Abstract :The study was carried out in the natural pasture of the Savucak village of Karakoçan district in Elazığ province in 2021 and 2022. The aim of the study is to determine the macro element contents of the herbages of the pasture where five different nitrogen doses (0, 5, 10, 15, 20 kg da-1) and phosphorus (0, 4, 8, 12, 16 kg da-1) were applied. Calcium (Ca), magnesium (Mg), potassium (K) and phosphorus (P) levels were determined in the herbages cut from the pasture. The determination of Ca, Mg, K and P in dried and ground herbs was made by ICP-MS and the research was carried out in randomized blocks with three replications in accordance with a two-factor factorial experiment design. In the study, it was determined that the effect of increasing nitrogen and phosphorus doses on the macro element contents of pasture herbage was statistically significant. It was observed that Ca, Mg, K and P contents of pasture herbage decreased with the increase of phosphorus doses applied to the pasture, and macro element contents increased with the increase of nitrogen doses. It was determined that the Ca, Mg, K and P contents increased with the increase of the nitrogen dose, but the increase in the phosphorus ratio did not have any effect on the Ca, Mg, K and P contents of the pasture herbage. According to the results obtained from the research, it was concluded that 10 kg da-1 nitrogen and 4 kg da-1 phosphorus fertilization is appropriate in Elazig and pastures with similar ecologies.
