Two experiments were conducted with the objective of evaluating the influence of Si and P application upon organic and inorganic P forms in two soils solos: classificação da FAO e Soil Taxonomy (Orthic Quartzarenic Neosol – RQo- and Dystroferric Red Latosol – LVdf), having contrasting texture and mineralogy, before and after rice cultivation. The experimental was in a 4 x 3 factorial scheme, being four P doses and three Si doses. The phosphated fertilization altered the P labile forms, while in the case of low labile P forms the behaviour was dependent upon soil texture and mineralogy. The application of Si was shown to be promising to increase the availability of P for plants in rice.
