The integration of fertigation with sensor-based technologies is a revolutionary approach in modern agriculture, addressing critical challenges related to water scarcity, nutrient management and sustainable farming. Fertigation, which combines irrigation and fertilization, optimizes nutrient delivery directly to plant roots, reducing wastage and improving crop productivity. Sensor-based technologies enhance this process by providing real-time data on soil moisture, temperature, electrical conductivity (EC) and nutrient levels, enabling precise and automated control over fertigation systems. The adoption of automated and semi-automated fertigation solutions, supported by Internet of Things (IoT) and artificial intelligence (AI), allows for efficient resource utilization, cost reduction and improved crop yields. This article explores the components, benefits and challenges of sensor-based fertigation systems. Additionally, prospects, such as nano-sensors, selfpowered wireless sensors and advanced fertigation software, are discussed to illustrate the potential of this technology in transforming global agriculture.
