A significant amount of soil C can be captured by agricultural ecosystems through plant roots and harvest residues (humus formation). Crops characterised by large and deep root system such as sorghum (Sorghum bicolor L.), has high soil C input. Sorghum cultivation can contribute to improving soil organic C, therefore, climate protection. In Germany, the cultivation of sorghum is limited despite its suitability and competitiveness with other C4 crops such as maize. Moreover, sorghum cultivation in Germany is expected to increase under future climate scenarios of recurrent heat and drought events. In Germany, little is known about sorghum genotypes that are suitable for the local conditions. In this project, we will screen 10 sorghum hybrids for their biomass production and potential for C sequestration under drought stress in Braunschweig, Lower Saxony.
