**How A Startup’s Soil Moisture Sensor Predicts Drought Risk — And Why It Matters** In a time when precision agriculture and smart farming are reshaping how the U.S. monitors crop health, a growing focus lies on real-time environmental data — especially soil moisture. One emerging innovation combines satellite analytics, IoT sensors, and predictive algorithms to detect subtle shifts in soil conditions. Among these tools, a startup’s soil moisture sensor system stands out: it alerts farmers when moisture levels begin dropping at a steady rate of 2% per day. This seemingly simple observation raises a critical question: how long until that 100% baseline falls to 85%? This isn’t just a technical curiosity — it’s a reflection of broader concerns around water efficiency, drought resilience, and sustainable resource management. With climate patterns becoming more unpredictable, tools that anticipate soil stress before visible damage occurs are gaining real traction. The question gets to the heart of proactive farming: when—and how quickly—should irrigation or intervention begin? **Why This Topic Is Gaining Momentum in the U.S.**
