摘要

对全球人口增长的预测强调，迫切需要恢复退化的盐碱地，以满足对粮食、饲料和纤维日益增长的需求。本研究评价了石膏(G)、单质硫(S)、蚯蚓堆肥（VC）、生物炭(B)和微生物接种对土壤修复的单独和联合效应。基于13种土壤性质，建立了基于总数据集（CSDI- t）和最小数据集（CSDI- m）的综合土壤退化指数（CSDI）。所有处理均显著改善了土壤健康（p < 0.05）， G + VC和S + VC组合分别使CSDI-T降低84 - 85%和65 - 71%，CSDI-M降低84 - 87%和66 - 70%。土壤修复率与作物产量直接相关，CSDI模型解释了29 - 87%的小麦产量差异。这些研究结果表明，G/S + VC处理是一种具有成本效益、环境可持续的土壤修复和生产力提高解决方案，CSDI模型为评估土壤修复策略提供了强大的工具。

Integrated organochemical – Microbial solutions remediate degraded saline-sodic soils

Projections of global population growth underscore the urgent need to restore degraded saline-sodic soils to meet rising demands for food, feed, and fiber. This study evaluated the individual and combined effects of gypsum (G), elemental sulfur (S), vermicompost (VC), biochar (B), and microbial inoculation on soil remediation. A comprehensive soil degradation index (CSDI) was developed with total (CSDI-T) and minimum datasets (CSDI-M) using 13 soil properties. All treatments significantly improved soil health (p < 0.05), with G + VC and S + VC combinations reducing CSDI-T by 84–85 % and 65–71 % and CSDI-M by 84–87 % and 66–70 %, respectively. Soil remediation rates correlated directly with crop yield, with CSDI models explaining 29–87 % of the variance in wheat yield. These findings highlight G/S + VC treatments as cost-effective, environmentally sustainable solutions for soil restoration and productivity enhancement, with CSDI models offering robust tools for evaluating amendment strategies.

期刊介绍： The International Soil and Water Conservation Research (ISWCR), the official journal of World Association of Soil and Water Conservation (WASWAC) http://www.waswac.org, is a multidisciplinary journal of soil and water conservation research, practice, policy, and perspectives. It aims to disseminate new knowledge and promote the practice of soil and water conservation. The scope of International Soil and Water Conservation Research includes research, strategies, and technologies for prediction, prevention, and protection of soil and water resources. It deals with identification, characterization, and modeling; dynamic monitoring and evaluation; assessment and management of conservation practice and creation and implementation of quality standards. Examples of appropriate topical areas include (but are not limited to): • Conservation models, tools, and technologies • Conservation agricultural • Soil health resources, indicators, assessment, and management • Land degradation • Sustainable development • Soil erosion and its control • Soil erosion processes • Water resources assessment and management • Watershed management • Soil erosion models • Literature review on topics related soil and water conservation research
