The objective of this work was to evaluate the effects of the reutilization on the physical properties of different types of substrate used to grow cherry tomato, at Jaboticabal, São Paulo State, Brazil (21º14'05" S, 48º17'09" W). We used the split-plot experimental design with complete randomized blocks and four replications. In the plots were placed seven types of substrates, and in the subplots, three periods of physical characterization of the substrates. The seven substrates were prepared with different combinations of three materials: sand, crushed sugarcane and peanut bark. The physical properties evaluated were submitted to variance analysis and the averages were compared by the Tukey test, at 5% probability level. The reutilization of the substrate prepared with equal parts of the three components promoted the increase of bulk density and easily available water content, and the decrease of total porosity, aeration space, and remaining water content.
