Synergistic Effects of Salinization and Artificial Root Exudates on Soil Phosphatase Activity in Coastal Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Coastal soil salinization from rising seawater levels has adverse impacts on soil function, seed germination, and plant growth. Root exudates play a key role in supporting microbial activity, nutrient cycling, and plant health, yet little is known about the combined effects of salinization and the addition of artificial root exudates (AREs) on
