Conservative agriculture is considered as an alternative to tackle the need for increased agricultural production based on sustainable agriculture activities with the aim of increasing production and product stability along with preserving the environment. Tillage is one of the most important factors affecting soil structure. Selection of appropriate tillage systems varies according to the conditions of each region, such as climate, soil type, type of plant residues, tensile strength and so on. Understanding the components of aggregate sustainability controller is very important for maintaining soil structure. This review paper discusses the role of tillage on aggregate stability and soil structure in order to reach conservative agriculture development. Considering the advantages of conservation tillage, it is better to use this kind of tillage for sustainable agriculture development. Based on the analysis of available literature, it can be concluded that Conservation tillage also enhances soil structural stability through its positive effects on soil moisture, organic matter. Less soil disturbance, which is the characteristics of conservation tillage, has positive effects on soil properties, soil processes which interact in a complex way and together, they all enhance soil quality.
