This article uses experimental archaeology to provide empirical data on the impact of soil salinization on ancient maize agriculture. Hopi blue maize was experimentally grown in a drought-prone soil containing an extremely high level (50%) of evaporite mineral salts (CaCO 3 , CaSO 4 , and NaCl) in order to evaluate their effect on agricultural productivity. A control group of plants was grown in the absence of mineral salts. All of plants, which were companion planted with beans and squash, were adversely impacted by evaporite mineral salts. Maize grown alone in CaCO 3 −, CaSO 4 −, and NaCl-enriched soil exceeded the height of the control plants because the mineral salts acted as a fertilizer. Plants grown in NaCl-enriched soil produced cobbs that were reduced in size and kernel number. These findings suggest that CaCO 3 and CaSO 4 , the most common evaporite mineral salts found in soil, would not have adversely impacted Ancestral Puebloan maize agriculture
