摘要：During the last time a lot of studies focused on the effects of biochar application to agricultural soils and its effect on the soil properties.However only few information is known about the simultaneous impact of N-fertilizer combined with biochar to soil physical propersies such as: soil moisture, soil temperature, bulk density and water filled pore space.Therefore the aim of this study was to evaluate the changes in the soil physical properties of a silty loam Haplic Luvisol affected by the biochar application and its combination with N fertilizer during the years 2014-2016 (Experimental site of SUA-Nitra, Dolná Malanta, Slovakia).The field experiment was carried out in 2014 with different biochar application doses (0, 10 and 20 t ha-1) and different rate of N fertilization (0, 1st and 2nd level of N fertilization).The results showed that the both biochar amendment and biochar with N fertilizer increased on average the soil moisture in range of 1 to 15%.The higher rate of biochar resulted in higher soil moisture in all treatments with biochar in the following order B0 (14.9) < B10 (15.1) < B20 (16.2) as well as in biochar in combination with N fertilization: B0N1 (14.6) < B10N1 (15.7) < B20N1 (16.2) as well as B0N2 (14.8) < B10N2 (15.8) B20N2 (1.39) during years the studied period (2014-2016).
