Assessing Starch-Based Phosphorus Fertilizers in Calcareous Soil-Wheat System: Rhizosphere Inorganic P Fractionation and Transformation Kinetics
ABSTRACT Efficient phosphorus (P) management in calcareous soils remains challenging due to rapid fixation into Ca-dominated, poorly available forms. Building on a previous bulk-soil study, this greenhouse experiment evaluated inorganic P (Pi) fractionation and transformation kinetics in the rhizosphere following appli...
