Abstract	Phosphorus is considered an essential element for plants, but it is found in low amounts in Brazilian soils, mainly in areas destined to pastures, and the application of organic matter contributes to the improvement of physical, chemical and biological soil attributes. The research had the objective of evaluating the application effects of the Bokashi organic compound on soil macro and micronutrients contents and leaves, as well as on Brachiaria brizantha cv. Marandu dry mass yield, evaluating the potential of the organic fertilizer as phosphorus source, in comparison with conventional chemical fertilizers. Different organic compound doses supplied the soil with 17 kg P 2 O 5 ha -1 , 34 kg P 2 O 5 ha -1 , 68 kg P 2 O 5 ha -1 , 136 kg P 2 O 5 ha -1 , and 204 kg P 2 O 5 ha -1 , comparing it with the conventional chemical fertilizer and the control. The results revealed that the organic fertilizer Bokashi can adequately replace the conventional chemical fertilizer of Brachiaria brizantha cv. Marandu, supplying the soil and plant with appropriate nutrients levels and maintaining the dry mass yield. KEY-WORDS: Organic matter; organic fertilizers; plants mineral nutrition; Bokashi .
