Water and soil efficiency through digital technology in Jerte Valley

This document presents a practical case study from the Jerte Valley in Extremadura, Spain, demonstrating how digitalization and sustainable agricultural practices improve water use efficiency and soil conservation. The R.E.M. Project (Efficient Mountain Irrigation), launched in 2021, integrates sensing technologies and innovative materials like porous vitreous aggregate (P03 and P310) to enhance soil water retention. On a pilot farm, 24 cherry trees were treated with these materials, applied in excavated holes near trunks, to reduce water and nutrient loss. The approach supports adaptive management, data-driven decision-making, and long-term agroecosystem resilience.
