Tropical peatlands are unique and globally important ecosystems for carbon storage that are generally considered nutrient poor. However, different nutrient and trace element concentrations in these complex ecosystems and their interactions with carbon emissions are largely unknown. The objective of this research was to explore the concentrations of macro‐ and micronutrients and othertrace elements in surface peats, and their relationship with greenhouse gas emissions in North Selangor peatlands subjected to different land use. All nutrient and trace element concentrations except chromium exhibited significant differences between sites. Most macronutrients and some micronutrients showed significant differences between seasons, typically with a reduction over time from wet to dry seasons, possibly due to leaching. CO₂ emissions were positively related to organic matter content and manganese concentrations and negatively correlated with selenium. CH₄ emissions were positively correlated with organic matter content, manganese, copper, barium, cobalt and aluminium, and negatively correlated with molybdenum, selenium, lithium and vanadium. This research has detected loss of essential nutrients over time, aiding to increase nutrient limitation in tropical peatlands due to drainage. The observed significant correlation between trace elements and greenhouse gas emissions strengthens the importance of including trace element analyses in understanding the biogeochemical functions of these understudied peatlands.

营养和微量元素浓度影响马来西亚热带泥炭地的温室气体排放

热带泥炭地是碳储存的独特且全球重要的生态系统，通常被认为营养不良。但是，在这些复杂的生态系统中不同的养分和微量元素浓度及其与碳排放的相互作用在很大程度上是未知的。这项研究的目的是探讨受不同土地利用方式影响的北雪兰莪泥炭地表层泥炭中大量微量元素和微量元素的含量及其与温室气体排放的关系。除铬外，所有养分和痕量元素的浓度在位点之间均表现出显着差异。大多数常量营养素和一些微量营养素在不同季节之间表现出显着差异，通常从湿季到旱季随着时间的推移而减少，这可能是由于浸出造成的。一氧化碳₂排放与有机物含量和锰浓度成正相关，与硒成负相关。CH ₄排放与有机物含量，锰，铜，钡，钴和铝呈正相关，与钼，硒，锂和钒呈负相关。这项研究发现随着时间的流逝，必需养分流失，这有助于增加热带泥炭地由于排水造成的养分限制。观察到的微量元素与温室气体排放之间的显着相关性，增强了在理解这些被研究的泥炭地的生物地球化学功能中包括微量元素分析的重要性。
