Abstract
Soil proximal sensing technologies provide an excellent opportunity for rationalizing input use. This paper critically reviews the current technologies available for soil and crop sensors and suggests effective, economically attractive alternatives for conventional methodologies. It also sheds light on the different types of sensors, including hand-held sensors and soil spectroscopy for precision agriculture. Additionally, this article explores options for drought monitoring and crop yield modelling through remote sensing. An overview of the Decision Support System (DSS), including ICAR Geoportal, is also presented to provide the real-time solution.
