Summary: The types of natural organic matter (NOM) and electrolyte ions significantly affect the aggregation of ferri-hydrite nanoparticles (Fh NPs) in the environment. Dynamic light scattering (DLS) was used to study the aggregation kinetics of Fh NPs. The critical coagulation concentration (CCC) values of Fh NPs aggregation were highest in the presence of 15 mg C/L SRHA in NaCl, and lowest in the presence of ESHA in CaCl2. NOM types, concentrations, and electrolyte ions should be considered for the environmental behavior of NPs.

Summary: The study found that long-term NPK and NPKM fertilizations have contrasting effects on the formation pathway of ferrihydrite-OM complexes in soil. Organic amendments can stimulate the co-precipitation of DOM and ferrihydrite in soil, leading to greater biological C preservation than the adsorption process, and a further enhancement of long-term SOC protection.

Summary: Iron-bound organic carbon (Fe-OC) complexes play an important role in stabilizing soil organic carbon (SOC) against biodegradation. The stabilization of OC and its subsequent release from Fe minerals can affect the priming effect on SOC mineralization. Our study showed that 2LFh-bound glucose resulted in higher CO2 emissions and a negative priming effect on SOC mineralization, compared to 6LFh-bound glucose. The protection of SOC by Fe minerals depends on their crystalline structure and the amount of OC loading.

Summary: Microbial methanogenesis in paddy soils contributes significantly to global anthropogenic methane release, and its regulation by temperature and iron oxides is not well understood. This study investigated the interactive effects of temperature and ferrihydrite on methane production and methanogenic community structure in Chinese paddy soils. The results showed that temperature promoted iron reduction and reduced the number of methanogens, while ferrihydrite inhibited methanogenesis. Overall, these findings provide new insights into the role of iron oxides and temperature in regulating greenhouse gas emissions from paddy soils.

Summary: Systematic studies on natural nanoparticles in soil are limited, but this study on a soil chronosequence in eastern China shows that the NNP content increases with soil cultivation age and the most important factor affecting NNP properties is the soil cultivation age itself, accounting for 60.7% of the total variation. Cluster and principal component analysis revealed a split in NNP samples into age groups, indicating a rapid evolution of NNP properties after an initial period of desalinization.

Summary: Soil specific surface area (SA) is influenced by clay content, organic carbon (OC) content, and clay mineralogy. The contribution of OC to SA varies depending on the clay type and the measurement method used. In this study, the contribution of OC to SA was quantified for different soil types using EGME and water adsorption techniques. The results showed that OC had a positive contribution to SA, except in montmorillonite-rich soils. The contribution of OC to SAH2O was higher than to SAE, and was influenced by the clay mineralogy.

Summary: The attachment of Cu to natural organic matter (NOM) is closely related to its environmental mobility and potential toxicity. Conventional geochemical models often overestimate the activity of metals bound to NOM in assessing the mobility of soil metals. Stable isotope dilution (SID) has been used to estimate the isotopically exchangeable pool of soil metals, but studying the activity of NOM-Cu requires a robust separation and detection method to differentiate free Cu ions from NOM-Cu. This study developed a SID protocol to quantify the labile pool of NOM-Cu and found that a significant proportion of Cu in NOM and soil organic matter is not labile, contrary to common knowledge.

Summary: This study used a boosted regression trees (BRT) model to map the saturated soil organic carbon (SOC) and its density in cultivated lands in Northeast China. The spatial variation of SOC sequestration potential was also calculated based on the difference between saturated SOC and SOC density. The results showed that climate, topography, lengths of cultivation data (LCD), and soil samples significantly influenced the distribution of SOC and its density.

Summary: The study found that water-soluble anionic polychloramide biocides were less affected by soil interference compared to cationic polymeric biocides. Certain soil components, such as polyacrylic acid and cellulose nanocrystals, inhibited the cationic biocides but had little impact on the anionic polychloramide. Glycine and bovine serum albumin reduced the biocidal activity of both anionic and cationic polychloramides by extracting oxidative chlorine, while succinimide increased bacteria deactivation by extracting oxidative chlorine from the polychloramides and transporting it to the bacteria.

Summary: Assessing the surface reactivity of metal (hydr)oxides in weathered tropical soils using a novel probe-ion methodology and surface complexation modelling showed that nanocrystalline ferrihydrite is a better proxy than well-crystallized goethite for describing the reactivity of natural metal (hydr)oxides. Nanoparticles with a mean diameter of 1.5-5.0 nm dominate the reactive fraction of metal (hydr)oxides in these tropical topsoils, with only a small reversibly adsorbed fraction of phosphate being available for sorption reactions determining the solid-solution partitioning of PO4.

Summary: A dedicated soil testing method for estimating available nitrogen in organic production systems is lacking, so this study developed a novel approach to assess potentially mineralisable nitrogen in organically fertilized soils. Using french bean crops, the study found that the PMN index derived from potassium buffer extraction method had a strong correlation with yield and nitrogen uptake, showing its superiority in extracting organic-N compounds from diverse sources. Adopting this method could assist soil testing agencies in providing better nutrient management advice for organic farmers.

Summary: Mitigation measures are needed to reduce chronic dissolved phosphorus (P) losses from agricultural soils to surface waters. A 4.5 year-field experiment tested the performance of a pipe drain enveloped with Fe-coated sand for removing soluble P from drainage water. The results showed that the enveloped pipe drain effectively reduced P inputs, with a removal percentage of 93% for total P. The submerged conditions did not affect the stability of the iron-coated sand or its ability to capture P from drainage water. Enveloping pipe drains with Fe-coated sand is a promising method for reducing dissolved P inputs from agricultural soils to surface waters.

Summary: The availability of phosphorus in agricultural systems is limited, but stimulating earthworm activity can enhance its solubility. This study investigates the mechanisms by which earthworms increase phosphate solubility and finds that mineralization of organic matter, reduction of reactive surface area of metal oxides, and alleviation of competition between organic matter and phosphate contribute to this enhancement. Understanding these mechanisms is important for sustainable agriculture.

Summary: This study investigated the impact of struvite fertilizer on soil nitrogen dynamics and nitrous oxide (N2O) emissions. The results showed that struvite application did not significantly increase N2O emissions in low-phosphorus soil. In high-phosphorus soil, struvite application resulted in lower N2O emissions compared to urea, with no significant difference from the control treatment. Furthermore, struvite powder increased plant nitrogen and phosphorus uptake and yielded similar results to traditional fertilization. In conclusion, struvite application can reduce the risk of nitrogen loss without compromising agronomic performance.

Summary: Current P fertilizer recommendations must be revised to balance crop yield, water quality, and finite P resources. Current soil P tests do not provide the necessary insights. The oxalate extraction method shows promise as an agri-environmental soil test as it measures the total pool of P and the maximum P sorption capacity. These insights are crucial for assessing crop response, P loss risk, and the judicious use of finite P reserves.
