Efficiency Of Triple Superphosphate Fertilizer To Stabilize Cadmium In Different Soil Texture Characteristics, Chatchavaporn Yingsombat, Usarat Thawornchaisit

Applied Environmental Research

This research investigated the effectiveness of Triple Superphosphate (TSP) as a stabilizing agent for cadmium (Cd) in three representative soils having different texture characteristics (loamy-sand, clay loam, and clay soils). Results showed that addition of TSP proved to be an effective method for reduction of Cd leachability in all Cd contaminated soils. The partitioning of Cd from the potentially available phase to the more stable phase was observed in all TSP treatments based on the sequential extraction data. Moreover, performance of TSP to immobilize Cd depended on soil types and compositions. The effectiveness of TSP to reduce Cd leachability was …
