在未来30年，预计世界将需要增加70%的粮食来满足不断增长的人口，其中很可能有相当大一部分将来自灌溉土地。然而，灌溉水的质量也很重要，测量这些水的质量将有助于做出管理决策。土壤盐分是农作物产量的重要参数，在本文中，我们描述了一个氯离子传感器系统的基础上，低成本的鲁棒性丝网印刷氯离子传感器，适用于分布式传感器网络。以前，这种传感器已被用于控制实验室为基础的实验，但在这里，我们提供的证据表明，该传感器将在实验室外的现场部署中找到应用。我们报告三个实验，使用这种传感器，一个土柱，一个使用fluvarium，最后在温室实验。所有这些都提供了一个洞察氯化物的运动在小距离与高时间分辨率。这些初步实验表明，新的传感器是可行的，可以用相对简单的电子设备使用，虽然仍在不断发展，但它们目前能够以高空间和时间分辨率提供新的科学数据。因此，我们的结论是，这样的氯离子传感器，再加上分布式无线网络，提供了一个新的模式，在水文监测，并将使新的应用，如灌溉使用的混合饮用水和微咸水，具有显着的成本和资源节约。
Over the next 30 years, it is anticipated that the world will need to source 70% more food to provide for the growing population, and it is likely that a significant amount of this will have to come from irrigated land. However, the quality of irrigation water is also important, and measuring the quality of this water will allow management decisions to be made. Soil salinity is an important parameter in crop yield, and in this paper, we describe a chloride sensor system based on a low-cost robust screen-printed chloride ion sensor, suitable for use in distributed sensor networks. Previously, this sensor has been used in controlled laboratory-based experiments, but here we provide evidence that the sensor will find application outside of the laboratory in field deployments. We report on three experiments using this sensor; one with a soil column, one using a fluvarium, and finally on an experiment in a greenhouse. All these give an insight into the movement of chloride over small distances with high temporal resolution. These initial experiments illustrate that the new sensors are viable and usable with relatively simple electronics, and although subject to ongoing development, they are currently capable of providing new scientific data at high spatial and temporal resolutions. Therefore, we conclude that such chloride sensors, coupled with a distributed wireless network, offer a new paradigm in hydrological monitoring and will enable new applications, such as irrigation using mixtures of potable and brackish water, with significant cost and resource saving.
