摘要：Cover plants are intended to cover, protect the soil and provide straw for the Direct Tillage System (DTS), and are cultivated in areas that would be destined for fallow or prior to commercial crops. The use of these plants in the DTS in the Cerrado region can provide improvements in the physical, chemical and biological conditions of soils, as well as in the health and development of crops of economic interest. When choosing the cover plant for his area, the producer must choose species that meet his needs and that have good development in the region. There is a wide variety of species adapted to the Cerrado region, mainly from the grass or legume group, which can provide distinct benefits to the soil and commercial crops. The species also have different characteristics that can favor a better use of the resources of the environment, or have a synergistic effect on the benefits provided by the use of only one type of cover plant. Thus, the use of a mix of cover crops, especially with species that present contrasting characteristics, has been growing since they can provide greater benefits to the system than the cultivation of single species, such as greater availability of nutrients for crops and greater protection of the ground. Therefore, the use of cover crops, isolated or in a mix, is a great alternative to improve soil quality and benefit commercial crops in succession, which can contribute to the intensification of sustainable agriculture in the Cerrado.
