The amounts and dynamics of nitrogen transfer to grasses differ in alfalfa and white clover-based grass-legume mixtures as a result of rooting strategies and rhizodeposit quality

摘要

Differences in the ability to fix and transfer N have been shown between perennial legume species. However, the traits responsible for such variations are largely to be identified. This study aimed at comparing the dynamics of N transfer from alfalfa and white clover and test whether their differences resulted from difference in fixation, legume proportion, population dynamics or tissue composition.
