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

open access: yesJournal 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 ...

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Breeding for multi‐stress resilience in crops: Myth or possibility?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

Advancing Green Human Resource Management Aspects and Practices in Organizations: The Power of Fuzzy Importance Performance Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Drawing on intersections between the Ability–Motivation–Opportunity (AMO) framework and the Resource‐Based View of the Firm (RBV‐F), this research critiques key convergent and divergent theoretical aspects of Green HRM. This approach led to the formulation and implementation of a Fuzzy Importance–Performance Analysis (FIPA) method to evaluate ...
