It aimed to assess the impact of different crop establishment methods on system productivity, earthworm activity and diversity, and soil quality parameters for long-term sustainability. Three distinct crop establishment methods viz. zero-till direct-seeded rice (ZTDSR), conventional-till direct-seeded rice (CTDSR), and transplanted puddle rice (TPR), were employed in conjunction with various crop residue management strategies. The TPR and conventional tillage methods consistently outperformed ZTDSR in terms of grain yield and recorded a 28.9% and 15.4% higher grain yield than ZTDSR and CTDSR, respectively. However, TPR had a detrimental impact on the performance of all winter crops, resulting in a lower grain yield by 29% and 44% than CTDSR and ZTDSR, respectively. The incorporation of a legume or oilseed during the fallow period in the winter season in a rice-fallow system resulted in an increase in system productivity from 5.44 to 9.54 Mg ha⁻¹ (75% increase) demonstrating its potential to boost the food security of the region. Importantly, the study also quantified the critical role of conservation agriculture (CA) practices in enhancing soil health and earthworm activity. The CA-based production systems (CTDSR and ZTDSR) noted a 35.6%, 27.3%, 91.9%, and 73.4% higher earthworm casting, burrows count, total earthworm count, and biomass, respectively, over the TPR system. The TPR production system was associated with increased parameters of soil cracking, including length, width, depth, and volume compared to CA-based management systems. In conclusion, adopting CA-based practices and integrating short-duration pulses and legumes can enhance crop productivity, soil health, and earthworm populations, supporting food and nutritional security in India's rice-fallow regions and similar South Asian agro-ecotypes.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"53 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145117224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing evaluation frameworks often emphasize ecosystem structure and function while lacking integration with sustainable development goals (SDGs), thereby failing to reflect the coupled dynamics of ecological integrity, service provision, and socio-economic sustainability. To address this gap, this study aims to construct an integrated ecosystem health-service-sustainability (EHSS) assessment framework by incorporating SDGs into the vigor-organization-resilience-services (VORS) model in order to systematically evaluate the coupled dynamics of socio-ecological systems among ecological health, ecosystem services, and human well-being. This framework is applied to Qilian Mountain National Park (QLMNP) from 2000 to 2020 to investigate the spatiotemporal dynamics and driving mechanisms of EHSS. The results reveal a general spatial pattern of “higher in the east, lower in the west” and a temporal trend of “first increasing, then declining.” While township-level transitions were frequent, spatial clustering remained stable with notable local fluctuations. Using XGBoost–SHAP, we identify precipitation, temperature, and elevation as key drivers, with nonlinear and spatially heterogeneous impacts. Optimal recovery conditions occur below 3853 m elevation, with 451–639 mm of annual precipitation and temperatures ranging from −4.38°C to 5.10°C. These findings provide valuable insights for ecosystem restoration and sustainable development in fragile regions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"36 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145117192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In poorly structured sandy soil, modifying the mechanical composition may be a prerequisite for effective SOM management and crop yield improvement. This study investigated the effects of organic materials and introduced clay (Quaternary red clay soil with 38.5% clay) on soil water dynamics, maize growth, root morphology, and water use efficiency (WUE) in a sandy field soil (4.3% clay). The treatments included: control (CK), biochar addition (BC), lignite organic fertilizer addition (LG), and biochar and lignite organic fertilizer combined with introduced clay (BCR, LGR). Compared with CK, organic amendments alone (BC, LG) increased the silt + clay content (SC) and SOM content by 4.3%–5.8% and 5.3–9.2 g kg<jats:sup>−1</jats:sup> in the 0–20 cm soil layer (<jats:italic>p</jats:italic> &lt; 0.05), and improved grain yield (GY) and WUE by 19%–37% (1428–3312 kg ha<jats:sup>−1</jats:sup>, <jats:italic>p</jats:italic> &lt; 0.05) and 19%–41% (3.3–6.8 kg ha<jats:sup>−1</jats:sup> mm<jats:sup>−1</jats:sup>, <jats:italic>p</jats:italic> &lt; 0.05). The introduced clay (BCR, LGR) showed larger improvements: SC and SOM increased by 19.4%–21.2% and 7.0–11.0 g kg<jats:sup>−1</jats:sup>, and GY and WUE increased by 2385–5016 kg ha<jats:sup>−1</jats:sup> and 4.1–9.5 kg ha<jats:sup>−1</jats:sup> mm<jats:sup>−1</jats:sup>. Additionally, volumetric water content (VWC) was significantly linearly correlated with SC and SOM content (<jats:italic>p</jats:italic> &lt; 0.05). Sandy soil with an SC of around 16% exhibited reduced SOM decomposition and stable GY. PLS‐PM analysis indicated that WUE was mediated by VWC as an intermediate variable, whereas organic amendments alone had a limited direct impact on VWC.

However, in karst regions, evidence remains limited on whether—and by what mechanisms—biochar enhances soil fertility by reshaping bacterial diversity and co‐occurrence network structure. This study focused on karst yellow soil, conducting a two‐year natural monitoring experiment on runoff plots (2 × 1 m). The experimental design evaluated multiple factors: slope gradient (15°, 25°), biochar application time (1, 2 years), and application rates (B30 = 30 t/ha, B60 = 60 t/ha) to assess changes in soil fertility and bacterial community characteristics. In all treatments, biochar application improved soil fertility. The segmented structural equation model showed that under the 15° condition, fertility enhancement was mainly achieved by increasing bacterial diversity, while under the 25° condition, it depended on the bacterial network structure. During the initial application period (1 year), bacterial diversity regulated the effect, while with long‐term application (2 years), fertility improvement was unrelated to the microbial community. Interaction analysis showed that the amount of biochar added was the main factor for improving soil fertility in different treatments (<jats:italic>F</jats:italic> = 58.34). Increasing the amount showed a dose‐related improvement in fertility (<jats:italic>R</jats:italic><jats:sup>2</jats:sup> = 0.706, <jats:italic>p</jats:italic> &lt; 0.01), and different mechanisms were observed between different amount levels: at B30, bacterial diversity, network structure, and key species (<jats:italic>Actinobacteria</jats:italic>) had a significant impact on soil fertility, while at B60, biochar application mainly increased bacterial diversity index to improve soil fertility. These results established a functional chain connecting biochar application, microbial community regulation, and enhanced soil fertility in slope ecosystems. The demonstrated efficacy supported biochar implementation as a viable strategy for improving soil quality on sloping lands in karst regions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"88 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the responses of POC, MAOC, and their carbon (C) fractions to grassland degradation in Songnen grassland. Soil samples (0–10 cm depth) from a grassland degradation sequence including undegraded (NDG, <jats:italic>Leymus chinensis</jats:italic>), lightly (LIG, <jats:styled-content style=\"fixed-case\"><jats:italic>Puccinellia tenuiflora</jats:italic></jats:styled-content> and <jats:italic>Leymus chinensis</jats:italic>), moderately (MOD, <jats:styled-content style=\"fixed-case\"><jats:italic>Chloris virgata</jats:italic></jats:styled-content>), and severely (SEV, <jats:italic>Suaeda heteropteran</jats:italic>) degraded grassland were analyzed for contents of total organic C, labile C, and stable C in soil organic matter (SOM), and particulate (POM), and mineral‐associated organic matter (MAOM). Grassland degradation reduced the SOC content by decreasing both POC and MAOC content, primarily from the reduction in plant biomass and substantial soil erosion. The reductions in total C, labile C, and stable C contents resulting from grassland degradation in POM (61%, 54%, and 66%, respectively) were larger than those in MAOM (43%, 38%, and 47%, respectively), indicated that POM was more sensitivity to grassland degradation in comparison to MAOM. Grassland degradation increased the SOC stability because the larger reduction in POC than MAOC content decreased the ratio of POC/MAOC by 50% in degraded grasslands compared with NDG. The loss of SOC under MOD and SEV was mainly due to the higher C contents in MAOM than POM, which resulting in the contributions of MAOM to the loss of total C, labile C, and stable C in SOM were greater than that of POM. Concluding, grassland degradation decreased the SOC content by reducing both the POC and MAOC content because of low C input from plant biomass, and the reduction in MAOM was identified as the primary factor contributing to the SOM loss following grassland degradation due to the high MAOC content.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"7 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ecological risks were assessed using potential ecological risk index (<jats:italic>H</jats:italic>) and pollution load index (PLI). The results were: MPs abundance varied significantly with urban proximity and mulching duration, with the highest levels observed in exurban and short‐term mulched stands. Vertical distribution showed an initial increase followed by a decline with depth. MPs were mainly granular, gray in color, and primarily composed of polymethyl methacrylate and polyethylene terephthalate. Increased distance from urban centers and longer mulching durations led to reduced diversity in MPs morphology and polymer types, and a shift toward smaller particle sizes (50–100 μm), particularly in short‐term mulched plots. MPs particle size was negatively correlated with the proportion of soil microaggregates (<jats:italic>p</jats:italic> &lt; 0.05), whereas polymer types showed significant positive correlations with soil pH, total nitrogen, hydrolyzable nitrogen, total potassium, and large aggregate proportion (<jats:italic>p</jats:italic> &lt; 0.05), indicating that soil properties influence MPs distribution and composition.

A significant knowledge gap exists in quantitatively linking long‐term soil degradation processes to the decline in availability of key macronutrients in arid agroecosystems. This study integrates historical datasets (1975–2024), field observations, GIS mapping, and advanced statistical modeling to identify key chemical and physical soil degradation drivers and quantify their impacts on soil available nitrogen, phosphorus, and potassium in the eastern Nile Delta of Egypt, a key arid agricultural region facing severe land degradation. Results identified escalating soil salinity (EC +123%) and sodicity (sodic area: 276–1084 km<jats:sup>2</jats:sup>) as primary degradation drivers over five decades, alongside severe soil organic matter depletion (−33.9%) and reduced the stratification ratio of soil organic carbon (SR of SOC, calculated as the ratio of SOC concentration in surface to subsurface soil; −52.2%). The structural equation modeling and random forest analysis confirmed that reduced SOC SR and increased waterlogging lead to soil degradation via increasing salinity, exchangeable sodium percentage, and compaction (higher bulk density). As a result, a reduction in available nitrogen (−12.2%), phosphorus (−36.4%), and potassium (−11.2%) was recorded. Specifically, increased soil pH and bulk density reduced available phosphorus, while reduced SOC SR drove the reduction of available nitrogen and potassium. Consequently, the extent of areas classified as experiencing very high soil degradation more than doubled, expanding from 731 to 1760 km<jats:sup>2</jats:sup>. This study provides quantified evidence linking specific degradation drivers to nutrient declines in the Nile Delta, highlighting an urgent need for sustainable management (e.g., improved irrigation, organic amendments, and salinity control) to ensure agricultural sustainability.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"55 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
