Assessing plant water status: Part 2 – Non‐destructive and remote sensing approaches
Journal of the Science of Food and Agriculture, EarlyView.Abstract Precise, real time and non‐destructive assessment of plant water status is important for advancing plant physiological understanding, optimizing water usage, improving crop resilience and supporting precision agriculture in the face of increasingly variable climatic conditions.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Grapevine phenolic compounds play key roles in plant defense and wine quality. Composition depends on factors such as maturity and infections such as grey mold caused by Botrytis cinerea. Grapevines respond to infections by actively modifying their phenolic profile.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis
Land Degradation &Development, EarlyView.ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Land Degradation &Development, EarlyView.ABSTRACT Maintaining soil health and crop productivity in the semi‐arid Vertisols of central India poses a significant challenge under intensive agricultural practices. This 6‐year field study assessed the combined impact of different tillage methods, maize‐based crop rotations, and nitrogen management on soil's physical, chemical, and biological ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Frequency scaling of rain attenuation [PDF]
, 2007 The most fundamental obstacle encountered in designing communication system at millimeter waves is attenuation due to rain especially at frequencies above 10GHz. Rain attenuation, however, increases approximately as the square of frequency.

Materials and Corrosion, EarlyView.The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability
