With the objective of evaluating the progress of absorption of macro and micronutrients in cauliflower cultivated in substrate, an experiment was conducted in a greenhouse at the Universidade do Estado de São Paulo, in Jaboticabal, Brazil. The experimental desing used was randomized blocks, with six treatments and five replicates. The treatments comprised times of sampling (20; 30; 40; 50; 60 and 70 days after the transplant). The composition and accumulation of the macro and micronutrients of the shoot and root were evaluated. The biggest demand of nutrient happened in the period of 60 to 70 (DAT) for macro and micronutrients. The decreasing order of the macronutrients accumulated by the cauliflower was K, N, S, P, Mg and Ca and for micronutrients Fe, Zn, B, Mn and Cu.
