“…A higher Fe/P molar ratio was found in the CF treatment (Figure S7), which might be due to the higher content of poorly crystalline Fe hydroxides; while a lower Fe/P molar ratio was observed in soils amended with pig manure compost during anaerobic incubations, indicating a relatively higher risk of P loss in the compost‐amended soils than in the chemical fertilizer‐treated soils. Indeed, high P availability induced by organic fertilization regimes may in turn increase the risk of environmental pollution in certain cases (Ando et al., 2022; Hao et al., 2008; Liu et al., 2020; Wang et al., 2012). Furthermore, microbial Fe reduction can, to some extent compensate for P limitation in paddy soils (Wang et al., 2022).…”

“…Seasonal alternation of drying and wetting conditions may cause the redox cycles of iron (Fe) hydroxides, which are expected to promote the formation of poorly crystalline Fe hydroxides (Ginn et al., 2017; Huang et al., 2022). Meanwhile, Fe hydroxides are regarded as the predominant geochemical sinks of phosphate, and the transformation of Fe hydroxides substantially influences the biogeochemical cycle of phosphorus (P) in acidic soils (Ando et al., 2022; Chacón et al., 2006; Wang et al., 2022). Indeed, P is typically associated with Fe oxides in paddy soils (Khan et al., 2019; Kögel–Knabner et al., 2010).…”

“…Indeed, P is typically associated with Fe oxides in paddy soils (Khan et al., 2019; Kögel–Knabner et al., 2010). Generally, the availability of P is higher in paddy soils than in the upland soils because periodic exposure to anoxic conditions can lead to the release of P via the reduction of Fe hydroxides (Ando et al., 2022; Henderson et al., 2012). Therefore, clarifying the influence of management‐induced redox transformation of Fe hydroxides on the availability of P in rice–wheat cropping systems is needed.…”

“…Furthermore, long‐term fertilization affects soil aggregation by influencing the formation of organo‐mineral complexes (Huang et al., 2018), which in turn influences the availability and distribution of P in different aggregate size fractions (Du et al., 2022; Wan et al., 2020). However, continuous overuse of P fertilizer combined with the P release in paddy soils may lead to the leaching of P during the flooding period (Ando et al., 2022; Wang et al., 2012). Thus, a better knowledge of the relationship between the transformation of Fe hydroxides and the availability of P in different aggregate size fractions regulated by different fertilization regimes in the rice–wheat rotation system may provide insights into agroecosystem sustainability.…”

Phosphorus (P) is typically associated with iron (Fe) hydroxides in paddy soils. Our study investigated the impact of different fertilization treatments on the availability of P regulated by Fe redox transformation in a rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping system in the mid‐low reaches of the Yangtze River. Five fertilization treatments were examined: control (CK), chemical fertilizer (CF), 35% CF (P) plus pig manure compost (CFM), 100% CF (P) plus straw (CFS), and 35% CF (P) plus pig manure compost and straw (CFMS). Nine‐year rice–wheat rotations increased the oxalate‐extractable poorly crystalline Fe hydroxides (i.e., Feo) by 33%–87% compared with the initial soil, while fertilization further accelerated this process. Compost application increased the proportion of labile P by 75%–108% and decreased the proportion of non‐labile P by 14%–22% compared with the single chemical fertilization treatment. Furthermore, organic fertilization increased the mass proportions of macroaggregates and macroaggregate‐associated labile P. The Feo was positively correlated with the content of labile P but negatively correlated with the proportion of non‐labile P. Moreover, the reductive dissolution of Fe hydroxides was accompanied by the transformation of P from NaOH‐extractable to NaHCO3‐ and H2O‐extractable phases. These results indicate that seasonal alternation of drying and wetting can progressively drive the redox transformation of Fe hydroxides and promote the formation of Feo, thereby affecting the availability of P. Therefore, we suggested that P fertilizer should be reduced in the rice season due to the reduction of Fe hydroxides, particularly in the compost‐amended soils in the temperate rice–wheat cropping system.

Rice self-sufficiency is central to Indonesia’s agricultural development, but the country is increasingly challenged by population growth, climate change, and arable land scarcity. Agroecological nutrient management offers solutions though optimized fertilization, enhanced organic matter and biofertilizer utilizations, and improved farming systems and water management. Besides providing enough nutrients for crops, the agroecological approach also enhances resilience to climate change, reduces the intensity of greenhouse gas emissions, and improves the biological functions of rice soil. Organic and bio fertilizers can reduce the need for chemical fertilizers. For example, blue-green algae may contribute 30–40 kg N ha−1, while the application of phosphate solubilizing microbes can reduce the use of chemical phosphorous fertilizers by up to 50 percent. The country currently experiences substantial yield gaps of about 37 percent in irrigated and 48 percent in rain-fed rice. Achieving self-sufficiency requires that Indonesia accelerates annual yield growth through agroecological nutrient management from a historical 40 kg ha−1 year−1 to 74 kg ha−1 year−1. The aim is to raise the average yield from the current 5.2 t ha−1 year−1 to 7.3 t ha−1 year−1 by 2050. Simultaneously, controlling paddy field conversion to a maximum of 30,000 hectares per year is crucial. This strategic approach anticipates Indonesia’s milled rice production to reach around 40 million metric tonnes (Mt) by 2050, with an expected surplus of about 4 Mt.
