Summary: The effects of three types of urea fertilizers on soil N transformation processes were examined in a laboratory experiment. It was found that humate-coated urea (U_HA) showed advantages in reducing N losses, increasing N-NH4 content, and decreasing N2O emissions compared to conventional urea. U_HA also promoted soil respiration and microbial activity, making it a promising tool for reducing N losses in soils.

Summary: Iron (Fe) deficiency and manganese (Mn) deficiency have negative effects on the growth and physiological parameters of soybean cultivars. The deficiencies affect photosynthetic efficiency, nutrient uptake, and antioxidant activity. Simultaneous Fe and Mn deficiency had a more pronounced impact compared to individual deficiencies. However, rational fertilization of Fe and Mn can improve these parameters in hydroponic conditions.

Summary: Organic and inorganic soil amendments are used to enhance crop productivity, improve soil properties, sequester carbon, and restore contaminated and saline soils. This study investigated the effects of various zeolite composites mixed with lignite or leonardite on the biomass production and root morphology of spring wheat and rapeseed. The results showed that the application of mineral fertilizers with zeolite-carbon composite significantly increased the aboveground biomass of spring wheat. However, only the treatment with zeolite-carbon composite and leonardite improved the root length and biomass of spring wheat, while no other amendments had a significant effect on the properties of rapeseed roots.

Summary: The study found that using Thiobacillus bacteria and iron waste to supply soybean iron requirement in calcareous soil is feasible, with T. ferrooxidans showing higher bioleaching potential. Simultaneous application of T. thiooxidans and T. ferrooxidans significantly increased iron uptake by soybeans.

Summary: In this study, iron-reducing bacteria were attached to rice husk biochar by synthesizing nano-loadings of iron tetroxide, which improved the ammonia oxidation efficiency to 81.82%. The electron shuttle provided by the biochar increased the carbon consumption rate and further improved the COD removal efficiency to 98.00%. Additionally, the Feammox process coupled with iron denitrification can reduce nitrate accumulation and achieve nitrogen/iron recycling.

Summary: In this study, a new inhibitor NaHA was used to effectively separate hematite and quartz. The results showed that an appropriate concentration of NaHA could selectively inhibit hematite and prevent the further adsorption of other substances by changing the zeta potential of hematite and quartz surfaces.

Summary: This study investigated the impact of elevated atmospheric CO2 and iron availability on the proteomic profile of soybean plants. The results showed that under elevated CO2, sugar concentration and biomass increased, but Fe-limitation led to decreased photosynthesis and biomass. Pathway enrichment analysis revealed changes in various metabolic pathways in response to Fe-stress. Additionally, protein abundance related to glycolysis, starch and sucrose metabolism, and biosynthesis of plant hormones increased under eCO2.

Summary: Stable Fe isotopes in freshwater systems, especially in meromictic lakes, have recently been measured. This study focuses on two small dimictic boreal shield headwater lakes and reveals the large fractionations of 556Fe in dissolved, particulate, and sediment Fe, which have implications for biogeochemical cycling and acquisition of Fe by cyanobacteria in Earth's early ferruginous oceans.

Summary: This study uses a global ocean biogeochemical model with active Fe isotope cycling to investigate the impact of anthropogenic Fe sources on surface ocean dFe and δFe-56(diss). The results show that the response of dFe, δFe-56(diss), and primary productivity is variable and regulated by the biogeochemical regime, rather than following the footprint of atmospheric deposition. The study also finds that while δFe-56(diss) can trace anthropogenic input, its response is attenuated by fractionation during phytoplankton uptake, but amplified by other isotopically-light Fe sources.

Summary: The study showed that G7 is a biodegradable alternative to EDTA for supplying Mn, maintaining nutritional balance compared with G6, and reducing Fe uptake by plants. The efficacy of the Mn complexes depended on both the ligand and the Mn:ligand ratio, with the 1:1 and 1:2 molar ratios of Mn2+:G7 being the most effective complexes in the short term.

Summary: This study investigates the capacity of [S,S]-EDDS to solubilize micronutrients from agronomic soils and enhance plant nutrition. The results show that [S,S]-EDDS has a high capacity to solubilize iron and other micronutrients, with the best results observed in sandy-clay soils with low iron content, typical of Mediterranean areas. The study supports the direct application of the ligand to soils and the possible use of ligand-producing bacteria in biotechnology applications.
