On-the-go soil sensors have emerged as promising tools for real-time, high-resolution soil nutrient monitoring in precision agriculture. This review provides a comprehensive overview of the current state-of-the-art in on-the-go soil sensor technology, discussing the potential benefits, limitations, and applications of various sensor types, including optical sensors (Vis-NIR, MIR, ATR spectroscopy) and electrochemical sensors (ISEs, ISFETs). The integration of these sensors with positioning systems (GPS) enables the generation of detailed soil nutrient maps, which can guide site-specific management practices and optimize fertilizer application rates. However, factors such as soil moisture, texture, and heterogeneity can affect sensor performance, necessitating robust calibration models and standardized protocols. Future perspectives highlight the need for multi-sensor systems, incorporation into IoT networks for smart farming, and enhancing affordability and adoptability of on-the-go sensor technologies to promote widespread adoption in precision agriculture.
