土壤是陸地農業生態系統的重要組成部分，因而土壤質量或土壤健康成爲農業可持續發展的重要內涵。在以往的研究中，人們一直強調以土壤理化特性作爲持續性指標，但近期國際上關於土壤生物學參數的研究日漸增多，一些參數作爲生物指標已表現出很大的潛力，研究空間不斷擴展。對農業生態來說，土壤生物指標有可能成爲系統穩定性的早期預警和敏感指標。

Soil is a resource critical to the maintenance of any terrestrial ecosystem that we need to manage effectively. Thus soil quality or health, which consists of the chemical, physical and biological components of a soil and their interactions, is an issue that needs to be included in discussion of sustainability. The major emphasis has been on the use of soil chemical and physical attributes as indicators of sustainability. Investigations on biological parameters are increasing. Soil bioindicators are showing great potential to become the early warning and sensitive indicators of the stresses or perturbations in soils of agricultural ecosystems.
