In a landmark development for global agri-tech, UjuziKilimo, an Agri-Intelligence company, has unveiled SoilPal Pro, the world’s first smartphone-connected spectral soil sensor. The device brings laboratory-grade soil analysis directly to farmers’ hands, delivering instant, data-validated insights on soil health and transforming how soil intelligence is accessed and applied worldwide.
Reimagining Soil Intelligence
SoilPal Pro challenges the long-held belief that soil testing must be slow, costly, and centralized. By combining visible and near-infrared (VNIR) spectroscopy, AI-driven machine-learning analytics, and cloud connectivity, the sensor allows users to test soil on-site and receive actionable recommendations within seconds. What previously required complex laboratory logistics now happens instantly, turning soil data into a real-time decision-making tool for farmers, agribusinesses, and governments alike.
Each test analyzes over 13 critical soil parameters, including nitrogen, phosphorus, potassium, pH, organic carbon, moisture, and salinity. These results are processed through UjuziKilimo’s proprietary predictive agronomy engine, providing precise, localized recommendations directly to the user’s smartphone. The device works globally without local calibration, ensuring consistent accuracy across diverse agro-ecological zones and accelerating UjuziKilimo’s expansion into Europe, the United States, Asia, and South America.
“SoilPal Pro isn’t just about knowing your soil, it’s about democratizing access to soil intelligence,” said Brian Bosire, CEO of UjuziKilimo. “For farmers, enterprises, and governments alike, this innovation provides the clarity, speed, and scale required to transform agriculture in the face of rising input costs, climate pressures, and food security demands.”
Engineering Simplicity Without Compromise
Weighing just 105 grams, SoilPal Pro is designed for rugged, real-world environments. Every test connects to UjuziKilimo’s cloud-based platform, where AI models trained on thousands of soil profiles continuously adapt to local conditions. This enables large-scale applications ranging from enterprise-level input optimization and NGO-led sustainability programs to national agricultural dashboards and climate resilience initiatives.
Bosire emphasized the human perspective behind the innovation: “As a farmer’s son, I’ve seen firsthand the resilience it takes to turn uncertain soils into harvests. People growing our food deserve more than resilience; they deserve technology that is powerful, affordable, and tailored to the environments they farm in.”
Real-World Impact
Early users are already praising SoilPal Pro’s transformative potential. Maria Lopez, an organic vegetable gardener in New Jersey, USA, said: “Using SoilPal Pro for the first time was a game changer. In minutes, I had a full soil health profile on my phone—something that used to take weeks and hundreds of dollars. This technology doesn’t just save time; it gives me the confidence to invest wisely in my farm.”
The launch of SoilPal Pro also marks the retirement of SoilPal 1.0, which empowered over 100,000 farmers and delivered yield gains of up to 30% in the first season and 200% over three years, according to GSMA’s Mobile for Development report. With SoilPal Pro, UjuziKilimo introduces a commercially ready, globally scalable solution designed to serve diverse geographies and agricultural systems, ushering in a new era of accessible, actionable soil intelligence.
