Agricultural practices shape microbial communities and change fresh and soil organic matter mineralization in a tropical soil : S11.07-P -1 [PDF]

open access: yes, 2012
Priming effect (PE) is defined as a stimulation of the mineralization of soil organic matter (SOM) due to fresh organic matter (FOM) supply. This process leads simultaneously to a loss of carbon to the atmosphere and to a remobilization of nutrients.

Understanding international students' agency in developing employability: Case study of a post‐1992 university in the United Kingdom

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Employability remains a critical issue for international students in the United Kingdom. This study adopts the Employability Agency Framework proposed by Pham et al. to explore how a group of international students actively exercised their agency to enhance their employability during their Master's studies in the United Kingdom.

Attribution of crop yield responses to application of organic amendments: A critical review

open access: yesSoil & Tillage Research, 2019
Soil organic matter affects soil physical, chemical and biological properties and is thus agronomically important because these factors affect crop yields.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Organic amendments tighten nitrogen cycling in agricultural soils: a meta-analysis on gross nitrogen flux

open access: yesFrontiers in Agronomy
IntroductionUnderstanding how nutrient inputs affect nitrogen (N) transformations and storage is vital for developing sustainable agroecosystems. Organic N inputs, such as crop residues (e.g., cover crop biomass and stover) and animal manures, can ...

Productivity and Emissions in Italian Agriculture: A Farm‐Level Efficiency Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Achieving the European Union climate‐neutrality objectives requires metrics that jointly assess farm productivity and greenhouse gas emissions at a granular level. However, harmonized evidence for benchmarking the productivity–emissions nexus of Italian farms remains limited.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Soil P Status and Nitrogen Fixation on Organic Dairy Farms in Ontario and Nova Scotia [PDF]

open access: yes, 2010
Legumes are a key source of nitrogen (N) in organic production systems. However, there is evidence that reduced inputs may be leading to deficient soil phosphorus (P) on some organic dairy farms (Roberts et. al. 2008).

Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

open access: yesChemFoodChem, EarlyView.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character

open access: yesChemistry – A European Journal, EarlyView.
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.
