ABSTRACT Alkaline soils present large amounts of calcium carbonates, with precipitation of insoluble calcium phosphate. The objective of the research was to determine the effects of the P application on the nutrient levels of the foliar tissue of Pennisetum pastures in calcareous soils in Córdoba-Colombia. Soil samples were collected from two locations in the Department of Córdoba. A completely randomized design with a 2 x 3 x 6 factorial arrangement (Vista Hermosa and Carolina), there Pennisetum species (king grass, Cuba OM-22, and Pennisetum purpureum), and six P doses (0, 80, 150, 250, 400, and 650 kg ha-1), applied as P2O5, was used. The addition of P did not increase the contents of N, K, Ca, and Mg in the king grass, Pennisetum purpureum, and Cuba OM-22 pastures. However, in the calcareous soils of Carolina, king grass, Pennisetum purpureum, and Cuba, OM-22 absorbed higher amounts of P.
