About Digital Agriculture
Digital devices put data from our fields and facilities at our fingertips. Only by harnessing data’s power — and training others to do the same — can it create a sustainable agricultural future. At Purdue University, digital agriculture and data science leverages increasingly innovative technology with our world-renowned know-how to improve agricultural efficiency, productivity and sustainability.
What is digital agriculture?
It’s the use of digital devices to gather, process and analyze spatial (object) or temporal (time) data. This data can then guide targeted actions to improve agricultural efficiency, productivity and sustainability.
Purdue Agriculture’s vision is to be a global leader in:
- Digital science and agriculture education to prepare our students for what’s next
- Outreach / training to empower producers and stakeholders
- Applying data standards, analytics and management to decision-making
The Purdue advancement of Digital Agriculture involves fusing our physical and social worlds using modern data-intensive technologies to collect, connect, curate, communicate, and compute. As we integrate characterization and modeling, we improve decision making and even autonomous action.Data Science for Agriculture
Our faculty and students apply and develop techniques for turning data into insights - even unassisted action - through artificial intelligence, visualization, and virtual models of physical, biological, chemical and social phenomena.Closing the digital divide
The region has several initiatives to develop and deploy advanced technologies to improve connectivity of internet of things (IoT) devices for agriculture as well as improve quality of life in rural communities.UAV / remote sensing
Through research and outreach, unmanned vehicles are being used in a variety of applications including hyperspectral imaging, high-throughput phenotyping, livestock management, and logistics improvement.Testbeds for next-gen technology for agriculture
Purdue research farms are fully-connected for in-field research; they have high-capacity multi-band connectivity and a high speed data pipeline for testing IoT systems featuring autonomous data.Education/workforce development efforts
A combination of extension programs, undergraduate and graduate courses and certificates are designed to meet hi-tech and data-science-for-agriculture needs.Farmer network
Through the Wabash Heartland Innovation Network, we have an alliance of progressive farmers teaming to test technology and feed analytic systems for improved decision making.Ongoing innovation
The ecosystem of converging technologies and disciplines is generating a culture of collaboration among researchers and educators to facilitate rapid innovation to work toward lasting global impact.
Areas of Focus
Enhancing the production efficiency, quality and safety of meat, milk, fiber, and other animal products can be greatly enhanced by employing digital technologies. Sensors on animals can enhance decisions related to managing animal health, improving comfort, and increasing production. Automation can help streamline repetitive processes and accomplish difficult tasks, saving costs and helping to reduce human error. Added insights of sensors, including image and video, can offer tailored intervention otherwise impractical in large-scale operations.
Using robotic operations to accomplish repetitive or difficult tasks in biological systems can reduce production expenses, enhance consistency, and free humans to accomplish other duties. Examples include machine weeding around plants, robotic milking of dairy cows, robots that harvest nuts, fruits, and vegetables, or automation of implement control such as section controllers on sprayers, boom height, tillage implement depth, combine threshing/cleaning settings, and navigation.
As sensor data becomes more available and our ability to store and move data increases, our need to manage and extract insights from data increases.
We are turning data into insights – even unassisted action – through artificial intelligence, visualization, and virtual models of physical, biological, chemical and social phenomena. But collecting, moving, managing, visualizing, analyzing, and interpreting data from disparate systems has significant technical as well as social challenges.
Researchers are working towards developing platforms and strategies that leverage digital technology to measure, monitor and manage urban and rural forests to maximize social, economic and ecological benefits. At Purdue University the Integrated Digital Forestry Initiative (IDiF) brings together a multidisciplinary research team to revolutionize forestry with an effective digital system for precision forest management and build a globally competitive next generation workforce for the information age.

For digital agriculture to be successful, it must be economically viable, and be environmentally and socially sustainable as well. In addition, digital technologies can enable new impacts well beyond production environments, such as product traceability and enabling environmental incentives. As digital agriculture encompasses a related set of technologies that are often used differently depending on the region and production environment, it is difficult to make general statements about the economics or reasons for adopting digital agriculture.
Field crop production has been a leading area for digital agriculture in many places around the world, due in part to large scale and mechanization. Machine guidance and site-specific input application is commonplace. Natural variations in soil characteristics, spatially and temporally managing water, nutrients, and pesticides offer great opportunities to add value. Automation is poised to change production environments in the coming years.
All humans have a connection to agriculture through the food chain. Sensors and systems from harvest through consumption help to improve quality and safety. Added value can come through identity preservation (traceability) and associated marketing which relies on accurate trait, transport, and processing records. Post-harvest systems in developing countries are particularly in need of improvement.
Plant breeders, engineers, computer scientists, and aviation scientists are collaborating in a space that impacts our entire food production system – the field. Once laborious and time-consuming processes are now automated for measuring characteristics such as plant height, nitrogen content, and photosynthetic activity. The process of measuring and analyzing observable plant characteristics, phenotyping, allows researchers to observe and measure from remote sensors in the air and on the ground under variable environmental conditions. Understanding this variation will help farmers and plant breeders grow better crops regardless of the environment, and allow researchers to more quickly identify how and why genes are expressed.
Sensors that can quantify factors related to crop, animal, and woodland production and environmental management are the foundations of digital management. When those sensors are interconnected and communicate in real time, that concept is Internet of Things, or IoT. Sensors can be mounted on satellites, airplanes, unmanned aerial vehicles or drones, ground-driven implements, or in fixed or semi-fixed locations on plants or animals or in the soil. Common measurements include geographic coordinates, electromagnetic reflectance within the visible, near infrared, thermal, and other spectrums, temperature, pressure, speed, resistance, vibration, and humidity.
The economic and societal importance of vegetables, tree fruits and nuts, berries, grapes, nursery and greenhouse production, as well as specialty grains and oilseeds offers boundless opportunities for implementing digital agriculture. Challenges include the many unique production environments that characterize specialty crop production, the critical importance of product quality and time sensitivity of many operations.
