| Abstract | In
addition to food quantity, food quality is paramount for meeting the
demands of a growing global population. Food quality encompasses both
nutritional and contaminant contents, yet their transfer within
soil-crop systems remains poorly understood under impending climate
change. This greenhouse study is the first to demonstrate that future
climatic conditions increase the transfer of metals from oxic soils to
crops, showcased for four soil-spinach variety combinations (Spinacia oleracea).
Future conditions raised harmful metal cadmium levels in edible spinach
tissues by 26–54%. In contrast, changes in micronutrient (Zn, Mn, Mg)
contents were inconsistent and dependent on the specific soil-spinach
combination. Climate-induced shifts in soil carbon composition and
bacterial communities were linked to greater soil Cd phytoavailability,
enhancing Cd transfer from soil to roots. These findings suggest that
while spinach's nutritional values may remain stable, future conditions
could lead to higher metal contaminants levels in edible tissues. |
