Split N and P addition decreases straw mineralization and the priming effect of a paddy soil: a 100-day incubation experiment
The effect of mineral fertilization and its application pattern on microbial activity and the subsequent CO2 and CH4 emissions arising from soil organic matter (SOM) or added substrate remains unclear. We quantif...

C/P stoichiometry of dying rice root defines the spatial distribution and dynamics of enzyme activities in root-detritusphere
As the primary microbial substrate after shoot cutting, the element stoichiometry of root-detritus (dying or dead roots) influences the enzyme activity in root-detritusphere. However, the effect of the C/P rat...

Performance and mechanisms of thermally treated bentonite for enhanced phosphate removal from wastewater
Optimization of clays as adsorbent for low concentration phosphorus removal from wastewater has received increasing attention in recent years. This study explored the feasibility of using bentonite as an adsor...

Effect of P stoichiometry on the abundance of nitrogen-cycle genes in phosphorus-limited paddy soil
Previous studies have shown that phosphorus addition to P-limited soils increases gaseous N loss. A possible explanation for this phenomenon is element stoichiometry (specifically of C:N:P) modifying linked nu...

Fate of rice shoot and root residues, rhizodeposits, and microbial assimilated carbon in paddy soil - part 2: turnover and microbial utilization
The turnover of plant- and microbial- derived carbon (C) plays a significant role in the soil organic C (SOC) cycle. However, there is limited information about the turnover of the recently photosynthesized pl...

Rice rhizodeposition and carbon stabilisation in paddy soil are regulated via drying-rewetting cycles and nitrogen fertilisation
This study aimed to better understand the stabilisation of rice rhizodeposition in paddy soil under the interactive effects of different N fertilisation and water regimes. We continuously labelled rice (‘Zhong...

Belowground carbon allocation and dynamics under rice cultivation depends on soil organic matter content
The cycling of photosynthate carbon (C) released in the rhizosphere has significant implications for C sequestration, microbial activities, and nutrient availability in the soil. It is known that the soil orga...

Rice rhizodeposition and its utilization by microbial groups depends on N fertilization
Rhizodeposits have received considerable attention, as they play an important role in the regulation of soil carbon (C) sequestration and global C cycling and represent an important C and energy source for soi...

Microbial utilization of rice root exudates: 13C labeling and PLFA composition
The soluble components of rhizodeposition—root exudates—are the most important sources of readily available carbon (C) for rhizosphere microorganisms. The first steps of exudate utilization by microorganisms d...

Phosphorus content as a function of soil aggregate size and paddy cultivation in highly weathered soils
Red soils are the major land resource in subtropical and tropical areas and are characterized by low phosphorus (P) availability. To assess the availability of P for plants and the potential stability of P in ...

Open AccessEffect of simulated tillage on microbial autotrophic CO2 fixation in paddy and upland soils
Tillage is a common agricultural practice affecting soil structure and biogeochemistry. To evaluate how tillage affects soil microbial CO2 fixation, we incubated and continuously labelled samples from two paddy s...

Abundance and Diversity of CO2-Assimilating Bacteria and Algae Within Red Agricultural Soils Are Modulated by Changing Management Practice
Elucidating the biodiversity of CO2-assimilating bacterial and algal communities in soils is important for obtaining a mechanistic view of terrestrial carbon sinks operating at global scales. “Red” acidic soils (...

Tracking the photosynthesized carbon input into soil organic carbon pools in a rice soil fertilized with nitrogen
Replenishment of soils with carbon (C) produced during photosynthesis plays an important role in global C cycling. Nitrogen (N) fertilization is critical for rice production, but its effects on the deposition ...

Effects of Dissolved Organic Matter on Pentachlorophenol Reductive Transformation in Paddy Soils
In this study, 19 paddy soils developed from different parent materials were collected from the A (0–20 cm) horizon in Pearl River Delta basin and divided into four groups (i.e., acid sulfate soils, delta depo...
