Estonian scientists advance soil research with new scanning technology and digital mapping

Researchers in Estonia are utilizing new technologies to study and map the country's soil and underground ecosystems. University of Tartu scientists conducted a pilot project in the Järvselja forest, using waterproof containers to house scanners buried underground. These devices capture images at hourly intervals, allowing researchers to observe real-time biological rhythms, such as fungal growth, the movement of soil organisms, and water flow after rainfall, without destroying delicate root systems through excavation.

In a separate but related advancement, Estonian scientists have updated the nation's large-scale soil map for the first time in 50 years. This project has resulted in a modern digital data cube designed to facilitate faster analysis and international use of soil data. The new methodology and findings are being presented to highlight changes in Estonian soil composition and its implications for land use and agriculture.
