Degradation of soil resources is still the most serious and widespread threat to humankind. Soil has an important role to play in the global environment of food security, water security, climate stability, biodiversity, and ecosystem services (McBratney et al., 2014). Worldwide research has increased awareness that soil resources have influenced by human management and practices. Soil quality assessment provides a better understanding and awareness how soil resources are needed as an essential ecosystem services consisting of truly living bodies with chemical, biological, and physical properties (Karlen et al., 2003). Therefore, soil assessment is periodically needed to identify the condition of soil resources at all scales (Karlen et al., 2008). The soil science community has discussed for the past few decades about the definition of soil quality and a widely set of indicators, which are the physical, chemical and biological properties, has been identified as affecting soil quality (Andrews et al., 2003). A few years later, the discussion has focused on the idea of soil health in term of added soil organism properties. It has become a set of biological indicators while the measurement of soil microorganism will depend on the purpose of the…
