Abstract:
We have fabricated a new multimodal sensor chip that is capable of measuring water content and nutrient concentration on-site simultaneously. Heretofore in agriculture, water content sensors, for example the TDR sensor, could not provide water content information correctly, since the results of these sensors are affected by the nutrient concentration in the soil solution. Therefore, tensiometers have generally been used in agriculture. These are large-scale sensors and are not suitable for precision agriculture. Our proposed sensors are the world’s first to be able to monitor water content without being influenced by the nutrient concentration, and nutrient concentration without influence from the water content.
