Wheat is one of the most important crops for global food security and a significant economic sector for the world's leading wheat producers, such as the European Union. One of the biggest threats to its production in the future will be a changing climate and increasing levels of pollutants, such as heavy metals, in agricultural soils. While there are reports on the individual effects of these two factors on the quantity and quality of wheat yields, it is still largely unknown if and how their combination will affect wheat productivity. Within my Ph.D. project, I want to determine threats to wheat production from climate change and metal pollution, and investigate what agricultural practices are most beneficial to minimize potential losses. For this purpose, I grow wheat under different climate, soil contamination and farming practice scenarios. In addition to determining wheat performance, I study microbial and geochemical patterns in the soil to indicate driving processes for metal distribution.
