This study compared the chemical and microbial properties of organic horizons and the uppermost mineral layers in mine soils under pure pine (Pinus sylvestris), birch (Betula pendula), larch (Larix decidua), alder (Alnus glutinosa), and mixed pine\u2013alder and birch\u2013alder forest stands. The studied properties included soil pH, content of organic C (Corg) and total N (Nt), microbial biomass (Cmic), basal respiration, nitrogen mineralization rate (Min-N), and the activities of dehydrogenase, acid phosphomonoesterase, and urease. Near-infrared spectroscopy (NIR) was used to detect differences in the chemical composition of soil organic matter under the studied forest stands. There were significant differences in Corg and Nt contents between stands in both O and mineral soil horizons and also in the chemical composition of the accumulated organic matter, as indicated by NIR spectra differences. Alder was associated with the largest Corg and Nt accumulation but also with a significant decrease of pH in the mineral soil. Microbial biomass, respiration, the percentage of Corg present as Cmic, Min-N, and dehydrogenase activity were the highest under the birch stand, indicating a positive effect of birch on soil microflora. Admixture of alder to coniferous stand increased basal respiration, Min-N, and activities of dehydrogenase and acid phosphomonoesterase as compared with the pure pine stand. In the O horizon, soil pH and Nt content had the most important effects on all microbial properties. In this horizon, the activities of urease and acid phosphomonoesterase did not depend on microbial biomass. In the mineral layer, however, the amount of accumulated C and microbial biomass were of primary importance for the enzyme activities.", "keywords": ["microbial biomass", "13.

The objective of this study was to assess the effect of texture of soil substrate and the planted tree species on microbial properties of mine soils reclaimed for forestry. Soil samples were taken from loamy sands and sands afforested with Scots pine and silver birch either in monocultures or in the mixed stands. The samples were measured for the contents of organic C (Corg), total N (Nt) and pH. The examined microbial properties included basal respiration (RESP), microbial biomass (Cmic), Cmic-to-Corg ratio, activities of dehydrogenase, acid phosphomonoesterase and urease and community level physiological profiles (CLPPs) studied using Biolog\u00ae Ecoplates. The loamy sands had higher pH, contained more Corg, Nt and Cmic and exhibited higher basal respiration and enzyme activities than the sands. However, their Cmic-to-Corg ratio was lower indicating less availability of Corg for soil microbes compared with the sands. The CLPPs in the loamy sands differed from those in the sands although there was no difference in microbial diversity (expressed as Shannon's diversity index) and activity on the Biolog\u00ae plates between the two textural classes. Tree species did not affect Corg, Nt and Corg-to-Nt ratio and had only a weak effect on CLPPs. However, the values of Cmic, RESP, Cmic-to-Corg ratio, dehydrogenase and urease activities were significantly lower under pine compared with the birch and mixed stands. The obtained results suggest that the texture of soil substrate is of higher importance for microbial properties of the studied mine soils than the planted vegetation.", "keywords": ["tree species", "microbial biomass", "enzyme activities", "CLPP", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.
