Edge computing in agriculture: Enhancing farming efficiency and sustainability

Agriculture, as one of the world’s oldest and most critical industries, has always been at the forefront of innovation to meet the growing demand for food, fiber, and fuel. In recent years, the integration of cutting-edge technology, specifically edge computing, has evolved the agricultural sector.

Edge computing refers to the practice of processing data closer to its source, for example, on or near the “edge” of the network, rather than relying solely on centralized data centers. This approach has the potential to reshape agriculture by improving efficiency, sustainability, and decision-making capabilities on farms.

Applications of edge computing in agriculture

Edge computing has made precision agriculture a reality. By deploying sensors and cameras in fields, farms can collect real-time data on soil conditions, weather, crop growth, and pest infestations. This data is processed locally, allowing for immediate adjustments in irrigation, fertilization, and pest control. Precision agriculture not only increases crop yields but also reduces resource wastage, making farming more sustainable.

Edge devices equipped with sensors can be used for monitoring livestock health and behavior. For example, wearable devices on cattle can provide early signs of illness or estrus, allowing farmers to take timely action. This enhances animal welfare, reduces mortality rates, and improves overall farm productivity.

Edge computing plays a pivotal role in enabling autonomous farming machinery. Tractors and drones equipped with edge devices can analyze field data in real-time, optimizing routes, adjusting planting depths, and even identifying and removing weeds without human intervention. This reduces labor costs and minimizes the use of chemical herbicides, making agriculture more eco-friendly.

According to a paper published by ResearchGate in 2019, two models of edge-enabled services may be considered – Node-centric services that act independently of the cloud and cloud-centric services that depend on at least one service from the Cloud for operation.

The paper notes that key benefits attributed to edge computing in agriculture include the reduction of latency, effective bandwidth utilization, and task off-loading are utilized to varying degrees. The status of edge computing in agriculture is dominated by physical edge servers coupled with local sensors and sensor networks.

Benefits of edge computing in agriculture

One of the primary advantages of edge computing in agriculture is reduced latency. By processing data at the edge, farmers have the ability to make instant decisions without waiting for data to travel to a remote data center and back. This is crucial for time-sensitive tasks such as irrigation, pest control, and equipment operation.

Venky Swaminathan, co-founder and CTO of Trilogy Networks tells EdgeIR: “It’s very critical for edge computing capabilities to be available in agriculture farming operations. All of the automation that is happening requires a massive amount of data to be processed very quickly for all the equipment to function.

“What is happening today is that much of the autonomy in agriculture is happening in onboard systems, which is not always scalable and makes it expensive. As a result, having edge computing capabilities will accelerate the autonomous process.”

Additionally, edge computing enhances data security by keeping sensitive information within the farm’s local network. This reduces the risk of data breaches and cyberattacks that could have devastating consequences in agriculture, where data often includes proprietary crop information, trade secrets, and financial data.

Agriculture often takes place in rural areas with limited internet connectivity. Edge computing minimizes the need for constant data transmission to centralized servers, thus optimizing bandwidth usage and ensuring that critical operations continue even in areas with poor network coverage.

Edge computing also promotes sustainable farming practices. By using real-time data to optimize resource usage, reduce waste, and minimize the environmental impact of agriculture, it contributes to the long-term viability of the industry.

“All of the sustainable farming practices involve capturing of real-time data – if you consider any type of regional data farming practices, those are the really early stages but nevertheless, they will require a lot of ground root (collecting data that is real and true from the ground). As the practises are being implemented and deployed you’ll have to be able to truly measure and evaluate those practises. The biggest challenge today is farmers are unsure of using more sustainable farming practices,” adds Swaminathan.

“Collecting the data and being able to transfer that into insights useful for farming and optimizing the resources used such as water and energy, all require a lot of data to be processed, would be possible without having robust edge computing capabilities to be able to process the data.”

Trilogy Networks is a digital agriculture platform that combines all this infrastructure, bringing together wireless networks, edge computing capabilities, and data management – all on a single platform called FarmGrid.

Swaminathan explains that the all-in-one solution allows the whole ecosystem of application developers to easily deploy their solutions, be it for measuring data from the ground, implementing sustainable farming practices or automation of equipment or controlling energy usage and carbon measurements.

Future prospects and challenges

While edge computing holds immense promise for agriculture, there are still some challenges that could be addressed to fully realize its potential.

The agricultural sector relies on a wide range of hardware and software systems from different vendors. Ensuring seamless interoperability between these systems is essential to harness the full benefits of edge computing.

Managing the vast amounts of data generated by edge devices can be overwhelming. Farms need robust data management solutions to store, process, and analyze this data effectively. Farmers and agricultural workers would, therefore, need to acquire the necessary skills to operate and maintain edge devices. Training and education initiatives are essential to bridge the skill gap.

“A lot of edge computing is already happening in precision agriculture for equipment today. For example, when a seed is planted into the field, the accurate location of that seed is captured in real time and processed in onboard systems that are in these seeding equipment,” adds Swaminathan.

“For spraying nutrients or fertilizers, you have application maps that show what to spray, where to spray and how much to spray. That is all processed on systems that are onboard.”

In remote rural areas, connectivity can be a significant challenge. Expanding internet access and improving network reliability are critical for the widespread adoption of edge computing in agriculture.

Protecting farm data from cyber threats and ensuring data privacy are paramount concerns. Implementing security measures is crucial to build trust in edge computing solutions.

The potential of edge

Edge computing is poised to transform agriculture by enabling precision farming, reducing resource wastage, and enhancing sustainability. Real-time data processing at the edge empowers farmers to make informed decisions, optimize operations, and increase productivity.

While challenges such as interoperability and data management must be addressed, the benefits of edge computing in agriculture are wide apparent.
