Summary: The problem of nutrient-poor land in Indonesian rice farming is exacerbated by the lack of organic matter and flooding, leading to increased methane emissions. This study examines the impact of organic fertilizers and rice varieties on yield, methane emissions, and the feasibility of farming in nutrient-poor fields. Results show that the combination of Inpari 20 variety and rice straw compost has the highest potential for development.

Summary: Cadmium pollution poses a growing threat to rice production in acidic paddies in south China. The addition of Chinese milk vetch, rice straw, chemical fertilizer, and lime effectively reduces the accumulation of Cd in rice grains and increases soil pH value and organic matter content, converting Cd into a stable form in soil.

Summary: This study investigated the effects of peach branch derived fertilizer (PB), cow manure derived fertilizer (CM), and silicon liquid fertilizer (Si) on the growth and Cd uptake of Spinacia oleracea L. in Cd contaminated soil. Results showed that PB and CM significantly increased shoot dry mass and reduced shoot Cd accumulation, while Si had no effect on plant biomass but reduced root Cd uptake. CM also significantly decreased soil-available Cd.

Summary: Silicon spraying can reduce the accumulation of cadmium in rice grain, but the effectiveness varies among different rice varieties. A field study was conducted to evaluate the impact of silicon on cadmium accumulation and transport in four rice varieties. It was found that some varieties were responsive to silicon treatment, while others were not. The first node in the stem was identified as the key site for cadmium transport influenced by silicon application, and OsZIP7 was identified as a key protein involved in this process.

This variety, along with six others identified as low-grain-Cd rice, provides a promising solution to mitigating the risk of excess Cd accumulation in rice by efficiently quantifying the genetic nature of grain-Cd accumulation.

Summary: Both inorganic and organic fertilizers increase the concentration of methylmercury (MeHg) in rice grains, but through different mechanisms. Inorganic fertilizers enhance mercury methylation by increasing the bioavailability of mercury and the relative amount of Hg-methylating microbes. In contrast, organic matter in organic fertilizers is the main driver for the increase in MeHg concentrations in rice grains and can also immobilize mercury in soil.

Summary: In this study, a nanoplatform decorated with Pt and Au nanoparticles loaded with indocyanine green was developed for precise photodynamic therapy (PDT) and microenvironment improvement in choroidal neovascularization (CNV) treatment. The nanoplatform could penetrate the internal limiting membrane and target CNV, while Pt nanoparticles acted as catalase-like agents to relieve hypoxia and enhance PDT, and Au nanoparticles showed anti-inflammatory and anti-angiogenesis properties. Compared to verteporfin treatment, the nanoplatform significantly downregulated the mRNA expressions of hypoxia-inducible factor-1 alpha and VEGF, achieving a comprehensive CNV treatment effect.

Summary: This study investigated the effects of fertilization with iron on cadmium (Cd) uptake and distribution in rice. It was found that increasing the supply of iron significantly reduced Cd accumulation in the shoots by inhibiting Cd translocation from roots to shoots. Increasing the ionic soluble pectin (ISP) content and decreasing citric acid (CA) in the roots provided more Cd-binding sites in the cell wall, reducing the mobility of Cd in xylem. However, low iron or excess iron facilitated Cd uptake in rice roots. Soil fertilization with iron strongly reduced Cd accumulation in rice grain by immobilizing Cd in the roots.

Summary: By applying substances rich in Ca and Si, the accumulation of arsenic and cadmium in rice grains can be reduced while increasing yield. The plant-available Si in soil plays a crucial role in the root-to-grain transport of arsenic and cadmium. The combination of Ca- and Si-rich substances can effectively decrease the pollutant mobility in soil and reduce the accumulation in rice grains.

Summary: The application of rice straw, milk vetch, lime, and their combined use can significantly reduce the concentration of Cd in rice grains produced with acidic paddy soil. This reduction is mainly achieved through the combined effects of reducing Cd availability in the rhizospheric soil, Cd sequestration in iron plaque, and Cd uptake by the roots.

Summary: The objective of this research was to study the differences in the enrichment and transport capacity of heavy metal chromium in farmland soil by different maize cultivars, and it is of great significance to screen out the maize varieties that meet the food safety standards and repair the heavy metal chromium in farmland soil. The experiment found that among the tested maize cultivars, 68.06% had kernel chromium content lower than the national standard. Significant differences were observed in the chromium content of the kernels, stems, leaves, and roots of all cultivars. By cluster analysis, maize varieties were divided into different groups based on kernel chromium content and the content of chromium in stem and leaf. It was concluded that seven maize varieties could be promoted as chromium maize cultivars with low kernel and high stem-leaf accumulation.

Summary: This study in the subtropical region of East China investigated greenhouse gas (GHG) reduction in rice-wheat rotation systems through drainage methods. The results showed that drainage significantly decreased CH4 emissions but increased N2O emissions. The mechanisms behind this included the decrease in soil water content and organic matter, and the increase in soil nitrogen content. SD and DD treatments not only ensured stable production but also effectively reduced GHG emissions.

Summary: Using different fertilizer types, the combination of ammonium sulfite and calcium magnesium phosphate was found to be the most effective in reducing the content of heavy metal chromium (Cr) in both soil and maize grains. This combination not only improved the pH and organic matter of the soil but also resulted in a significant reduction in the Cr content of maize roots, straws, and grains. It also met the national food safety standard of China.
