    Publicado 2018
    “…According to the results obtained, it was found that the use of the aerating roller had beneficial effects due to the fact that the treatments showed better conditions in the layers from 0 to 15 cm deep, making the nutrients available to the plants, however, a cyclic use is recommended since over time the nutrients show a lower availability, as it was shown by the comparison of means between the control and the other aeration roller treatments, where it was found that the 9 application of this implement had better results in Ra11, which was one of the most recent applications in the study area.…”
