摘要： Unlike synthetic fertilizers, organo-mineral fertilizers (OMFs) improve phosphorus use efficiency (PUE) by reducing inorganic phosphorus (P-i) adsorption and precipitation. Starch-bound P fertilizer, renowned for its mobility and efficiency, exhibits unclear P-i transformation mechanisms when incorporated into an OMF formulation that has been investigated in this study to address the gap. We conducted a 16-week greenhouse pot incubation with four treatments: a non-fertilized control (CK), NaH2PO4 (IP), starch-no additionally bound P + IP (SIP), starch-bound P + IP (SP) at a 50 mg P kg(-1) (97.5 kg P ha(-1)) soil application rate per pot; and analyzed incubated soil samples after 1, 4, 8, 12, and 16 weeks using a modified sequential extraction to determine Pi fractions. We found that P fertilizer type significantly influenced Pi distribution and transformation. After one week, IP and SIP predominantly transformed into labile P (Ca-2-P) fraction (similar to 60% and similar to 45% of applied P, respectively), while SP treatment increased Fe-P (48.9 +/- 1.94 mg P kg-(1) after 16th week, similar to 33% of applied P) but reducing Ca-P's fixations throughout the study. The transformation rate of applied P to labile P and moderately labile P (Ca-8-P) and the decay rate constant of labile P to moderately labile P followed the order of SP < SIP < IP, with an inverse half-life trend. Thus, starch-based OMF (SP > SIP) improved P mobility and extended phyto-availability, minimizing rapid fixation compared to conventional P fertilization. Our findings also suggest a lower short-term environmental risk for starch-bound P-based OMFs.
