Study examines future nitrogen needs for growing wheat: More wheat, more fertilizer?

In a recent article published in the journal Nature Plants, the authors used simulation experiments to show that nitrogen fertilization in wheat cultivation will have to increase up to fourfold in the coming years to exploit the yield potential of the varieties and feed the growing world population. However, this increased amount of nitrogen would have a negative impact on ecosystems in the agricultural landscape. Researchers from the Leibniz Centre for Agricultural Landscape Research (ZALF) were involved in the study.
