Summary: The study highlights the significance of understanding the dynamics of soil and associated soil organic carbon (SOC) redistribution in fragile karst ecosystems. By utilizing excess lead-210 (Pb-210(ex)), researchers were able to quantify the relationship between SOC and soil redistribution along different toposequences (grassland, forests, agroforestry) in a typical karst region. The results revealed varying levels of soil flux and erosion-induced SOC across the different toposequences, with agroforestry having the highest net soil flux but also posing a higher risk of soil erosion. Additionally, the correlation analysis between Pb-210(ex) and SOC indicated that Pb-210(ex) can be a useful tracer for quantifying the dynamics of the SOC-soil redistribution relationship, particularly in grassland toposequences.

Summary: Nutrient transport from soils to water bodies poses threats to agricultural productivity, food security, water quality, and the environment worldwide. However, the contribution of soil erosion to nutrient loss is often overlooked in nutrient cycle studies. This study assessed the transport of soil nutrients by water and wind erosion across New South Wales (NSW), Australia. The findings revealed significant spatial and temporal variations in nutrient transport rates, with water erosion being the primary contributor. The cost of nutrient transport in NSW was estimated to be billions of dollars annually. This study enhances the understanding of nutrient transport due to erosion in broad nutrient cycle studies.

Summary: In temperate soils in Northern Italy, factors such as land use practices and soil types influence soil quality and SOM dynamics. Agricultural lands with organic material additions showed good soil quality and efficient use of microbial C, while reclaimed peaty soils were prone to degradation due to stress on soil microbial biomass. Conservative management practices in chestnuts reduced soil degradation risk. Evaluating soil parameters recommended by the FAO can help assess sustainable practices and soil quality.

Summary: Understanding the interactions between soil organic matter (SOM) dynamics and soil microbial communities is crucial for predicting the stability and fate of estuarine SOM after human disturbance. This study investigated the microbial communities and chemical composition of different SOM fractions in the Pearl River Estuary under various land uses. The results revealed that land use greatly influenced the quantity and quality of SOM fractions, with microbial communities playing a stronger role in shaping the chemical compositions of different SOM fractions compared to fungal communities. Bacterial diversity showed a stronger relationship with the chemical composition of water-extractable organic matter (WEOM) than abundance. These findings highlight the importance of microorganisms in determining the chemical composition of SOM fractions in estuarine environments.

Summary: Sustainable land management (SLM) is essential for reducing land degradation and desertification, but there is a lack of comprehensive reviews on its spatial distribution, prospects, and challenges. We analyzed data from a global SLM database, academic research papers, and found that dissemination and research on SLM were better in dry subhumid countries with medium scores on the Human Development Index (HDI), while humid countries with low HDI values had lower dissemination and research. Cropland and water erosion were the main focus areas, while other land use types and SLM purposes received less attention. The limited evidence-based SLM dissemination in countries with high soil erosion rates and low HDI scores can be addressed through integrating existing scientific research and SLM databases using the proposed Research Evidence for SLM framework. However, detailed country-specific studies are needed to develop appropriate evidence-based SLM dissemination strategies.

Summary: Soil DNA extraction, a crucial component of soil microbial diversity and abundance research, is influenced by soil sample sizes, but the effects are not fully understood. This study collected soil samples from different ecosystems and analyzed the effects of various sample sizes on microbial abundance, richness, and community composition. The results showed that sample sizes did not significantly affect microbial abundance determination, but they did impact microbial richness, community composition, and co-occurrence patterns. The study suggests that at least 0.25 g of soil should be used for overall microbial diversity analysis, with larger sample sizes required for soils with low microbial cellular density.

Summary: This paper simultaneously analyzes the overconfident and underconfident trading behavior and finds that the level of overconfidence decreases, then increases, and finally decreases again as the number of successful predictions increases when the underconfident behavior is prominent. The expected trading volume in the future first decreases, then increases, and finally decreases as the number of successes increases. Furthermore, the insider's expected profits in the future increase monotonically with the number of successes when it is either small or large, but decrease monotonically when it is in the intermediate range. This completes the analysis of investors' biased behavior.
