健康的土壤对生态系统、经济和人口的健康至关重要。因此，人们普遍认为，土壤健康的重要性是量化，无论是评估和作为一种工具，以帮助指导管理战略。不太清楚的是，土壤健康实际上应该如何衡量，特别是考虑到土壤健康不仅仅是土壤物理和化学特性的产物。鉴于它们对土壤健康的许多方面的公认重要性，微生物和微生物过程通常被用作土壤健康的指标，地球仪上常规使用一系列不同的基于微生物的指标。不幸的是，我们认为，许多这些预先存在的微生物测量不容易解释，可能不一定提供可靠的推断土壤健康状况。在这里，我们回顾了用于评估或监测土壤健康的微生物指标，并讨论了与其使用相关的一些更广泛的问题。我们提供建议，以更有效地指导和改善如何微生物信息可以用来产生相关的和可操作的土壤健康评估。
Healthy soils are critical to the health of ecosystems, economies, and human populations. Thus, it is widely acknowledged that soil health is important to quantify, both for assessment and as a tool to help guide management strategies. What is less clear is how soil health should actually be measured, especially considering that soil health is not exclusively a product of soil physical and chemical characteristics. Given their well-established importance to many aspects of soil health, microbes and microbial processes are often used as metrics of soil health with a range of different microbe-based metrics routinely used across the globe. Unfortunately, it is our opinion that many of these pre-existing microbial measurements are not easy to interpret and may not necessarily provide credible inferences about soil health status. Here we review the microbial indices used to assess or monitor soil health and discuss some of the broader issues associated with their use. We provide recommendations to more effectively guide and improve how microbial information could be used to yield relevant and actionable assessments of soil health.
