作物生产力高度依赖于土壤中可溶性氮（N）的可用性，例如硝酸盐。当氮含量低时，施肥是为了补充土壤的储备。通常，这些应用的时间是基于基于纸张的指导和基于传感器的测量冠层绿度，这提供了一个间接的测量土壤氮的状态。然而，这种方法通常意味着氮肥施用不当或过晚，导致过量的氮流失到环境中，或者氮太少而不能满足作物需求。为了提高氮肥利用效率和提高农业可持续性，我们开发了一种物联网（IoT）方法，用于使用离子选择性膜传感器结合数字土壤水分探头实时测量土壤硝酸盐水平。该节点使用LoRaWAN收发器集成了最先进的物联网连接。传感平台可以通过云连接的网关传输实时数据，以进行处理和存储。总之，我们提出了一个经过验证的土壤传感器系统，用于实时监测土壤硝酸盐浓度，这可以支持施肥管理决策，提高氮素利用效率，减少氮素损失到环境中。
Crop productivity is highly dependent on the availability of soluble nitrogen (N), e.g. nitrate, in soil. When N levels are low, fertilisers are applied to replenish the soil’s reserves. Typically the timing of these applications is based on paper-based guidance and sensor-based measurements of canopy greenness, which provides an indirect measure of soil N status. However this approach often means that N fertiliser is applied inappropriately or too late, resulting in excess N being lost to the environment, or too little N to meet crop demand. To promote greater N use efficiency and improve agricultural sustainability, we developed an Internet of Things (IoT) approach for the real-time measurement of soil nitrate levels using ion-selective membrane sensors in combination with digital soil moisture probes. The node incorporates state-of-the-art IoT connectivity using a LoRaWAN transceiver. The sensing platform can transfer real-time data via a cloud-connected gateway for processing and storage. In summary, we present a validated soil sensor system for real-time monitoring of soil nitrate concentrations, which can support fertiliser management decisions, improve N use efficiency and reduce N losses to the environment.
