Mercury cycling in a flooded rice paddy [PDF]

open access: yesJournal of Geophysical Research: Biogeosciences, 2012
In 2008 and 2009, mercury (Hg) cycling was investigated in a flooded rice paddy in the Wanshan Hg mining region of eastern Guizhou, China, in the rice‐planted (2008 and 2009) and fallow (2009) sections of the same paddy. In the rice‐planted section, pore water was more acidic and pore water methylmercury (MeHg) concentrations were higher compared to ...

Synthetic microbial communities for engineering climate‐smart biofertilizers

open access: yesiMeta, EarlyView.
Global agricultural productivity is increasingly destabilized by climate change—driven droughts, floods, extreme heat, and severe storms. Although the climate‐smart agriculture (CSA) framework addresses these challenges, implementation has focused mainly on plant genetics and agronomic inputs, leaving the adaptive potential of the crop microbiome ...

Increased Income from Seasonally Flooded Rice Fields through Community Based Fish Culture in Bangladesh and Vietnam

open access: yesPlant Production Science, 2005
In extensive river floodplains and deltaic lowlands, floods lasting several months render the land unavailable for crop (often rice) production during the rainy season.

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

open access: yesiMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

Understanding nutrient competition between Echinochloa spp. and Oryza sativa L.

open access: yesJournal of Plant Protection Research, 2020
Weed competition in southern Brazil is one of the main limiting factors for Oryza sativa L. (flooded rice) yield. Echinochloa spp. (barnyardgrass) occurs at a high frequency.

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.
