Soil degradation from excessive chemical fertilizer and lime use is a growing threat to sustainable agriculture, causing acidity, reduced productivity, and environmental harm. Our eco-friendly innovation addresses this through a natural soil pH stabilizer and nutrition restorer made from agricultural waste cow dung, yogurt, coconut husk, and eggshells formulated into a calcium-rich foliar spray. Integrated with an IoT-based automated system using Arduino UNO, moisture sensors, and a water pump, the solution optimizes application based on soil conditions. Field trials showed improved plant growth and reduced chemical reliance. Supporting SDGs 2, 12, and 13, this low-cost, scalable approach empowers small-scale farmers with smart, sustainable farming practices.
