Abstract: The main expectation for using leguminous plants in pastures is improving animal production and reducing production costs. This research was carried out in a greenhouse, in order to evaluate the effect of two soil acidity correctives and P rates on P, Ca, Mg, Si, raw protein (RP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility (IVDMD) contents of Stylosanthes guianensis cv. Mineirão. A randomized blocks design was used in a 5x2 factorial arrangement, with five P rates (50 mg dm-3, 100 mg dm-3, 200 mg dm-3, 400 mg dm-3, and 800 mg dm-3 of soil) and two soil correctives (lime and Ca and Mg silicate), with three replications. Both lime and silicate applications, previously to the phosphate fertilization, assured P, Mg, Ca, RP, NDF, and ADF contents, in plants of Mineirão, compatible with good performances of grazing animals. The increase in the silicon content in Mineirão, resulting from silicate application, did not reduce the IVDMD. The substitution of lime by Ca and Mg silicate did not affect the nutritional value of the Mineirão subjected to phosphorus rates.
