Contrasting pathways of carbon sequestration in paddy and upland soils

Global Change Biology, 2021
Paddy soils make up the largest anthropogenic wetlands on earth, and are characterized by a prominent potential for organic carbon (C) sequestration. By quantifying the plant‐ and microbial‐derived C in soils across four climate zones, we identified that

Microplastics shape microbial communities affecting soil organic matter decomposition in paddy soil

Journal of Hazardous Materials, 2022
Microplastics (MPs) can alter microbial communities and carbon (C) cycling in agricultural soils. However, the mechanism by which MPs affect the decomposition of microbe-driven soil organic matter remains unknown.

The key roles of Fe oxyhydroxides and humic substances during the transformation of exogenous arsenic in a redox-alternating acidic paddy soil.

Water Research, 2023
Arsenic (As) from mine wastewater is a significant source for acidic paddy soil pollution, and its mobility can be influenced by alternating redox conditions.

Iron-modified phosphorus- and silicon-based biochars exhibited various influences on arsenic, cadmium, and lead accumulation in rice and enzyme activities in a paddy soil.

Journal of Hazardous Materials, 2022
Contamination of paddy soils with potentially toxic elements (PTEs) has become a severe environmental issue. Application of functionalized biochar for rice cultivation has been proposed as an effective means to reduce environmental risks of these PTEs in

An enhanced pixel-based phenological feature for accurate paddy rice mapping with Sentinel-2 imagery in Google Earth Engine

Isprs Journal of Photogrammetry and Remote Sensing, 2021
Accurate paddy rice mapping with remote sensing at a regional scale plays critical roles in agriculture and ecology. Previous studies mainly employed a single key phenological period (i.e., transplanting) for paddy rice mapping.
