Abstract
Introduction
Material and methods
Results
Plant biomass and net ecosystem exchange
The NEE decreased significantly with increasing catch crop diversity (Fig. 1), suggesting increasing -C uptake from the atmosphere.
nullDiscussion
NEE is linked to plant diversity
... The NEE in our study showed a remarkably strong negative gradient from mustard to mix 4 to mix 12 (Fig. 1), which suggested higher photosynthetic -C fixation rates with increasing catch crop diversity.
