Abstract: An enormous ecological threat, soil pollution or soil contamination, has a significant negative influence on human wellbeing, agricultural productivity, and environmental balance. The loss of soil productivity brought on by the presence of soil contaminants is known as soil pollution. As a result of the addition or removal of components and compounds that harm plants, soil quality, and groundwater quality, soil becomes contaminated. The soil may be contaminated or polluted by both human activity and natural processes. Chemicals including pesticides, herbicides, ammonia, petroleum hydrocarbons, lead, nitrate, mercury, naphthalene, and other substances in excess can cause soil pollution. It reduces soil fertility, nitrogen fixation, erodibility, imbalances in the soil's fauna and flora, ecological imbalances, pollutant gas emissions, increased salinity, obstructions in drains, problems with public health, and contamination of sources of drinking water. Physical, chemical, and biological traits, actions, and features that can be quantified to track soil changes are known as soil quality indicators. To concentrate conservation efforts on preserving and enhancing soil quality, assess soil management practises and procedures, compare soil quality to that of other resources, and gather the necessary data to identify trends in the nation's soil health, soil quality indicators are crucial. So, this paper's goals are to examine recent efforts to define soil quality, discuss the variables and processes that affect soil quality, identify the soil and crop management methods that have an impact on these processes, and present a method for assessing soil quality.
