State-of-the-Art Review of the Impact of Climatic Change on Bioavailability of Mineral Elements in Crops

We critically review the current state of understanding of how bioaccumulation and bioavailability of trace elements in crops might be affected by global warming and elevated CO[sub 2] concentrations, and the interaction of different environmental processes in controlling the transfer, distribution and deposition of mineral elements in crops in a changing environment. While bioaccumulation of mineral elements in crops is recognized as a physiologically important process, and is affected by several different climate variables, we know little about how these variables interact with other climate variables affecting plant productivity, and how mineral stresses at the individual plant level translate to impacts at the agroecosystem level. There is clear need to integrate our current understanding from quantitative experimental studies within process-based models of plant productivity that should include interactions among climate, mineral stress and herbivory in order to better predict the responses of crops and pastures to future global climate change. This paper talks about the state-of-the-art review of the impact of climatic change on bioavailability of mineral elements in crops.
