Box plot for the physical variables of the soil in the different management systems used in the experimental area.

CTCC = Conventional tillage with cover crop, MTCC = Minimal tillage with cover crop, CTWC = Conventional tillage without cover crop, MTWC = Minimal tillage without cover crop. Sm = Soil moisture, St = Soil temperature, MDA = Mean diameter of the aggregate, Macro = Soil macroporosity, Micro = Soil microporosity, TP = Total porosity, Bd = Bulk density, PR = Penetration resistance, Ts = Tensile strength of the aggregate.
