Summary: This study evaluates the influence of natural and agricultural factors on the dynamics of iron (Fe) in soils. By analyzing five soil profiles in the Puding karst catchment in Guizhou Province, China, the study identified the contributions of natural weathering, soil erosion, and anthropogenic activities on Fe processes. The research revealed that natural chemical weathering and soil erosion primarily occur in the upper layer, causing the loss of Fe during the eluviation-illuviation process. Soil impacted by human activities, such as cultivated land, showed higher Fe content. Fe isotopic fractionation was observed in soils with natural organic matter, resulting in the accumulation of lighter Fe isotopes. This study provides valuable insights into the effects of natural and anthropogenic activities on Fe dynamics, offering information on material cycling in the Puding karst catchment.

Summary: The study suggests that current extraction methods might underestimate the soluble P pool in high or legacy P soils, and recommends using a higher soil-to-water ratio to extract WEP. By increasing the soil-to-water ratio and conducting sequential extractions on eight legacy P soils, it was possible to exhaust the WEP pool, significantly improving the measurement accuracy of WEP.

Summary: Aluminum-bearing reactive mineral phases, represented by Alox, play a significant role in soil organic carbon (SOC) stabilization in arable topsoil in humid continental climates, explaining approximately 48% of the spatial variation in SOC. The study also showed that approximately 80% of SOC is stored in silt- and clay-sized fractions, indicating the importance of Al-bearing reactive mineral phases in SOC stabilization. Including spatially-variable crop yields as a proxy for carbon inputs improved the prediction of SOC variation in the study area.

Summary: This study investigated the effect of Fe and Al on the distribution characteristics of phosphorus during solidification of Si-Fe-Al alloy melt. The results showed that Fe and Al can reduce the segregation coefficient of phosphorus in silicon, but the similarity in crystal structure hinders the enhanced separation of phosphorus from silicon. Accurate understanding of the distribution characteristics of phosphorus in metallurgical grade silicon is of great significance for the optimal design of purification schemes.

Summary: Soil carbon (C), nitrogen (N), and phosphorus (P) contents and their stoichiometric ratios in response to agricultural use were generally similar across the four climate zones, with P increasing and C:N:P ratios decreasing. More intensive agricultural practices and stronger biological and geochemical processes in warmer and wetter zones led to more pronounced differences in soil C, N, and P contents and their stoichiometric ratios among land-use types, compared to cooler and drier climates.

Summary: Land use is a critical factor in soil carbon cycling and content changes. The priming effect, which refers to CO2 emissions resulting from the decomposition of fresh carbon inputs, is unpredictable but important in nutrient mobilization. This study, conducted across 22 European countries, revealed that priming effects were generally negative in both seminatural and cropland soils. The magnitude of priming effects was influenced by land use, with seminatural ecosystems showing higher levels compared to croplands. Additionally, the type of crop did not significantly impact the priming effects.

Summary: Over the past centuries, peatlands have been drained and degraded, resulting in the release of a significant amount of CO2. Raising the water table in organic grassland soils is proposed as a solution to meet national greenhouse gas emission targets. However, there is a lack of information regarding the drainage status of these soils, leading to overestimation of emissions in national inventories. Evidence suggests that only a small proportion of the grassland peat area has been effectively drained, and the lack of long-term maintenance further reduces the efficiency of drainage systems. Scenario testing showed that the estimated emissions from the most probable scenario are significantly lower than current national inventory estimates.

Summary: The study calculated minimum temperature requirements for ancient types of barley in sites across the Scottish Isles, Faroes, and Iceland. It compared these thresholds with reconstructions of annual cropping season degree days (CSDD) using temperature and tree-ring data to investigate site suitability for barley cultivation. The results showed differences in CSDD between regions and time periods, with occasional challenges and periods of abandonment, but also the resilience of barley cultivation due to well-adapted strains and socio-economic factors.

Summary: This study conducted a meta-analysis of 173 studies on the uptake and accumulation of metallic nanoparticles (MNPs) in crops. The results show that root application is the main method used, and plants preferentially take up essential elements as MNPs. Additionally, smaller particle size and more negative zeta potential increase metal accumulation, while non-essential elements are more commonly acquired as dissolved metals.

Summary: The limited usability of rose waste hampers the development of a sustainable circular rose cultivation industry. The unfavorable properties of rose horticultural waste, such as high lignin content in stems and high polyphenol levels in flowers and leaves, pose challenges for reusing it. This study aimed to explore the potential of composting rose waste with other available green wastes or mature rose compost to obtain improved compost with high fertilizing capacity. The results showed that all mixtures resulted in stable and mature compost after six months, with suitable macro- and micro-nutrient concentrations. The ligneous nature of rose waste does not prevent an effective composting process, but an extended maturation phase could be preferred for optimal results. Additionally, mature rose compost demonstrated a high disease suppressive capacity against common rose pathogens.

Summary: Understanding the impact of land use/land cover change on hydrology is crucial for sustainable water resource management. This study used the SWAT model to assess the effect of land use/land cover change on runoff in the Rur basin, Germany. The model was calibrated and validated using observed data from 2000 to 2015, and statistical parameters were used to evaluate its performance. The results showed that the SWAT model captured the spatio-temporal patterns and effects of land use/land cover change on stream runoff, despite the heterogeneity of runoff responses. The study found that the conversion from deciduous forest to urban settlements, agricultural land, or grasslands increased the overall basin runoff by 43%, 14%, and 4% respectively.

Summary: Straw incorporation (SI) combined with N fertilizer has been shown to affect soil N2O emission and N-related functional microbes in agriculture. In a two-season experiment in China, SI was found to decrease seasonal N2O emissions when combined with N fertilizer, increase crop yield, alter microbial community composition, and decrease the abundance of certain functional genes. However, in the absence of N fertilizer, SI promoted the growth of certain genera that were positively correlated with N2O emissions. Soil moisture and NO3- concentration were identified as the major factors affecting N-related microbial community structure. The study concludes that SI can enhance yield and alleviate fertilizer-induced environmental costs in intensively farmed fields in northern China.
