[Short-term nitrogen deposition changes chemical composition of litter and soil organic matter in a Moso bamboo forest].

To investigate the effects of short-term nitrogen (N) deposition on organic matter composition of litter and soil in Moso bamboo () forests, we established a N-addition treatments (50 kg N·hm·a) to simulate the ambient and N deposition in a subtropical Moso bamboo forest from July 2020 to January 2022. We analyzed the organic matter composition of Moso bamboo leaf/root litter and soil by using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) technique. The results showed that short-term N deposition significantly increased the relative content of soil phenols by 50.
