Abstract

Recently, a lot of studies focused on the effects of biochar application to agricultural soils and its influence on the soil properties.However, only limited information is available on the simultaneous impact of N-fertilizer combined with biochar to soil physical propersies such as: soil moisture, soil temperature, bulk density and waterfilled 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, 1 st and 2 nd level of N fertilization).The results showed that the both biochar amendment and biochar with N fertilizer increased the soil moisture in the range of 1 to 15%, on average.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 (16.0) during the years of 2014-2016.A positive trend of water-filled pore space increase by the time in all studied treatments was observed.No significant changes in the average soil temperature were observed between the biochar and biochar with N fertilization treatments during the growing seasons of individual years.The higher rate of biochar resulted in lower soil bulk density in all treatments with biochar in combination with N fertilization in the following order: B0N1 (1.49) > B10N1 (1.47) > B20N1 (1.44) as well as B0N2 (1.51) > B10N2 (1.47) > B20N2 (1.39) during years the studied period (2014)(2015)(2016).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
