight hours. Annual replacement costs for parts (propellers, nozzles, bearings) range from 5–10 million VND. Following DJI’s maintenance guidelines extends drone lifespan to over 3 years.

Battery durability and charge cycles

Its smart lithium battery manages temperature and charge-discharge cycles safely for up to 1,000 recharge cycles, offering a 2-year average lifespan - significantly reducing replacement costs.

Technical support and software updates

DJI Vietnam regularly updates firmware, refining spray algorithms for different crops. Official warranty and software support ensure reliable long-term operation.


Overall assessment and investment recommendation

Key advantages of the T50

  • High productivity and precision spraying.
  • Efficient chemical and water use.
  • Strong, stable performance across all terrains.
  • Fast ROI and low operating cost per hectare.

Limitations to consider

The T50’s larger size requires wider takeoff zones, and its battery and charger costs are relatively high - factors to weigh in small-scale operations.

Who should invest in the T50

Best suited for cooperatives, service providers, and farms over 20 hectares. For smaller farms, renting drone services is more cost-effective.
