Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
