Summary: Sulphur deficiency is a common problem in agricultural fields worldwide, and efficient fertilization strategies are still needed. Integrated nitrogen management performs better in supplying and retaining sulphur in soils and plants, while reducing sulphur losses. Farmyard manure is an effective method to improve sulphur availability in soils. Changes in organic carbon, iron, and aluminum oxides and hydroxides in soils are key factors influencing sulphur flow in the soil-plant system.

Summary: It is important to establish an accurate model to predict safe wheat production criteria for cadmium (Cd), especially in areas with high natural background Cd pollution risk. In this study, soil total Cd criteria were derived using a method that integrated cultivars sensitivity distribution, soil aging, and bioavailability affected by soil properties. The soil EDTA-extractable Cd criteria were derived in the same way. Both criteria were validated using field experiment data, indicating their reliability in ensuring the safety of Cd in wheat grains and enabling appropriate agricultural management for croplands.

Summary: This study investigated the soil metabolic response to long-term fertiliser application and its impact on the microbial community using the Woburn Organic Manuring Experiment. Gas chromatography-time of flight mass spectrometer/mass spectrometry (GC-TOFMS/MS) and ultra-high-pressure liquid chromatography-quadrupole time of flight mass-spectrometer/mass spectrometry (UHPLC-QTOFMS/MS) were used to explore the detection of soil microbe-accessible metabolites. High-throughput sequencing was used to detect microbial community abundance. The results showed that farmyard manure application increased soil carbon and nitrogen content. The choice of extraction and detection method influenced the metabolites detected and there were correlations between metabolites and bacterial and fungal taxa in the co-occurrence network.

Summary: The absence of systematic assessment of agricultural soils on the Galapagos Islands highlights the need for targeted management strategies to avoid soil degradation and sustain ecosystem services. Variations in soil fertility parameters and nutrient levels were observed along island age and elevation gradients, emphasizing the importance of site-specific agricultural practices.

Summary: Invasion of giant hogweed can alter soil properties, reduce native plant species and affect nematode communities, particularly decreasing nematode species but not diversity. The invasion also leads to changes in the abundance and composition of soil nematodes, with an increase in plant parasitic nematodes under the influence of giant hogweed.

Summary: This study examined the extractability and critical levels of Pb in soils contaminated with Pb in leafy vegetables. Results showed that certain extractants had significant relationships with Pb concentrations in edible parts and roots of the vegetables. These extractants were suitable for estimating the critical Pb level in soils and the maximum allowable level in leafy vegetables.

Summary: This study investigates the impact of long-term nitrogen (N) inputs on soil dissolved organic matter (DOM) composition. The results demonstrate that N additions significantly alter DOM characteristics and increase recalcitrant DOM components, which benefits soil organic carbon (SOC) storage.

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: Optimized fertilization is an effective strategy for improving nitrogen use efficiency and maintaining high crop yield. This study investigated the long-term impacts of different nitrogen rates on maize yields and soil nitrogen and carbon dynamics. The results showed that the optimum nitrogen rate and combined organic-inorganic nitrogen rate can achieve similar yields as the farmers' nitrogen rate. Furthermore, substituting 20-30% manure for inorganic fertilizer under the optimum nitrogen rate could help reduce soil nitrogen losses and increase soil organic carbon stock for sustainable agriculture.

Summary: This study compares the traditional hot-water method with two common universal extractants for determining boron in sandy soils, and finds that the M3 method consistently extracts higher levels of boron than the other two methods. The study also verifies the unreliability of the hot-water method for soils with high calcium carbonate and organic matter contents.

Summary: It is essential to ensure a consistent supply of nutrients from soil for sustained growth of planted forests, with soil biological communities playing a crucial role. The New Zealand Long-Term Site Productivity trial series has provided valuable insights into the effects of harvest residue and forest floor removal on soil nutrient and organic matter stocks, highlighting the importance of soil health for continuous forest productivity. The research outcomes have led to significant changes in forest soil management practices, emphasizing the role of beneficial soil microbes and the sensitivity of soil microbial communities to harvesting intensity.

Summary: Long-term experiments have been conducted to investigate changes and dynamics of soil organic carbon (SOC) under different cropping systems. Changes in dry combustion methods over time may lead to method bias, affecting the interpretation of data. This study quantifies differences in SOC due to method changes and highlights the challenges in interpreting SOC dynamics. The findings emphasize the importance of providing necessary protocols and data to retrace method changes and recalculate SOC.

Summary: Soil organic carbon content and C-13 natural abundance along soil profile are sensitive to land use changes, with conversion of cropland to forest or grassland beneficial for increasing SOC storage, especially in the 0-60 cm depth. The turnover of SOC in deep soil layers has little impact during the study period.
