7 practical applications of IoT in agriculture

Smart farming has evolved far beyond just a concept. Across the world, IoT technologies have taken root in virtually every area of agriculture:

Soil and Crop Monitoring

Through sensors monitoring soil moisture, nutrients, temperature and more, farmers gain deep visibility into soil and crop conditions. Beyond pinpointing issues faster, growers can use the data to forecast potential problems and apply preventative treatment.

Precision Farming and Input Management

Rather than applying uniform inputs (water, fertilizers, pesticides) across entire fields, precision farming and variable rate technology tailor inputs based on granular data and specific conditions on a plant, row or zone level. This radically reduces waste.

Livestock Monitoring and Management

From cattle and dairy tracking to poultry monitoring, IoT technology optimizes and simplifies livestock management. Smart ear tags, biometric wearables, video cameras and environmental sensors give deep insights into animal well-being, nutrition and development.

A Paraguay ranch deployed cattle trackers with motion sensors to monitor their free-range cattle’ locations and behaviors to detect abnormal issues like injury, falling, or theft.

Greenhouse and Indoor Ag Automation

Traditional greenhouses and emerging indoor vertical farms are becoming controlled environments automated by IoT. Every factor can be sensed and optimized – from climate control, supplemental lighting, hydroponic nutrients and beyond.

At a Dutch greenhouse facility, installing HVAC sensors and smart meter plugs trimmed energy costs by 50%.

Weather and Environmental Monitoring

Weather stations packed with smart sensors and connectivity enable up-to-the-minute micro-climate monitoring for crops. Data streams into platforms analyzing potential risks like frost, drought, rainfall and pest pressure to trigger real-time alerts for intervention.

Smart Irrigation and Water Management

With IoT water monitoring and smart irrigation systems, farmers can maintain ideal moisture levels while optimizing usage. Integrated weather data and soil sensors drive automated drip irrigation schedules customized by zone, crop and growth cycle.

Supply Chain Traceability and Visibility

Using the unique identities of connected IoT sensors and devices, agricultural companies can automatically log a digital trail tracking crops from the field to transportation, processing, distribution and retail. This boosts visibility and accountability across the supply chain.

IoT technologies powering smart agriculture

While smart agriculture involves many emerging technologies, IoT serves as the core foundation, incorporating and interconnecting tools like:
