| Description
| - 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 the effect 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 NPK (in the ratio 1:1:1) were applied there and into V4, dose 30 g of compost were applied. The significant differences (P < 0.05) in the detection of Nmin, values of Ksat and SIR were found. The highest decrease of mineral nitrogen leaching was observed by the simultaneous applications of compost (V4) to arable soil, about 50% in comparison with the variant V4 (application of mineral fertilization) and about 10% in comparison with the control. Variants with addition of compost (V2 and V4) showed higher values than variants without, which were measured at three stages (before application of Nmin - 12 days after establishment of the experiment, after application of Nmin - 34 days, at end of the experiment - 63 days). During the experiment, two types of respiration were measured: BR and SIR.
