Hysteretic seepage analysis in unsaturated soil covers
, 2012 This paper aims to study numerically the effect of hysteresis on the hydraulic behaviour of unsaturated soil covers. The Richards equation is coupled with the hysteretic soil water retention curve (SWRC), to describe the flow in unsaturated soils.

Design charts for the stability analysis of unsaturated soil slopes [PDF]
, 2009 Simple limit equilibrium analyses can be performed to determine the Factor of Safety (FOS) against slope failure of unsaturated soil slopes. However, many of the input parameters needed for these analyses are highly variable, and the FOS value obtained ...

Irrigation and Drainage, EarlyView.ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Food Security Versus Environmental Health: The Nitrogen Dilemma
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Journal of Plant Nutrition and Soil Science, EarlyView.Topography shapes ecosystem controls, driving microclimate, hydrology, and vegetation, which, in turn, influence topsoil traits and DOM composition in coastal dune soils. Distinct molecular patterns emerge across north‐facing and south‐facing slopes and dune valleys.

Journal of Raman Spectroscopy, EarlyView.Common‐mode rejection (CMR) is introduced as a physics‐motivated preprocessing method for shifted excitation Raman difference spectroscopy (SERDS) that removes the shared background of paired measurements while preserving the noncommon excitation‐dependent component. Applied to more than 900 North American soil samples, CMR improves soil organic carbon

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Stored food products are highly vulnerable to infestation by insects and mites, resulting in significant postharvest losses worldwide. Plant‐derived bioactive compounds represent promising eco‐friendly alternatives to synthetic pesticides.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
