Arsenic pollution in paddy fields has become a public concern by seriously threatening rice
growth, food security and human health. In this review, we delve into the biogeochemical …

Microbial communities play critical roles in fixing carbon from the atmosphere and fixing it in
the soils. However, the large‐scale variations and drivers of these microbial communities …

The frequently occurring redox fluctuations in paddy soil are critical to the cycling of redox-
sensitive elements (eg, iron (Fe) and carbon) due to the driving of microbial processes …

Periodic redox condition changes in acidic paddy soils substantially induce the
biogeochemical redox cycling, and consequently affect Cd availability. However, the …

Soil cadmium (Cd) contamination is becoming a widespread concern because of its threat to
global ecosystem health and food security. Co-incorporation of Chinese milk vetch (MV) and …

Carbon fixation is a critical process for our planet; however, its distribution across the
bacterial and archaeal domains of life has not been comprehensively studied. Here, we …

The incorporation of secondary metal atoms into iron oxyhydroxides may regulate the
surface chemistry of mediating electron transfer (ET) and, therefore, the biogeochemical …

Dissolved organic matter (DOM) play critical roles in arsenic (As) biotransformation in
groundwater, but its compositional characteristics and interactions with indigenous microbial …

Soil is a key carbon reservoir balancing global carbon budget and regulating climate
change. Barren soils in karst zones have weak capacity for soil and water conservation and …

Microbially mediated Fe (II) oxidation is prevalent and thought to be central to many
biogeochemical processes in paddy soils. However, we have limited insights into the Fe (II) …
