Addressing the urgent need for sustainable agricultural practices in response to global population growth, this study introduces a sophisticated Soil Health Monitoring System and Land Management solution, powered by cloud server technology. This system integrates an array of IoT devices, including pH sensors, soil moisture sensors, DHT11 sensors for temperature and humidity, and NPK sensors, all connected through the NodeMCU ESP8266 microcontroller. These sensors continuously monitor essential soil parameters such as moisture content, pH levels, temperature, humidity, and nutrient levels of Nitrogen, Phosphorus, and Potassium. The data collected is relayed in real-time to a centralized cloud server, ensuring immediate data availability for analysis. An intuitive web application provides farmers access to up-to-date soil health data, enabling informed decision-making on nutrient management and irrigation practices. The system also delivers real-time alerts and advisory services, critical for timely interventions to prevent soil degradation and optimize crop productivity. Empirical results from the initial deployment demonstrate that continuous monitoring and real-time data analytics significantly improve crop productivity and resource use efficiency. These findings confirm that this system greatly enhances soil sustainability by providing precise, actionable insights that support the maintenance of soil health and promote efficient agricultural practices.
