Trace elements history
From the 12th century to bolus inventionSince the 12th century, trace elements are central in numerous worldwide researches. Such as the observatories previously described, these studies relate to soils, crops and animals. In the same manner as what has been described for France, the main observatories relate to : soils or animals. The timelines below tell the historical findings made around the world and over centuries.
