Cover Story: Phosphorus (P) scarcity—driven by P fixation with aluminum and iron (hydr)oxides—and calcium (Ca) deficiency remain critical challenges in acidic paddy soils. This study investigated P management using humic acid (HA), gypsum (FG), and their combinations (HA + FG). The findings revealed that HA alone is an effective amendment, as it not only promotes P availability but also sustains rice production. In contrast, FG, either alone or combined with HA, induced Ca-P brushite mineral formation, which limits P uptake and rice yield. Although HA + FG improved soil properties, including TOC, N, S, and exchangeable Ca and S, it failed to boost rice yield, as higher TOC causes the stabilization of non-labile organic P (e.g., humic Po and IHP), further reducing P availability and P uptake. Thus, HA alone is a suitable soil amendment for acidic paddy soils. View this paper
