Abstract

Correction for ‘Responses of CO2 and CH4 in the alpine wetlands of the Tibetan Plateau to warming and nitrogen and phosphorus additions’ by Wenbao Zhang et al.,Environ. Sci.: Processes Impacts, 2024, 26, 1516–1525, https://doi.org/10.1039/D4EM00174E.

The authors regret that there were errors in the Experimental design Section 2.2.1.

The corrected text and updated Table 1 in section 2.2.1 are shown below:

Table 1 Sample conditionsa

N P N P N P N P
a In the table, N and P represent the annual additions of nitrogen (g N per m per year) and phosphorus (g P per m2 per year) per plot, respectively.

Nitrogen and phosphorus addition treatments were applied at each temperature level, utilizing urea (CO(NH2)2) for nitrogen fertilization, with three gradients of nitrogen addition: N1 (5 g N per m2 per year), N2 (10 g N per m2 per year), and N3 (15 g N per m2 per year). Calcium dihydrogen phosphate (Ca(H2PO4)2) was employed for phosphorus fertilization, with three gradients of phosphorus addition: P1 (5 g P per m2 per year), P2 (10 g P per m2 per year), and P3 (15 g P per m2 per year). Additionally, a combined nitrogen and phosphorus treatment, N2P2 (10 g N per m2 per year, 10 g P per m2 per year), and a control (CK) with no nutrient additions were implemented, with the NW and no nutrient addition treatment serving as controls.
