Applying cattle manure (CM) based on the N content often leaves excess P in the soil because of the differences in the N:P ratio in manure and that required by the plant. We evaluated the effects of CM application strategies on bahiagrass (Paspalum notatum L. Flugge) dry matter yield (DMY) and P leaching on a Florida Spodosol. The treatments were 200 and 400 kg N ha-1 from CM or 50/50 CM and ammonium nitrate (AN) combination, annually applied either in single or split dosage. Bahiagrass was clipped at 28-d intervals for DMY determination. Soil samples were taken from the Ap (0-15 cm), E (16-60 cm), and Bh horizons (61-120 cm) after each growing season to determine soil P status. At any given N rate, bahiagrass yield was greater for the CM+AN treatments compared to CM applied alone. Soil P concentration in the Ap horizon for the CM treatments were 64 and 54% greater than the CM+AN treatments in 2005 and 2006, respectively. No significant leaching of P into the E and Bh horizons occurred in 2005; however, P leached into the E horizon in 2006 with the CM treatments having greater P concentration compared to the CM+AN treatments. Soil P storage capacity which is an estimate of the capacity of a soil to retain additional P was exceeded in the Ap and E horizons over the study period. Combining CM+AN provided greater forage yield and may reduce P risk to surface and groundwater. Keyword: manure rates; nitrogen; ground water; Paspalum notatum
