Background and aims Few studies have investigated the effect of nitrogen (N) fertilizer on ecosystem respiration (Re) under mixed legume and grass pastures sown at different seeding ratios, and data are almost entirely lacking for alpine meadow of the Tibetan Plateau. Our aim was to test the hypothe...
