Agriculture & IoT: How Connected Technology Transforms Modern Farming

January 26, 2026

Modern farmers face enormous challenges. Climate change leads to more frequent extreme weather events like droughts, late frosts, or heavy rain. At the same time, the world population is growing – projections estimate 9.7 billion people by 2050. And then there's the labor shortage in rural areas.

The Internet of Things (IoT) offers solutions to these problems. In this article, we show concrete use cases and real-world examples.

The Challenges of Modern Agriculture

Climate Change and Extreme Weather

Droughts, late frosts, heavy rain – harvests become unpredictable. Farmers need early warning systems and the ability to react quickly.

Resource Scarcity

Water must be used more efficiently, fertilizer and pesticide use must be reduced. Rising operating costs for fuel and fertilizer put pressure on margins.

Labor Shortage

Fewer and fewer people work in agriculture. Automation is no longer an option – it's becoming a necessity.

How IoT Solves These Problems

Connected sensors and devices enable data-driven agriculture. Information is collected and analyzed in real-time – from soil temperature and moisture to weather data to livestock health.

The Benefits:

  • Informed decisions through transparent data
  • Automated processes – irrigation starts automatically during drought
  • Resource efficiency – water and fertilizer only where needed
  • Early warning systems – detect risks before damage occurs
  • Mechanization – compensate for labor shortages

Concrete Use Cases

1. Soil Moisture Monitoring & Smart Irrigation

IoT sensors in the field continuously measure soil moisture. This real-time data enables demand-based irrigation: plants receive exactly the right amount of water at the right time.

Result: Less water waste, no drought stress, higher yields.

2. Greenhouse Climate Control

In smart greenhouses, networked sensors and actuators automatically regulate:

  • Temperature
  • Humidity
  • Irrigation
  • Lighting

This maintains optimal growing conditions at all times – with lower energy consumption and less manual effort.

3. Livestock Tracking & Animal Health

Wearables like collars or ear tags capture:

  • Location (GPS tracking)
  • Activity and feeding behavior
  • Body temperature

Anomalies are automatically reported to the farmer. Diseases or injuries can be detected early.

4. Fertilizer Optimization

Soil sensors, weather stations, and drones analyze:

  • Soil quality and nutrient content
  • Plant health
  • Pest infestation

The system determines exactly where and when fertilizer or pesticides are needed – and where not. This saves resources and protects the environment.

5. Predictive Maintenance for Farm Equipment

Modern tractors, combine harvesters, and milking robots continuously deliver telemetry data. The system detects maintenance needs or wear before a breakdown in the field.

Result: Timely repairs, no expensive machine failures during harvest.

Real-World Examples

Agvolution & Vodafone (Germany)

In Rhineland-Palatinate, over 100 networked sensors protect around 13,500 hectares of farmland from weather damage. An AI-powered system alerts farmers via app to late frost or drought and recommends targeted irrigation measures.

AGCO Fendt (Europe)

The farm equipment manufacturer connects tractors and harvesters with farmers' farm management software. Job data, guidance data, and machine data are seamlessly exchanged – saving work time and enabling optimized application of resources.

Philips City Farming (Netherlands)

In container greenhouses, sensors and LED lighting fully automatically regulate growth. The result: up to 20x yield per square meter with 90% less water consumption through closed water cycles.

Landwirt Center: Digitalization in Agriculture

Keners Smart Farming (Czech Republic)

The company uses ThingsBoard to centrally process data from fields, greenhouses, and the environment. Soil sensors, weather stations, and devices are monitored and controlled via customized dashboards.

The Right Technology: LoRaWAN for Agriculture

LoRaWAN has established itself as the ideal wireless technology for agricultural IoT applications:

  • Long range – up to 15 km in open field
  • Low cost – inexpensive sensors and no cellular contract needed
  • Long battery life – 5-10 years without battery replacement
  • Good penetration – works even in barns, cellars, and silos
