Dynamic variation of dissolved As, Sb, Fe and S in paddy soil triggered by nitrate loading to overlaying water
Arsenic (As) and antimony (Sb) are toxic elements that usually co-occur in paddy soils due to their chemical similarity. Those elements are redox-sensitive and shift their species across the soil–water interfa...

Open AccessMicrobial mechanisms of organic matter mineralization induced by straw in biochar-amended paddy soil
Combined straw and straw-derived biochar input is commonly applied by farmland management in low-fertility soils. Although straw return increases soil organic matter (SOM) contents, it also primes SOM minerali...

Microplastics affect activity and spatial distribution of C, N, and P hydrolases in rice rhizosphere
Microplastics provide a new ecological niche for microorganisms, and the accumulation levels of microplastics (MPs) in terrestrial ecosystems are higher than those in marine ecosystems. Here, we applied the zy...

Legacy effect of elevated CO2 and N fertilization on mineralization and retention of rice (Oryza sativa L.) rhizodeposit-C in paddy soil aggregates
Rhizodeposits in rice paddy soil are important in global C sequestration and cycling. This study explored the effects of elevated CO2 and N fertilization during the rice growing season on the subsequent mineraliz...

Sources and intensity of CH4 production in paddy soils depend on iron oxides and microbial biomass
A paddy soil, with microbial biomass considerably reduced by chloroform fumigation, was treated with low-crystalline ferrihydrite and high-crystalline goethite and with 13C-labeled acetate. In the first 10 days o...

Contrasting response of organic carbon mineralisation to iron oxide addition under conditions of low and high microbial biomass in anoxic paddy soil
In contrast to what is observed in aerobic uplands, microbial biomass and the presence of electron acceptors, such as iron oxides, play a crucial role in regulating soil organic C (SOC) mineralisation in paddy...

Experimental strategies to measure the microbial uptake and mineralization kinetics of dissolved organic carbon in soil
Soil organic matter turnover rates are typically estimated from mass loss of the material over time or from on rates of carbon dioxide production. In the study, we investigated a new way to characterize the co...

Nitrogen fertilization alters the distribution and fates of photosynthesized carbon in rice–soil systems: a 13C-CO2 pulse labeling study
Although nitrogen (N) fertilization is widely used to increase rice yield, its impact on the distribution, transformation, and fates of photosynthetic carbon (C) in rice–soil systems is poorly understood. To a...
