The aim of this work was to characterize physically the combination of substratum components with cellulose residue. The research was conducted at Soil Physics Laboratory in UNESP–Campus de Ilha Solteira–SP. It was used three substratum component: sand, soil and organic compound (grass + manure decomposed by 90 days) and the cellulose residue. The experimental design was entirely randomized with eight treatments and three repetitions. The treatments were: T1 = pure celluloseresidue; T2 = residue + soil (1:1); T3 = residue + sand (1:1); T4 = residue + compound (1:1); T5 =residue + soil + sand (1:1:1); T6 = residue + soil + compound (1:1:1); T7 = residue + sand + compound(1:1:1) and T8 = residue + soil + sand + compound (1:1:1:1). It was analyzed macro and microporosity and total porosity, substratum density, particles density, container capacity, electric conductivity and pH. The pure cellulose residue presented all the physics recommendation for substratum to seedlings production. In relation to electric conduction it was recommended to mixture cellulose residue with soil and sand.
