Short summary
Zinc deficiency is a widespread nutritional problem in human populations, especially in sub-Saharan Africa (SSA). Crop Zn depends in part on soil Zn. The Zn status of soils from the Amahara region, Ethiopia, was quantified by measuring pseudo-total, available, soluble and isotopically exchangeable Zn, and soil geochemical properties were assessed. Widespread phyto-available Zn deficiency was observed. The results could be used to improve agronomic interventions to tackle Zn deficiency in SSA.
