To gain a deeper understanding of the interaction between soil erosion and the carbon cycle, this study assessed the effects of two tillage practices, as slope-ridge tillage (SRT) and cross-ridge tillage (CRT), in controlling soil erosion on long gentle sloping farmland in the Northeast black soil region in China, while evaluating spatial variations in erosion rates, SOC content, and SOC fractions using the Caesium-137 (¹³⁷Cs) technique combined with wavelet analysis. The findings revealed lower ¹³⁷Cs inventories for both SRT (732.96 Bq·m⁻²) and CRT (1000.98 Bq·m⁻²) compared to the reference value (2468.77 Bq·m⁻²), confirming the occurrence of soil erosion. CRT showed a significantly lower erosion rate (3056.65 t km²·a⁻¹) than SRT (4409.04 t km²·a⁻¹), indicating greater effectiveness in erosion control. Wavelet analysis further uncovered periodic erosion-deposition patterns under both tillage practices, which corresponded to variations in SOC content and its fractions. A significant negative correlation was observed between SOC content and cumulative mineralization, with soil erosion rate emerging as a critical driver of these relationships. Correlation analysis confirmed that SOC fractions play a crucial role in driving SOC mineralization and are intricately linked with SOC dynamics. Random forest analysis identified soil erosion rate, SOC, and dissolved organic carbon (DOC) content as key factors influencing SOC mineralization under SRT. The findings suggest that CRT is more effective in reducing soil erosion by modifying microtopography, thereby minimizing the migration of mineral-associated organic carbon (MAOC) and enhancing SOC retention. This research provides critical insights for developing sustainable land management practices in the region, mitigating the adverse impacts of erosion on the carbon cycle.</div></div>","PeriodicalId":48622,"journal":{"name":"International Soil and Water Conservation Research","volume":"14 1","pages":"Article 100558"},"PeriodicalIF":7.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147410844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These problems are especially exacerbated in regions subjected to intense rainfall, where their impacts can be particularly severe. In China, the suburban areas of Beijing have experienced considerable challenges associated with both soil erosion and non-point source pollution. Under different rainfall types, the impact mechanisms of rainfall, vegetation, and land preparation on soil erosion and non-point source pollution are highly complex and have not yet been fully understood. This study is based on soil erosion (runoff, sediment yield) and non-point source pollution (TN, Total nitrogen; TP, Total phosphorus; COD, Chemical Oxygen Demand) data from 130 erosive rainfall events (Classified as light, moderate, heavy and extreme rainfall based on 24-h precipitation) across 16 runoff plots from 2010 to 2023. The runoff plots consist of different vegetation and land preparation measures. The characteristics of soil erosion and non-point source pollution under four different rainfall types and different soil conservation measures were compared. Additionally, the impacts of rainfall, vegetation, and land preparation on soil erosion and non-point source pollution under different rainfall types were explored. The results indicate that the frequency of extreme rainfall events accounts for only 16.9 % of erosive rainfall, yet the runoff, sediment yield, TN, TP, and COD they generate account for 40.7 %, 35.0 %, 37.9 %, 33.4 %, and 41.9 % of the total, respectively. Vegetation and land preparation measures have a significant effect on reducing runoff, sediment yield, TN, TP, and COD. The primary factor influencing runoff, TN, TP, and COD was maximum 30-min rainfall intensity (I₃₀), with correlation coefficients of 0.33, 0.20, 0.30, and 0.28, respectively (<em>p</em> &lt; 0.01). As rainfall intensity increases, the contribution of vegetation to soil erosion and non-point source pollution increases from 0.7 % under light rainfall to 41.1 % under extreme rainfall. The combined effect of vegetation and land preparation increases from 1.7 % to 14.4 % under extreme rainfall. Under the same rainfall conditions, the contribution of vegetation and land preparation to soil erosion is significantly higher than that to non-point source pollution. The study identifies the mechanisms by which rainfall, vegetation, and land preparation influence soil erosion and non-point source pollution under varying rainfall conditions. These findings offer valuable insights for soil conservation and non-point source pollution management, particularly in areas experiencing extreme rainfall events.</div></div>","PeriodicalId":48622,"journal":{"name":"International Soil and Water Conservation Research","volume":"13 4","pages":"Pages 892-908"},"PeriodicalIF":7.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, uncertainty still exists about the expected impact of such a reduction on wheat yield across the EU. In this work, we construct a regression model to evaluate the possible impacts of fertilizer reduction and climate change on wheat yields by 2050. The regression model quantifies the effects of soil properties, soil management, and climate on wheat yields at the EU scale. In addition, we simulate two scenarios, one based on the EU fertilizer targets only and the other focusing on climate change impact (+4 °C). The results show an important effect of soil phosphorus, nitrogen, and potassium content, soil carbon-to-nitrogen ratio, and nitrogen inputs on the variation in wheat yields across the EU, next to climate. The scenario analysis suggests that reducing N and P inputs by 20 % leads to wheat yield losses of up to 5 %, an effect that can rise to 50 % yield reduction by 2050 under climate change. Fertilizer reduction leads to most significant yield decreases in France, Germany and Northern Italy, while climate change reduces yields mostly in Southern Europe. Beyond highlighting relevant regional patterns, our results show how EU fertilizer reduction targets are expected to have a small impact on wheat production compared to climate change.</div></div>","PeriodicalId":48622,"journal":{"name":"International Soil and Water Conservation Research","volume":"13 4","pages":"Pages 733-743"},"PeriodicalIF":7.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges remain in capturing how both natural and human-induced erosion processes interact over space and time to influence soil degradation. Current assessment methods often overlook how erosion simultaneously weakens the soil's inherent resistance (capacity) and degrades its current state (condition)-key drivers of long-term vulnerability and two core dimensions of soil security. To address this, we present a Capacity-Condition (CCF) framework, which quantifies erosion vulnerability using the erosion risk capability metric, which captures the gap between a soil's inherent resistance to erosion (capacity) and its erosion-altered state (condition). The framework employs the pedogeonon concept, identifying unique landscape units where the same soil-forming factors operate over time. Within each pedogeonon, two soil states are compared: genosoil (conditions influenced by natural erosion) and phenosoil (present state shaped by both natural and human-accelerated erosion). Capacity is assessed using genosoil indicators (clay ratio and topsoil thickness), and condition is evaluated using the phenosoil/genosoil ratio for the same indicators. Utility functions standardize these indicators on a 0–1 scale, enabling their aggregation into composite scores. When applied to New South Wales (NSW), Australia, the framework identified regions most vulnerable to erosion. Coastal areas and the upper northwest, characterized by intensive dry cropping and grazing on modified pastures, exhibited the highest risk values, indicating a lower capability to withstand future erosion. Conversely, regions with mixed land use-including grazing on native vegetation, intensive horticulture, and irrigated cropping-showed moderate risk, demonstrating the framework's utility for targeted, spatially explicit soil conservation and land management planning.</div></div>","PeriodicalId":48622,"journal":{"name":"International Soil and Water Conservation Research","volume":"13 4","pages":"Pages 771-794"},"PeriodicalIF":7.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulated rainfall experiments were conducted using lanthana (La&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;), yttria (Y&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;), and ceria (CeO&lt;sub&gt;2&lt;/sub&gt;) separately tagged Acrisols, Chernozems, and Arenosols at 10°, 15°, and 20° slope gradients under a 120 mm h&lt;sup&gt;−1&lt;/sup&gt; rainfall intensity. Sediment from different soils during 1-h (1 h) erosion process was continuously and separately collected within a 6-min time interval. Then, artificial mixtures were created using sediment from different soils over the same collection time. Sediment contributions were estimated using bulk samples (i.e., &lt;1000 μm) for REE tracing, while they were estimated using a series of particle size ranges (i.e., &lt;10, 10–63, 63–125, 125–250, 250–500, and 500–1000 μm) according to the composite fingerprinting for different source soil groups (i.e., Acrisols–Chernozems, Acrisols–Arenosols, Chernozems–Arenosols, and Acrisols–Chernozems–Arenosols). Here, we also analyzed the impacts of particle correction based on REE enrichment ratio (&lt;em&gt;ER&lt;/em&gt;) within fine particles (&lt;10, &lt;63, and 10–63 μm).

In this study, three recovery stages of tropical secondary forests (i.e. early recovery stage, middle recovery stage, late recovery stage), and old-growth forest were selected for comparison in tropical forests on Hainan Island. By using spatiotemporal substitution method, we investigated the variation of soil water retention in three recovery stages and old-growth forest, and revealed its dominant controlling factors. The results showed that 0–60 cm soil water retention was improved as recovery stage progresses. Specifically, the topsoil (0–10 cm) soil water retention in later stage almost could recover the level of old-growth forest, whereas the deep soil (10–60 cm) water retention may not recover the level of old-growth forest as recovery stage progresses. Additionally, the soil structure and soil nutrients also improve while the soil aggregates stability reduced as recovery stage progresses. Among these properties, total porosity was found to be the most important factor controlling soil water retention, accounting for 27.44 %, followed by bulk density (19.62 %) and capillary porosity (16.83 %), but soil particle size composition had a weakly effect on soil water retention.
