The data collected by drones can help farmers detect early signs of disease or pest damage, allowing for targeted interventions. Drones are also being used to spray pesticides and fertilizers with high precision, reducing the need for manual labor and minimizing the environmental impact of over-spraying.

5. Automated Machinery

IoT-driven automation is taking over labour-intensive tasks on farms. **Autonomous tractors and harvesters** are equipped with sensors and GPS systems to perform activities like plowing, sowing, and harvesting without human intervention. These machines can work continuously and with high accuracy, reducing human errors and increasing operational efficiency.

For instance, automated machinery can be programmed to plant seeds in exact locations at the optimal depth, maximizing the chances of successful germination. Similarly, autonomous harvesters can work around the clock during peak seasons, ensuring that crops are harvested at the right time and in the best possible condition.

6. Predictive Analytics for Weather and Crop Forecasting

One of the most significant challenges for farmers is dealing with unpredictable weather patterns. IoT devices, combined with advanced data analytics, enable farmers to leverage predictive analytics for weather forecasting and crop management. Sensors track temperature, humidity, wind speed, and rainfall, providing farmers with detailed insights into upcoming weather conditions.
By using this data, farmers can anticipate challenges such as droughts, floods, or frosts and adjust their farming practices accordingly. Predictive models can also help in determining the best time to plant or harvest crops, reducing the risk of crop failure due to adverse weather.
