Soil is a dynamic and complex natural system, which is interactively regulated by physical, chemical, and biological properties and processes to provide ecosystem services including crop production. The soil quality as the critical component of the ecosystems is associated with soil's usefulness or performance to environmental quality as well as food quality. Soil quality is related to the development of many soil properties such as providing soil health, reflecting the fitness of a soil body, supporting water quality, sustaining plant productivity, and promoting human health. Soil is a sink for soil organic carbon (SOC). SOC, infiltration, aggregation, pH, microbial biomass, nitrogen forms, topsoil depth, conductivity or salinity, and available nutrients are the important indicators for soil quality. Mycorrhizal fungi also have an effect on soil quality in terms of increase in SOC, aggregation, nutrient uptake, and also increase in soil capacity for better health. The strength of the mycorrhizal association and its relationship with soil structure depends on root morphology and mycorrhizal hyphae. Arbuscular mycorrhizal fungi inoculation often increases the success of the ecological restoration as well. Mycorrhizal fungi are also effect on the soil function and capacity to increase productivity, resilience, and health functions. Also mycorrhizae increase SOC content, rhizosphere fertility, aggregation, porosity, and bulk density and reduce the stress factors that are all increase the soil quality.
