Nitrogen fertilization (N) is commonly known as a main source of direct nitrous oxide (N2O) emission from agricultural soils. An area of 38 % of the total land surface of Poland was covered by agricultural soils in 2009. In this paper, we aimed at analyzing data regarding the land exploitation for 13 selected subareas of Poland between 1960 and 2009. Seven out of the 13 subareas studied are located in the West (area A), and six subareas are located in southeast of Poland (area B). The total area covered by large farms (> 20 ha) differed largely, between area A (10.6 %) and area B (0.9 %) in 2009. Both areas varied in terms of the amount of fertilizers used annually, average crop yield and crop structure. Average direct emissions of N2O from agricultural soils were 1.66 +/- A 0.09 kg N2O-N ha(-1) a(-1) for area A, 1.39 +/- A 0.07 kg N2O-N ha(-1) a(-1) for area B and 1.46 +/- A 0.07 kg N2O-N ha(-1) a(-1) for the whole country between 1960 and 2009.
