The effects of fertiliser application, recultivation type and site age on chemical and microbiological soil properties were examined on a short-term (1year) experimental trial situated on spoil heaps in Sokolov mining district, Czech Republic. Treatments at the site included fertilisation by inorganic form of nitrogen, concretely calcic saltpetre (N) and fertilisation by inorganic form of phosphorus, namely superphosphate (P). Plots were either fertilised in the beginning of growing season or unfertilised. Microbial biomass-C increased as a consequence of both N and P addition while comparing with control. There was a significant effect of fertilisation on non-fumigated C representing labile source of carbon. With N,P application non-fumigated C significantly decreased. Specific respiration rate calculated as basal microbial respiration to microbial biomass-C was significantly increased by fertiliser application. In contrary, no significant treatment effect on the other parameters include water extractable carbon, total C, total N, available P, soil pH and basal respiration was recorded. The results indicate that short-term fertilisation is not able maintain soil condition. Therefore, site age or recultivation treatment had significant effect on mostly investigated parameters (WEC, total C) rather...
