The editorial office would like to draw reader's attention to an error occurring in the publication by Dreyer et al. · Ammonium‐driven nitrification plays a key role in increasing Mn availability in calcareous soils · pp. 389–396 · Volume 183 · Number 3 · June 2020 that we like to apologize for.

1. Figure 2 :

The correct figure caption is:

“Impact of stabilized and non‐stabilized N fertilizer on Mn concentration aboveground plant material at EC 31 (Pot Experiment I). Different letters indicate significant differences between treatments; Duncan‐test (α = 5%). Error bars indicate the standard deviation (n = 5). CN = calcium nitrate, AN = ammonium nitrate, AS = ammonium sulfate, ATS = ammonium thiosulfate, DCD = Dicyandiamid.”

正确的图形标题为：

“稳定和不稳定的氮肥对EC 31地上植物材料中锰浓度的影响（盆栽试验I）。不同的字母表示治疗之间的显着差异。邓肯检验（α= 5％）。误差棒表示标准偏差（n = 5）。CN =硝酸钙，AN =硝酸铵，AS =硫酸铵，ATS =硫代硫酸铵，DCD =双氰胺。”
