FOR IMMEDIATE RELEASE

UnderGround Weather combines direct underground measurement with AI-powered analysis to help growers and agronomists understand what is happening underground so they can make better decisions above ground.

SAN DIEGO, CA. — 4 August 2026— AquaSpy, an agtech company that builds continuous, multi-depth in-soil nitrate and moisture sensing, today announced it is rebranding as UnderGround Weather™ and launching a new category of soil intelligence, giving growers the same continuous visibility into conditions below the surface that they have long had above it.

Built on nearly two decades of underground sensing, UnderGround Weather replaces point-in-time soil sampling with a continuous, multi-depth view of the root zone — tracking nitrate and the other conditions that drive nutrient availability as they shift through the season.

Until now, agronomists have relied on a combination of soil sampling, field observations, weather data, and experience to understand what is happening below the surface. UnderGround Weather creates a continuous view of the underground environment, helping growers and advisors see how nutrients, moisture, oxygen, temperature, and biology change throughout the season.

“For nearly two decades, we’ve helped growers see what’s happening beneath their fields,” said Bruce Moeller, CEO. “Calling it UnderGround Weather names what we’ve long believed: the root zone has its own weather, and growers deserve to read it as clearly as they read the sky.” As part of the rebrand, the company also introduced UnderGround Weather Reporter™, the world’s first AI soil intelligence reporting engine.

UnderGround Weather Reporter automatically analyzes underground measurements, weather conditions, soil characteristics, crop activity, and management events to generate concise reports explaining what is happening in the root zone, why it matters, and what actions deserve attention.

UnderGround Weather is powered by Crophesy™ LS-N, which continuously measures nitrate, oxidation-reduction potential (ORP), moisture, salinity, and temperature throughout the root zone. These direct measurements provide the foundation for AI-powered interpretation and recommendations. This physical AI approach provides intelligence grounded in real, multi-depth measurement inside the soil rather than models or imagery alone.

“Most agricultural AI begins with assumptions and models,” Moeller said. “UnderGround Weather Reporter begins with direct measurement. First, we measure reality. Then AI helps explain what it means.”

The launch follows deployment of the technology across more than 900 nutrient management subscriptions spanning multiple crops, growing regions, and countries. UnderGround Weather is built on billions of underground measurements collected through nearly two decades of field experience.

The company believes the introduction of UnderGround Weather represents a shift from periodic soil monitoring toward continuous underground intelligence.

“Growers have weather reports. Agronomists have soil samples. What has been missing is a way to continuously understand how underground conditions are changing between those moments,” Moeller said. “That’s the gap UnderGround Weather is designed to fill.”

About UnderGround Weather™

UnderGround Weather™ combines direct underground measurement with AI-powered analysis to report what is happening underground so growers can make better decisions above ground. Built on nearly 20 years of underground sensing innovation from AquaSpy, the platform continuously measures nitrate, oxidation-reduction potential (ORP), moisture, salinity, and temperature throughout the crop root zone. By transforming billions of underground data points into real-time soil intelligence, UnderGround Weather helps growers, agronomists, retailers, and agricultural innovators improve nitrogen use efficiency, optimize irrigation, increase crop performance, and reduce environmental losses.

Results derived from grower yield responses and unique automated approach reveal new crop health insights

SAN DIEGO, CA 4 October 2022 – A new AquaSpy study is the agricultural industry’s first using yield correlated data to compare multiple variables across thousands of growing fields and different crop types. Study results reveal the relationship between optimum soil moisture, salinity, temperature, and crop health throughout the growing season. The findings reveal new insights into how to better manage the timing of farm inputs throughout the growing season for a number of different crop types including soybeans, corn, cotton, potato, sorghum and alfalfa.

“There has never been a study on a scale like this,” states Peter Ellegaard, AquaSpy CTO. “We are first in the world to look at thousands of fields with data normalized to compare one field to another.”

Why the AquaSpy study is different

There are several unique aspects to the AquaSpy yield correlation study. First, this study is based on yield responses that close the loop to prove efficacy. Growers provided relative yield results over thousands of different fields over a two-year period.

The second difference is that AquaSpy uses a layer-by-layer approach to look below the ground at the soil and the crop’s active and inactive root zones. This vertical approach to monitoring crop nutrient demand and health throughout the growing season differs from horizontal methods of only observing   the soil surface using drones, satellite, or single sensors, providing a view more in tune with actual root activity and specific crop needs at each and every growth stage throughout every day.

Data collected are relative measures which make it easier to normalize the data for true and accurate insights. AquaSpy intelligent technology delivers a picture of relative soil moisture and grower yield data results were reported in relative terms. All collection of the data is gathered and reported autonomously with no human intervention so it is scientifically pure. AgSpy intelligent algorithm analyzes and records relative inputs and crop consumption throughout the season, allowing AquaSpy data scientists to easily normalize the data for all the fields to Growing Degree Units (GDU’s). This aligns data for clearer analysis of trends.

Benefits of vertical insights into crops root zones

Having root-specific data literally avoids “spray and pray” – watering the field and hoping something good happens which leaves money on the table. AquaSpy takes this “horizontal” approach (spraying across the field) that assumes that since the soil is moist that it’s benefiting the roots, and flips that on its head with a vertical layer-by-layer approach looking deep into the crop root zone to a depth of up to 48 inches with sensors placed every 4 inches. Using this vertical approach of looking at each crop’s roots, a grower can gain up to 40% more yield in addition to conserving valuable water and costly nutrients. As this new study proves, the vertical approach lets the grower better control the timing and volume of irrigation as well as nutrients which leads to better crop health, consistency and yield.

How it differs from traditional university studies

This approach differs from traditional university studies where they can only deal with one variable at a time or use volumetric water measure. AquaSpy can look at multiple variables throughout the study. Rather than prescriptively anticipating and testing for a result, the plant signals its needs and conditions layer depth by layer depth, letting the data reveal the results.
