IoT technology is used in almost everything nowadays. The field of agriculture is no exception. It interconnects sensors and devices across a farm. Hence, the use of such knowledge proves effective in gathering real-time data on various aspects related to soil moisture, crop health, weather conditions, and other crucial parameters.
All this data and information helps agriculturalists make informed decisions regarding factors such as fertilization, irrigation, pest control, and harvesting, thereby enhancing their overall crop yield. This practice also reduces the expenditure on resources, thus mitigating environmental harm. It ensures smart farming by providing detailed insights through data analysis from the agrarian fields.
The Key Elements of IoT in Precision Agriculture
Here are some key elements of IoT in precision agriculture:
Sensors- Different types of sensors are placed across the ranches. It helps to perceive factors related to agrarian output like soil moisture, nutrient levels, light intensity, temperature, humidity, wind speed, and pH.
Data Collection and Transmission- The sensors accumulate information and send it wirelessly to a mother platform through numerous communication channels, such as cellular networks, LoRWAN, or NB-IoT.
Cloud Computing- This technical advancement makes working with information easy and from everywhere. Hence, the accumulated data is stowed and examined on cloud platforms, enabling access from anywhere and cutting-edge data processing.
Data Analytics and Decision Support System- Software algorithms process the data and create insights and recommendations for farmers regarding irrigation schedule, fertilizer application, pest control, and harvest schedule.
IoT is aimed at making decision-making easier for farmers, so they no longer have to depend on natural seasonal variations. They receive precise recommendations through data analytics that seldom cause any trouble for them.
Applications of IoT in Precision Agriculture
IoT has quite a few applications in precision agriculture that are mostly related to the key elements discussed above. The applications include:
- Smart Irrigation
- Variable Rate Application
- Crop Monitoring
- Weather Monitoring Stations
- Drone Imaging
- Livestock monitoring
Advantages of IoT in Precision Agriculture
IoT offers a compact, result-oriented solution to the agricultural sector. Thus, there are several advantages to using it optimally. They are:
- Increased Produce- Crop yield can be boosted by optimal resource allocation.
- Reduced Input Costs-Reducing unnecessary fertilizer and water usage can restrain the costs behind numerous resources, preserving them for future use.
- Enhanced Sustainability- Sustainability is enhanced by promoting environment-friendly farming practices, such as dipping chemical inputs into the crops.
- Improved Operational Efficiency- Streamline farm management through data-driven decision-making.
Challenges of IoT in Precision Agriculture
Like any other technologically progressive tool, the IoT in agriculture also has some drawbacks that can be worked upon. They are as follows:
- Network Coverage- It is a challenge to ensure connectivity in remote rural areas.
- Data Security- Protecting farm data from unauthorized access.
- High Initial Investment- The cost of implementing IoT mechanisms can be a significant burden to some farmers.
- Technical Expertise- Farmers lack the methodological knowledge to operate these systems. It is important to educate them on this.
Thus, the IoT for precision agriculture has advantages and disadvantages, but the system can be personalized, and farmers can be trained to enhance its effectiveness.
