Influence of fertilization on microbial activities, soil hydrophobicity and mineral nitrogen leaching

Popis výsledku v původním jazyce

This work presents the analysis of the influence of compost and reclamation substrate addition and mineral fertilizers application on leaching of mineral nitrogen, microbial activities, soil hydrophobicity and plant biomass production. To demonstrate theeffect of compost, reclamation substrate and mineral nitrogen (Nmin)addition on above parameters, the pot experiment was performed. As a model crop, Deschampsia caespitosa L. was used and cultivated for 63 days in climate chamber. The leaching of Nmin was measured by application of ion exchange discs, soil hydrophobicity was determined based on the values of saturated hydraulic conductivity (Ksat)and microbial activity was expressed as basal (BR) and substrate induced respiration (SIR). Four variants(V1-V4) with different doses of fertilizers were prepared: V1 - control without addition of fertilizers, V2 - this variant of experiment was prepared as mixture of compost and arable land in ratio 7:3, V3 - 90 g/m2 of mineral fertilizers NP
