However, the increasing need for food security and the growth of industrial urbanization have led to soil pollution posing a significant threat to soil health, the environment, and public health. This study investigates the effects of heavy metals on plant anatomy, physiology, and morphology, focusing on how these metals displace essential nutrient uptake. Despite considerable research on soil contamination, gaps remain in understanding the mechanisms involved in heavy metals influencing plant health and the soil properties that govern their transformation, transport, and bioavailability. This study addresses these gaps by examining the impacts and mechanisms of heavy metal contamination on plant growth and identifying soil conditions that can mitigate contamination risks and remediation mechanisms. Through a comprehensive analysis, this study finds that heavy metals displace essential metal ions, inhibiting enzyme activity and disrupting critical processes. High concentrations of heavy metals produce free radicals and reactive oxygen species (ROS) in plant cells. This results in uncontrolled oxidation and the initiation of chain reactions with cellular biomolecules, causing oxidative stress and cellular damage. Additionally, this study highlights phytoremediation, bioremediation, and biochar as potential frameworks for remediating heavy metals contamination in agricultural soils. It proposes recommendations for future research to understand the synergistic effects of combining phytoremediation, bioremediation, and biochar which could lead to comprehensive soil remediation frameworks that are both economically feasible and environmentally friendly.</div></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"18 ","pages":"Article 100178"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite extensive literature documenting these benefits, there is a lack of comprehensive reviews that consolidate the findings, hindering the broader adoption of effective practices. This review examines the impact of cover crops on key soil properties, including bulk density (BD), saturated hydraulic conductivity (Ksat), organic matter (OM) content, pore size distribution, and water infiltration. A total of 190 studies from various countries, climatic zones, and agricultural practices were analysed, with the majority of data originating from 2–3-year studies conducted in the USA. The findings reveal that cover crops reduce soil bulk density by 1–24 %, increase organic matter by 7–74 %, enhance macropores by 1–67 %, and improve water infiltration rates by 5–629 %. Additionally, cumulative infiltration rates increased by 29–170 %, and Ksat was elevated by 10–627 %. Long-term studies (spanning 15 to 34 years) indicated even greater improvements in Ksat and soil porosity. Overall, cover crops were found to enhance soil organic matter, hydraulic properties, and overall soil condition, thereby contributing to sustainable crop production across a range of climatic, soil, and management conditions. Long-term research is necessary to better understand the impact of cover crops on soil properties, nutrient availability, crop performance, and environmental outcomes, which will inform the development of optimal soil-site-climate specific cover crop management practices.</div></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"18 ","pages":"Article 100177"},"PeriodicalIF":0.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a quantifiable framework integrating soil connectivity with the broader assessment framework has been lacking.

Using an online self-evaluation tool, the framework was applied to Australian land managers, focusing on the connectivity of two soil functions and six soil threats. The framework includes: utility graphs for each indicator; a method for nuanced interpretation of each soil role and connectivity indicators; spatial components; and automatic feedback to stakeholders. Our results indicate that knowledge indicators are consistently high across the country, while attitude utilities vary most and are often lowest; education had no effect, and younger stakeholders stood out for significantly lower, though still high, utility values. The study also identifies specific soil roles which require strengthening in different geographic regions. Despite the generally high levels of connectivity, the threat to soils by salinisation emerges as the soil role with the lowest connectivity utility. However, no significant correlation was found between the threat to soils by salinisation utility values and stakeholders' age or educational level, suggesting that other factors, possibly spatial or environmental, are more important. This study displays the importance of assessing knowledge, action, and attitude indicators when assessing connectivity and obtaining spatial information for spatial analysis.</div></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"17 ","pages":"Article 100175"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143172389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To comprehensively investigate the heavy metal contamination in farmland soils caused by mining activities and the impacts on soil microbial communities and functions, we collected 87 soil samples from farmlands near 29 mining sites nationwide, measured levels of cadmium, lead, copper, and zinc. Our findings revealed that 75.8% of the sampled farmlands exhibited varying degrees of heavy metal pollution. Cadmium contamination stood out, being 2.84 to 5.35 times higher compared to other metals. This pollution notably decreased microbial diversity in agricultural soils (P ≤ 0.04), causing a shift from intricate interconnected microbial co-occurrence modules to a higher number of simpler ones, indicating a fragmentation of the microbial interaction network. Additionally, heavy metal contamination led to a 10.9% increase in the importance of the heterogeneous selection process in community assembly. Despite reduced microbial alpha diversity, we observed an increase in the diversity and abundance of metal resistance genes (MRGs) and intensified microbe-MRG interaction. This suggests that microbial communities, even when altered, maintain functionality through enhanced redundancy, which probably facilitates the preservation of microbial activities. We also identified key taxa with intense connectivity in the microbial interaction networks, 58% of which have been recognized in previous studies for their predictive effects on soil health. These findings offer important insights for developing strategies to enhance soil health, such as promoting the presence of \"super-connectors\" in microbial networks for the maintenance of microbial community.</div></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"17 ","pages":"Article 100173"},"PeriodicalIF":0.0,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the medium-term (5–7 years) economic impact of cover crop adoption using plot-level data from field experiments in the state of Maryland. The empirical analysis employs ordinary least squares (OLS) statistical models and partial budgeting techniques to achieve the study objective. Our results show that cover crops do not have a statistically significant effect on crop yield, fertilizer costs, or pesticide costs, but we find that cover crop use statistically increases field operation and seed expenses. As a result, the private net return from cover crop adoption in the medium term is generally negative based on the Maryland field trial data used in the analysis. Specifically, the average net return per acre with cover crops is approximately $60-$90 lower for corn and around $60 lower for soybeans compared to fields without cover crops. This empirical finding suggests that public support through incentive payments may help further incentivize cover crop adoption in the US, which can then provide environmental and ecosystem services that are of benefit to the general public.</div></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"17 ","pages":"Article 100170"},"PeriodicalIF":0.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142420422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
