A Single Amendment With Flue Gas Desulfurization Gypsum Improves Saline‐Sodic Soil Quality: Evidence From a Decade‐Long Paddy Experiment

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Saline–sodic soils threaten global agriculture, and flue gas desulfurization (FGD) gypsum is a widely adopted reclamation practice. However, the associated long‐term (> 10 years) legacy effects and temporal dynamics remain poorly understood. We quantified the decadal dynamics of soil quality following a one‐time application of FGD gypsum (40 t
