Main subject area: Sensing; perennial grain crops; deep roots; modelling
Perennial grain crops such as intermediate wheatgrass (IWG) possess deep root system that are known to have a capacity to store greater amount of soil organic carbon (C) with roots as fresh litter and via rhizodeposition. However, little is known how dual-purposefully managed perennial grain crops alter their root growth and rhizodeposition following defoliation. Therefore, this master project aims at determining soil organic C dynamics by employing 13C pulse-labelling under dual-purpose IWG set up in field condition.
