Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal 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.

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Small‐Scale Topographic Variability Shapes Molecular Diversity of Organic Matter in Coastal Dune Soils

open access: yesJournal 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.
