More and more technologies are being utilized to help modern agriculture be more productive and sustainable through soil health management with precision monitoring in real-time. Soil health indicators, including soil nutrients such as N, P, and K, and related properties like pH, electrical conductivity (EC), moisture, and water quality, can all be critical to crop yield, so their accurate measurements are crucial. Although traditional, lab-based soil tests can provide valuable information, sensor-enabled systems offer real-time and field-level monitoring, which means tests can happen much more quickly and at more timely intervals. This study will assess how fertilizer applications affect soil properties that are important to soil health in three different agro-ecological zones in Maharashtra: Alandi (Pune Division), Akola (Vidarbha Division), and Chhatrapati Sambhajinagar(Marathwada Division). In addition, this study incorporates systematic soil sampling and enhanced soil health indicators using IoT-enabled sensor technology to measure nutrient movement through time and across agro-ecological conditions. Finally, the study will also assess relationships between soil properties and crop response to provide an understanding of fertilizer practices. In general, outcomes and results will be used to formulate and give region-specific management recommendations and demonstrate how digital protocols can contribute to precision agriculture and long-term soil health sustainability.
