ABSTRACT
In the article the variables directly related to agricultural nitrous oxide emissions in Poland were studied. Based on a linear regression the model was created to describe the analyzed variables. As a result of Pearson's test and Shapiro-Wilk the variables which did not fulfill the tests assumptions were eliminated. In the resulting linear regression model, 63% of the variability of N2O emissions is explained by variability in use of nitrogen fertilizers. The study was conducted using the statistical package R-Project.
