Techniques for monitoring crop mineral requirements in the Mediterranean

NATAE Practice abstract n. 9: Efficiency. Working Package 7. A NATAE practice abstract is a summary that describes an agroecological practice that can be used as a valuable resource by farmers, researchers, policy makers, and other stakeholders interested in adopting or promoting agricultural practices that contribute to sustainability, productivity, and competitiveness in the agricultural sector. This document explores techniques for monitoring crop mineral requirements in Mediterranean agroecological systems. It highlights classic methods like laboratory soil analysis, visual plant observation, and leaf sampling, as well as recent innovations such as soil sensors, proximal spectrometry, and remote sensing. These tools help optimize nutrient use, reduce chemical inputs, and preserve soil fertility. Challenges include the need for well-equipped labs, localized standards, and robust databases for accurate interpretation. The goal is to build sustainable soil fertility through integrated nutrient management, enhancing soil structure and biological health.
