Abstract:BackgroundCrop‐ and site‐specific quantification of non‐harvestable aboveground residues and root biomass is essential for predicting management‐induced changes in soil C storage.AimsThe aim of this study was to quantify stubble and root biomass C from productive grass–clover leys used for cutting as affected by fertilization and sward age.MethodsBased on an organic long‐term dairy crop rotations experiment with 4 years of grass–clover in a six‐course rotation, we examined the effects of fertilization (unferti… Show more
