This GLOSOLAN video, presented by the Global Soil Partnership and FAO, details a standardized method for determining micronutrients and heavy metals in soils using DTPA extraction. Supported by AGROSAVIA, it covers key stages from representative sampling and pretreatment to instrumental analysis via techniques like FAAS, ETAAS, and ICP-OES.

The method highlights essential micronutrients (Cu, Fe, Mn, Zn) crucial for plant development, alongside the risks of potentially toxic metals (Cd, Pb, Ni). Emphasizing harmonized protocols, quality control, and constant monitoring ensures reliable results, supporting sustainable soil management, human health, and food security.
