Land-use changes, global climate disruption and other human-induced disturbances have led to important variation in soil biodiversity. The impact of disturbance driven biodiversity changes on ecosystem functioning and ecosystem stability can be evaluated by studying their resistance and resilience. The concept of soil resilience in combination with resistance is presented as an important component of soil quality and a key element of sustainability. The indices that provide a relative quantitative measure of both resistance and resilience range between +1 to -1. Different mechanisms of microbial resistance and resilience include stress dormancy, adaptation, growth rate and dispersal. Development of soil resiliency levels based on land use for specific disturbances would be useful for long range planning and management.
