Influence of different type of fertilization and rainfall variations on soil hydrophobicity and leaching of mineral nitrogen

Popis výsledku v původním jazyce

This work deals with the influence of different type of fertilization and rainfall variations on soil hydrophobicity and on leaching of mineral nitrogen (Nmin). This influence was tested by the pot experiment. Deschampsia caespitosa was used as a model plant. The leaching of Nmin was measured by application of ion exchange discs and soil hydrophobicity was determined based on the values of saturated hydraulic conductivity (Ksat). Three groups of the treatments with different regime of irrigation and fertilization were prepared. The significant differences in the detection of Nmin and values of Ksat were found. All variants with addition of compost (Cp) showed lower amount of Nmin loss than variants without. The highest values of Ksat were found in variants with addition of Cp in comparison with variants where Nmin was applied. Low values of Ksat in variants with Nmin addition indicate an increased level of hydrophobicity.
