Paul-Tech Enhances Its Soil Stations with a Third Sensor

Paul-Tech’s science-based soil stations, designed to support farmers’ decision-making, will soon receive a significant upgrade with the introduction of a third sensor.

Paul-Tech continues to develop its science-based soil stations and the data platform that supports farmers. New stations, whose production began in December 2025, now include the option to add a third sensor, enabling the monitoring of soil water and nutrient dynamics at three different depths.

This enhancement provides farmers with an even more detailed real-time overview of how water and nutrients move through the soil profile, helping them better understand how fertilisation practices and weather conditions affect soil status and plant nutrition.

“Understanding how nutrient and soil water processes actually function is crucial in agriculture,” explains Tiit Plakk, Head of Science at Paul-Tech. “The third sensor allows us to observe changes across a wider soil profile and see how the upper, middle, and deeper soil layers interact. This helps farmers make even more precise, data-driven decisions and is particularly important as periods of drought and excessive rainfall become more frequent.”

According to Paul-Tech CEO Mikk Plakk, farmers using soil stations with two sensors do not need to worry about data sufficiency. “Two-sensor stations already provide a very good overview of water and nutrient dynamics within the crop root zone and strongly support day-to-day decision-making,” Plakk explains. “The third sensor is an additional option for those who want a deeper, scientifically validated understanding of whether and how nutrients move into deeper soil layers. Adding a third sensor is a natural step in Paul-Tech’s development and is offered to customers as an additional service.”

Paul-Tech is a science-based agricultural platform that enables farmers to make more accurate daily decisions using real-time soil data. The company’s soil sensors are developed based on multiple generations of scientific research and allow farmers to measure fertiliser efficiency in crop production and monitor soil water and nutrient movement processes in real time.
