Quantitative understanding of the impact of flooding durations on Cd variations in an acidic paddy soil during the flooding and drainage processes

open access: yesSoil Security, 2023
The solubility and transformation of cadmium (Cd) are controlled by paddy soil pH, whereas paddy soil pH varies during flooding and drainage and is significantly controlled by flooding durations.

Community Profile and Drivers of Predatory Myxobacteria under Different Compost Manures

open access: yesMicroorganisms, 2021
Myxobacteria are unique predatory microorganisms with a distinctive social lifestyle. These taxa play key roles in the microbial food webs in different ecosystems and regulate the community structures of soil microbial communities.

The influence of Shewanella oneidensis MR-1 on the transformation of iron oxides and phosphorus in a red soil

open access: yesSoil and Water Research, 2022
In this study, Shewanella oneidensis MR-1, an iron (Fe)-reducing bacterium, was inoculated to a red soil, which was then incubated. Soil samples were taken regularly to analyse the variation of iron oxides and phosphorus (P) fractions. The results showed

Function of Biohydrogen Metabolism and Related Microbial Communities in Environmental Bioremediation

open access: yesFrontiers in Microbiology, 2019
Hydrogen (H2) metabolism has attracted considerable interest because the activities of H2-producing and consuming microbes shape the global H2 cycle and may have vital relationships with the global cycling of other elements.

Identification of Critical Source Areas (CSAs) and Evaluation of Best Management Practices (BMPs) in Controlling Eutrophication in the Dez River Basin [PDF]

open access: yes, 2019
Best Management Practices (BMPs) are commonly used to control pollution in the river basins. Prioritization of BMPs helps improve the efficiency and effectiveness of pollution reduction, especially in Critical Source Areas (CSAs) that produce the highest

Quantification of red soil macropores affected by slope erosion and sediment using computed tomography

open access: yesVadose Zone Journal, 2023
Soil structure is an important factor interacting with soil erosion and sediment processes. However, few studies have focused on the relationship between soil macroporosity and soil erosion across different terrains. The aim of this study was to quantify

Modeling soil-water dynamics for diverse environmental needs [PDF]

open access: yes, 2006
Accurate representation of the top soil matrix with special attention to the scales present is important to the dynamics of water flow and fate of pollution at field, farm and watershed scales.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Rural sustainable drainage systems:a practical design and build guide for Scotland's farmers and landowners [PDF]

open access: yes, 2016
Soil cultivation, manure / fertiliser applications and chemical spraying can all contribute to diffuse pollution from agricultural land. Rainfall runoff from farm roads, tracks, yards and dusty roofs are also potential sources of diffuse pollution ...
