Abstract
The soil is considered a natural resource, becoming extremely important, as it has the ability to promote food production, being fundamental in environmental protection. Studies on soil quality have been increasingly frequent, for this evaluation, there is a wide and complex set of soil indicators that can be used. Thus, the objective of this literature review is to present a concise discussion about the concepts of soil quality and some indicators, emphasizing physical and chemical. The evaluation of soil quality, which is a combination of physical, chemical and biological properties that contributes to the understanding of the limits of each soil, as well as leads to clarify what are the necessary measures for its recovery in case of degradation. The way of cultivating the soil reflects the growing concern with environmental quality, with the preservation of life and the maintenance environmental conditions for future generations, which causes several changes in the way of cultivating the soil, with the objective of reducing human action on the environment, being possible its preservation. The selection of indicators is fundamental for the evaluation of soil quality. A good indicator should be able to reflect the functioning of the ecosystem, identify the forms of disturbances, be economically viable and have ease of monitoring. The physical and chemical indicators of soil quality allow the knowledge of a given site and the transformation process, thus contributing to the management to be adopted.
