The paper presents the results of a laboratory experiment aimed at the assessment of N2O emissions, NO3-, NH4+ and carbon (C) leaching from agricultural soils subjected to long-term mineral and organic fertilization. Our results show that long- term treatment impacts the N2O emissions from loamy-sand Luvisols to a greater extent than the recent single application of mineral or organic fertilizers. The N2O fluxes from soils with higher C-org content that results from long- term organic fertilization exceed those from soils with lower Corg content subsequent to long- term mineral fertilization. Our research confirms previous reports that the intensity of N2O emission is related to soil moisture. The NO3- leaching depended on the recent application of fertilizers with a stronger influence of single application of NH4NO3 than farmyard manure. Long-term fertilization did not impact the NO3- leaching.
