Types of Drones Used in Agriculture
Drones in agriculture use are not a one-size-fits-all solution when it comes to agriculture. Different types of drones are available, each tailored to specific functions and farming needs. Understanding the varieties of drones used in agriculture is crucial to harnessing their full potential and optimizing farm operations. Several drone designs each offer certain advantages:
Fixed-Wing Drones
Fixed-wing drones resemble small aircraft with longer flight times of up to 45 minutes and a range of up to 15 km enabled by forward airfoil-driven lift. However, they require space for runway takeoffs and landings. They are often the choice for larger agricultural operations, such as expansive crop fields and vast orchards. Their efficiency in covering extensive terrain minimizes the need for frequent take-offs and landings, saving both time and energy.
Multi-Rotor Drones
Multi-rotor drones use four to eight propeller arms for vertical takeoff and landing, eliminating runway needs. However, the average flight duration is 15-25 minutes due to battery-powered hovering. Their key advantage lies in their stability and maneuverability. Multi-rotor drones can hover in place, providing a steady platform for capturing high-resolution images and collecting detailed data. Multi-rotor drones are well-suited for scenarios where detailed, up-close assessments of crops are essential. They can easily navigate around obstacles, such as trees or buildings, ensuring that no part of the field is overlooked.
Hybrid Drones
Hybrid drones combine features of both fixed-wing and multi-rotor drones, offering a versatile solution for various agricultural applications. They’re designed to provide the benefits of vertical take-off and landing, similar to multi-rotor drones, while also offering the efficiency and extended range of fixed-wing drones. This adaptability is particularly advantageous in scenarios where a combination of functions is required. For instance, hybrid drones can perform tasks that demand close inspection of crops, such as checking for pests or diseases, and then swiftly transition to covering more substantial areas for general monitoring. Their unique design allows for flexibility in handling diverse agricultural needs, making them a valuable tool for farmers who require a versatile and adaptable solution.
Each type of drone has its place in agriculture, offering specific advantages tailored to the requirements of different farming operations. The choice of drone depends on factors such as the size of the farm, the type of crops, the need for precision, and the specific tasks at hand. By understanding the characteristics of these drones, farmers can make informed decisions on which type is best suited to optimize their agricultural practices and achieve the desired results.
Real-Time Crop Monitoring
Drones in agriculture imagery and sensors provide invaluable aerial views of crop health and development:
High-resolution RGB cameras detect growth variations, irrigation issues, and pest damage across fields through photogrammetry models and change detection in time-series imagery. Multispectral sensors analyze plant stress indicators and health metrics like chlorophyll levels that manifest before anomalies are visible to the naked human eye. This facilitates early-stage disease and infestation detection for preventative treatment.
Tracking disease progression across growth stages via repeat drone monitoring informs models for optimal harvest timing to maximize crop value. Onboard image processing can even enable real-time in-field scouting to identify needs for precision treatment application as the drone passes over crops.
The detailed vegetative index maps generated from drone imagery also enable estimating yield forecasts and maturity timelines much more accurately than manual ground inspection. Overall, these capabilities empower timely data-driven crop management.
Data Collection and Analysis
Key analytics transform raw drones in agriculture data into actionable insights:
Photogrammetry processing generates detailed 3D terrain models, crop surface maps, and volumetric biomass models from drone imagery. Combined with time series animations, these maps provide invaluable geometric insights surrounding crop growth and topography factors.
Machine learning classifiers like convolutional neural networks can be trained using annotated drone imagery to categorize crop conditions, detect diseases, map weeds, and much more. This automation helps scale analysis.
Cloud computing accelerates image processing pipelines to handle large drone-collected datasets spanning thousands of high-resolution photographs per flight.
Geographic information systems help integrate spatial insights across entire fields and the whole farm enterprise. Clean software dashboards can present analytics clearly for growers to interpret and act on effectively.
Targeted Application and Treatment
Drones in agriculture enable ultra-precise intervention applications:
Targeted Spraying
Multi-spectral crop imaging helps target pesticide spraying very precisely onto infected plants rather than uniform blanket spraying of entire fields. This guides treatment only where needed, reducing pesticide usage by over 75% compared to traditional practices.
Determining Soil Deficiencies
Micronutrient deficiencies determined by soil variability maps can be addressed via specific foliar treatments guided by modeling drone imagery showing locations in need of supplementation for each element.
Minimizing Herbicide Usage
Intelligent weed control results from using drone height maps to strategically adjust sprayer heights and droplet sizes to match variable weed stands. This minimizes herbicide usage through precise weed-specific application.
Uniform Coverage
For broad spraying applications, AI swarm control of autonomous drones allows leveraging real-time wind data to adapt optimal flight paths and spacing between vehicles to achieve required coverage uniformity. Inter-drone collision avoidance prevents problematic gaps in application.
Drone use cases in agriculture:
Scouting/Monitoring Plant Health: One of the drone use cases in agriculture is to monitor the health of plants. Drones equipped with special imaging equipment use accurate color information to indicate plant health. This allows farmers to monitor crops as they grow so any problems can be dealt with quickly to save the plants.
Drones that use conventional cameras are also used to monitor crop health. Most farmers use satellite images to monitor crop growth, density and coloration, but accessing satellite data is expensive and in most cases not as effective as drone imagery. Because drones fly close to fields, cloud cover and poor light conditions are less important than when using satellite imagery. Satellite imaging may provide meter accuracy, but drone imaging can provide accurate locations down to millimeters, meaning that after planting, areas with base gaps can be identified and replanted if needed. Disease or pest problems can also be identified and treated immediately.
Monitoring Field Conditions: Drone field monitoring is also used to monitor soil health and farm conditions. Drones can provide detailed mapping of the field, including elevation information, allowing farmers to locate any irregularities in the field. Having information about field elevation is useful in determining drainage patterns and wet or dry spots that allow for more effective irrigation techniques. Some vendors and service providers of agricultural drones also offer soil nitrogen level monitoring using more advanced sensors. This ability to accurately use fertilizers, remove weak spots, provides growth and improved soil health for years to come.
Planting seeds: One of the newer drone use cases in agriculture is to plant straw seeds. Automatic drone planting is currently mostly used in the forestry industry, but it has the potential for more use. Planting with unmanned drones means that very difficult crops can be replanted without endangering workers.
Identifying weeds: Drones can be used to identify weeds in the field, this is the other drone use cases in agriculture. These weeds can be eliminated in the field so that they do not compete for resources with the main crop.
Crop spraying: Drones can be used to spray chemicals including fertilizers, pesticides, and other items based on the spatial diversity of crops and fields, it’s one of the best drone use cases in agriculture. According to the conditions of the product or the intensity of the attack of pest insects, the amount of chemicals can be adjusted. In this way, drones facilitate the path of precision agriculture. This will ultimately increase the efficiency of the chemicals used, thus reducing soil and water pollution, and their adverse effects on the environment will be reduced. As a result, it can lead to sustainable agriculture. Drones spray chemicals faster than other methods. They can also lead to savings in the amount of chemicals used, which reduces input costs. There is a problem of unbalance of tractor machinery when spraying chemicals on long crops, which can sometimes cause accidents. As a result, spraying chemicals on tall crops can be done with the help of drones without any damage.
Managing excess crop residues in the field is another common problem that farmers face. Removing these plant residues from fields is costly and time-consuming, as a result, farmers are willing to burn them, thus leading to environmental pollution and soil health destruction. These residues can be effectively and cost-effectively managed by spraying plant residue-degrading microbial formulations in the field. This process can be done effectively by drones, which can maintain soil quality and prevent environmental pollution.
