Mission
CIEC (Centre International des Engrais Chimiques) is the oldest scientific organization solemnly dedicated to all issues of fertilizers and fertilization. CIEC was founded in 1932/1933 at the first International Scientific Conferences for Fertilizers in Rome and Amsterdam. CIEC is a non-profit, non-governmental organization (NGO) and actually organized as a task force with membership on invitation only. CIEC was merged with CIEC-ASIA (founded in 2016) in 2019. CIEC provides annual events to present and discuss scientific issues of fertilizer research and encourage international networking between stakeholders in science, industry, and politics.
