Impact of Land use on soil quality: Insights from the forest-savannah transition zone of Ghana

open access: yesHeliyon
Land use changes have a profound impact on soil fertility and agricultural production systems in the Forest-Savannah Transition Zone (FSTZ) of Ghana. Soil erosion and shortened fallow periods exacerbate soil fertility loss, further degrading soil quality.

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).

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

open access: yesAdvanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Nanozymes at the Bio‐Nano Interface: From Synthesis, Defect Engineering, Catalytic Behavior in Biological Microenvironments, and Biosafety Implications

open access: yesAdvanced Materials Interfaces, EarlyView.
Nanozymes (NZs) have emerged as versatile artificial enzymes with tunable catalytic properties driven by atomic coordination, defect engineering, and surface chemistry. This review presents a bio–nano interface framework linking synthesis strategies, structural design, and catalytic behavior within complex biological microenvironments.

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Defining dynamic soil property and soil health reference conditions for soil survey

open access: yesSoil Advances
Correlating soil health indicator values with the soil map units defined by United States Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS) Soil Survey can help identify soil health indicator benchmark values for a particular

Distribution and effects of ionic titanium application on energy partitioning and quantum yield of soybean under different light conditions

open access: yesPhotosynthetica, 2019
Soybean growth and development response to ionic titanium application have never been investigated. Therefore, such study is needed to better explain the titanium (Ti) application for soybean crop.

Landscape system mapping of the humid Baturié massif and its semi-arid piedmont (Northeastern Brazil): A multilayer integration of environmental parameters [PDF]

open access: yes, 2006
The Baturité massif is the erosional remnant of an Early Cretaceous rift shoulder. Humid bioclimatic conditions on this upstanding residual landform contrast with the semi-arid conditions of the surrounding plain ('Sertão').
