Abstract. The present work had as objective the verification of the effects of the incorporation of organic residues originating from ETE of the milk factory products in the soil and the effects in the development of the Brachiaria brizantha plants. The organic material was collected in the discard area of the factory, and been evaporated, triturated and separated in three granule size: powder, medium particles (with 2.0 mm diameter) and grains (medium particles with 6.0 mm diameter) and incorporate in soil by quantity of 0, 5, 10, 15 and 20 t. ha–1 followed by the planting of the forage. During the development of the plants, three cuts were appraised the dry weight and number of tillers. At the end, analysis of the fertility of soil was executing. The used experimental design was representing by randomized blocks with four repetitions. The application of organic material originating from ETE residual of dairies was have shown highly promising results vin the development of the forage plants, mainly when they are used in the powder form or attached and in higher amounts. Also considering some absorption by the plants during the experiment, the level of the nutrients and available minerals in the soil increased, except for the magnesium.
