Smart agriculture is revolutionizing crop production by integrating advanced technologies like the Internet of Things (IoT). One crucial aspect of smart agriculture is the efficient management of fertilizers, which optimize plant nutrition and increase crop yield. This paper proposes an automated low-cost IoT-based fertilizer intimation system to address the challenges faced by farmers in monitoring and managing fertilizer levels in their fields. The system uses IoT technology to collect real-time data on soil moisture, temperature, and nutrient levels, which are then transmitted to a central control unit using wireless communication protocols. The control unit processes the data and generates alerts and notifications to farmers regarding fertilizer requirements. The system is designed to be low-cost, accessible to small-scale farmers with limited resources, and scalable for deployment in larger farming areas or multiple fields. The benefits of the system include improved fertilizer management, reduced fertilizer wastage, increased crop yield, and minimized environmental impact. By leveraging IoT technology, farmers can make informed decisions regarding fertilizer application, leading to increased crop productivity and more sustainable farming practices.
