• Abstract:

  The no-tillage system is defined as a conservationist management system, which involves techniques with the objective of physical, biological and chemical soil conservation, based on the absence of disturbance and permanent soil cover through crop rotation. With this, this work aims to gather information obtained through bibliographic reviews that are associated with the physical quality of the soil under the no-tillage and conventional system. The no-tillage system has improvements in soil physical attributes such as reduced penetration resistance (Rp) by improving soil aggregates, soil density (Ds), mycopores and macropores, as there is no greater soil disturbance during use. of the system, thus increasing the oxidation of organic matter, which, consequently, favors the increase in C stocks, Power Mean Diameter (MPD). Differing from the conventional planting system, which has greater traffic and soil disturbance, thus breaking more the structure of the aggregates, reducing soil moisture because there is no deposit of cultural residues and greater resistance to penetration by soil compaction by the weight and use of agricultural machinery.
