UnderGround Weather is building the world’s largest real-time underground intelligence network for nutrient management. Its Crophesy LS-N system continuously measures soil moisture, nitrate (NO3-N), oxidation-reduction potential (ORP), salinity, and temperature in real time, providing a direct view of nutrient availability and movement below ground. This IoT-enabled innovation helps agronomists and growers make more precise fertilizer decisions based on actual field conditions rather than assumptions.

In 2025, UnderGround Weather expanded large-scale deployments in collaboration with leading agricultural companies, agronomists, and input manufacturers across a diverse range of crops and geographies. These field programs generate continuous underground intelligence that supports evaluation of fertilizer practices, nutrient management strategies, and environmental outcomes under real-world growing conditions.

The company’s breakthrough nitrate and ORP data streams are now integrated into UnderGround Weather Reporter™, the world’s first AI soil intelligence reporting engine. The Physical AI Reporter transforms billions of underground measurements into field-specific insights, helping agronomists identify nutrient opportunities, understand soil conditions, and make more informed recommendations throughout the growing season.

With deployments across 16 countries, more than 130 dealers and large-scale growers, and nearly 1 million managed acres, UnderGround Weather has accumulated over 38 billion underground data points. This growing intelligence network spans row crops, specialty crops, and permanent crops across a wide range of climates and production systems.

UnderGround Weather helps the fertilizer industry move beyond estimates and periodic sampling by providing real-time underground intelligence that supports more effective nutrient management, improved nutrient use efficiency, and measurable sustainability outcomes.
