摘要
土壤健康对农业可持续性至关重要。促进和维持土壤健康管理具有挑战性,因为它涉及许多相互依存的组成部分和步骤,而且是一个反复的过程。在此,我们提出了土壤健康循环(SHC)作为土壤健康管理循环,其中包括人的因素、管理实践及其对土壤健康指标(SHIs)的影响,从而对土壤功能产生后续影响。SHC 提供了一个结构,用于反复测试各种变化,以改善土壤健康。我们还使用 Web of Science 数据库对研究出版物进行了系统性审查,并辅以 Elicit AI 和 Scopus API 搜索,以确定将 SHIs 与土壤功能结果(SHC 的重要组成部分)联系起来的研究报告的状况。审查的重点是 2000 年至 2022 年期间的出版物,并强调大多数土壤健康研究都单独报告了覆盖种植、免耕或减少耕作、轮作和作物-牲畜一体化等土壤健康实践在改善 SHIs 或土壤功能结果(如生产力和可持续性)方面的潜在作用。如果能将这些方法与生产率、环境质量和盈利能力等土壤功能结果明确联系起来,就能提高人们对这些方法改善 SHI 的因果关系的信心。提出这样的证据可能会让我们将混杂因素区分开来,并根据具体情况推荐土壤健康做法。它还将通过知情、有益的政策和激励措施,影响特困地区的人文因素。
Soil health is pivotal to agricultural sustainability. Promoting and sustaining soil health management is challenging since it involves many interdependent components and steps and is an iterative process. Herein, the soil health cycle (SHC) is proposed as a soil health management cycle encompassing human dimensions, management practices, and their effects on soil health indicators (SHIs), leading to subsequent impacts on soil functions. The SHC provides a structure for an iterative testing of changes to improve soil health. A systematic review of research publications was also conducted using the Web of Science database supplemented by Elicit AI and Scopus API searches to determine the status of research reports connecting SHIs to soil function outcomes, a critical component in the SHC. The review focused on publications from 2000 to 2022 and highlighted that most soil health studies separately report the potential roles of soil health practices such as cover cropping, no-tillage or reduced tillage, crop rotation, and crop–livestock integration in improving SHIs or soil function outcomes such as productivity and sustainability. The confidence in the causality of improved SHIs due to practices can be increased by demonstrably linking them to soil function outcomes such as productivity, environmental quality, and profitability. Presenting such evidence might allow us to tease confounding factors apart and present and contextually recommend soil health practices. It will also affect the human dimension in the SHC through informed and beneficial policies and incentives.
