Innovative Sensor Solutions for Soilless Cultivation of High-Value Vegetable Crops

Abstract

Environmental and nutritional parameters are travelling towards innovation. Sensor-based soilless vegetable cultivation is revolutionising the entire industry by providing high-level control and monitoring over important environmental and nutritional factors. These sensors are critical in the optimal conditions of growth, increased yield of crops, and effective utilisation of resources in the hydroponic, aeroponic, and aquaponic systems. To provide the best environment to sustain a healthy growing condition, the sensors on the environment track the temperature, humidity, light and CO 2 level, whereas the nutrient and water management sensors regulate the optimum pH, electrical conductivity, dissolved oxygen level, and flow rate. Sensor-based substrate In soilless substrates, moisture and salinity sensors are used to avoid overwatering and salt accumulation. Real-time data is collected, and predictive adjustments and remote monitoring can be done with the help of an automated control system and IoT integration, which further adds to precision farming. Sensors such as multispectral imaging and infrared sensors are pest and disease detection sensors which give early signals before any problem occurs and hence quick solutions are possible then. Use of such sensors results in better yields, lesser wastage of resources and greater sustainability, which makes soilless farming an efficient and feasible agricultural practice in high valued vegetable crops. Enhanced sensor technology and AI integration will further ensure increased accuracy and efficiency, which is likely to keep modern agriculture resilient and sustainable.
