Isolation and Characterization of Hydrocarbon-Degrading Bacteria in Top and Subsoil of selected Mechanic Workshops in Benin City Metropolis, Nigeria

Journal of Applied Sciences and Environmental Management, 2017
The isolation of hydrocarbon-degrading bacteria in topsoil and subsoil samples of selected mechanic workshops located in the Benin metropolis was carried out. The highest and lowest bacterial counts in topsoil samples were found out to be 2.94 x 106 CFU/

Genome‐Wide Association Study Elucidates the Genetic Architecture of Manganese Tolerance in Brassica napus

Plant, Cell &Environment, EarlyView.
ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

OsPIP2;1 impacts root hydraulic conductance and is a candidate gene for a drought avoidance QTL on rice chromosome 7

Plant Biology, EarlyView.
In this study, we identified a rice plasma membrane intrinsic aquaporin (OsPIP2;1) as the candidate gene for a chromosome 7 locus driving drought avoidance, supported by established and novel physiological experiments measuring root hydraulic conductance in near isogenic and RNAi knockdown lines.

Distribution of Mineral Nitrogen in Soil in Relation to Risk of Nitrate Leaching in Farms with Irrigated Vegetables and Early Potatoes

Journal of Horticultural Research, 2018
Vegetable production may be the source of excessive residual nitrate that is prone to leaching to waters. To ascertain the risk of nitrate leaching in water collection area, the content of soil mineral nitrogen (Nmin = N-NO3− + N-NH4+) down to 120 cm ...

Specialized Committees of International Organizations an Important Source of Organizational Autonomy

Regulation &Governance, EarlyView.
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show

End‐of‐season corn stalk analysis as a tool to fine‐tune potassium and nitrogen management

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Corn (Zea mays L.) requires proper nutrient management for optimal growth, and tissue testing plays an important role in refining recommendations. Corn stalk nitrate test (CSNT) is used to evaluate nitrogen (N) management; however, a comparable plant‐based diagnostic tool for potassium (K) is lacking. This study evaluated extractants for stalk‐

Tall fescue performance in response to natural organic and synthetic granular fertilizers and Rhizoctonia solani inoculation

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Repeated applications of natural organic based fertilizers can benefit soil health and potentially suppress some turfgrass diseases. One of the major summer diseases affecting many lawns is brown patch (caused by various Rhizoctonia and Rhizoctonia‐like species).
