Sisal plants were cultivated in washed sand during twenty-one months. The plants were irrigated with complete nutrient solution and solutions with absence of each macronutrient (N, P, K, Ca, Mg e S). The plants, in the absence of each macronutrient, showed typical symptoms which were related to the low level of the respective element in the leaf. The growing of the leaves was reduced by the absence of the macronutrients.
