“…Thus, soil microbial communities play a critical role in ecosystem processes, such as carbon cycling, nutrient turnover, production of trace gases, or pollutant degradation [1]. Microbial activities, populations, and communities are governed by environmental variables, such as soil type and texture, temperature, moisture, or pH, and management practices such as cropping, fertilization, and type of ecosystem also affect soil microbial activities [19,5,6]. Nevertheless, scientists published many papers about the monitoring and impact of soil properties on the biological parameters of soil types in many regions of the world [20,17,12], but the soils the Slovak Republic have rarely been studied.…”

The aim of our work was to survey and state the representative values and range of the microbial biomass carbon (C mic ) and microbial respiration activities in arable soils of three types (Chernozem, Luvisol, Planosol) and in pasture grassland soil (Cambisol). In arable soils no significant differences between the soil types were found concerning the content of C mic . Way of soil use significantly influenced C mic with higher values on pasture grassland soil. In Cambisol, a relatively strong relationships between C mic and C org (r = 0.919) as well as between C mic and N tot (r = 0.922) were determined. The basal respiration (BR) was no affected neither by a soil type nor by a way of soil use. On all monitored sites microbes responded positively to the addition of glucose (potential respiration -PR), but the strongest response was observed on the soil types with good mineralisation ability, such as Chernozems and Luvisols. On pasture grassland soil, the substrate availability index (PR/BR) with values of 2.32 was observed, which is lower compared to 7.60 of arable soil. This fact to indicate that pasture grassland soil had more easy decomposable organic compounds than arable soils.Keywords: arable soil; pasture grassland soil; microbial biomass carbon; respiration. AbstraktCieľom našej práce bolo preskúmať a stanoviť reprezentatívne hodnoty a rozsah hodnôt uhlíka mikrobiálnej biomasy (C mic ) a respiračnej aktivity ornej pôdy troch pôdnych typov (černozem, hnedozem, pseudoglej) a pôdy pasienka (kambizem). V ornej pôde neboli zistené preukazné rozdiely v obsahu C mic medzi pôdnymi typmi. Spôsob využívania pôdy preukazne ovplyvnil C mic , s vyššími hodnotami pri pasienku. V kambizemi boli zistené relatívne silné vzťahy medzi C mic a C org (r = 0,919) a C mic a N tot (r = 0,922). Bazálna respirácia (BR) nebola ovplyvnená pôdnym typom ani spôsobom využívania pôdy. Na všetkých sledovaných stanovištiach mikroorganizmy pozitívne reagovali na prídavok glukózy (potenciálna respirácia -PR), ale najsilnejšia odpoveď bola pri pôdnych typoch s dobrou mineralizačnou aktivitou ako černozem DETAILNÝ ABSTRAKTUvedenou štúdiou sme zmonitorovali veľkosť uhlíka mikrobiálnej biomasy a respiračnú aktivitu v štyroch najrozšírenejších pôdnych typoch Slovenska využívaných ako orná pôda a pasienok. Medzi pôdnymi typmi hnedozem (8 lokalít), černozem (7 lokalít) a pseudoglej (6 lokalít) na ornej pôde sme v množstve uhlíka biomasy mikroorganizmov nezistili preukazné rozdiely (pseudoglej od 107 do 777, s priemernou hodnotou 456 µg C g -1 ; černozem od 146 do 802 s priemernou hodnotou 362 µg C g -1 ; hnedozem od 108 do 714 s priemernou hodnotou 257 µg C g -1 ). Avšak pri tomto type využívania pôdy bolo štatisticky preukazne nižšie zastúpenie uhlíka biomasy mikroorganizmov ako v pôde pasienka (kambizem od 1024 do 1592 s priemernou hodnotou 1294 µg C g -1 ). Bazálna respirácia (BR) nebola ovplyvnená pôdnym typom ani spôsobom využívania pôdy. Na prídavok glukózy (potenciálna respirácia PR) pozitívne reagovali mikroorganizmy zo všetkýc...

“…The evaluated variability of microbial biomass carbon and respiration activities in three of the most widespread soil types in Hyrcanian forest soils showed significant differences between them. Differences of C mic , C org , C mic /C org in different forest and soil type already reported [9,13]. Bauhus et al (1998) reported Both C mic and the C mic -to-C org ratio were significantly affected by stand age, tree species and soil type [6].…”

The aim of study was to evaluate the variation of soil microbial biomass carbon (C mic ) and microbial respiration (M R ) in three types soil (Chromic Cambisols, Chromic Luvisols and Eutric Leptosols) of mixed beech forest (Beech-Hornbeam and Beech-Maple). Soil was randomly sampled from 0-10 cm layer (plant litter removed), 90 soil samples were taken. C mic determined by the fumigation-extraction method and M R by closed bottle method. Soil C org , N tot and рН were measured. There are significant differences between the soil types concerning the C mic content and M R . These parameters were highest in Chromic Cambisols following Chromic Luvisols, while the lowest were in Eutric Leptosols. A similar trend of C org and N tot was observed in studied soils. Two-way ANOVA indicated that soil type and forest type have significantly effect on the most soil characteristics. Chromic Cambisols shows a productive soil due to have the maximum C mic , M R , C org and N tot . In Cambisols under Beech-Maple forest the C mic value and soil C/N ratio were higher compared to and 16.3 and 3.3, respectively). This fact might be indicated that Maple litter had more easy decomposable organic compounds than Hornbeam. According to regression analysis, 89 and 68 percentage of C mic variability could explain by soil C org and N tot respectively.

“…Quite a few publications also focused on biological properties of chernozems under different land use. (Stakhurlova et al, 2007;Blagodatskii et al, 2008;Polyanskaya et al, 2010). However, comparative analysis of soil gradient from natural to anthropogenic-transformed ecosystems (arable and urban) are still lacking (Chen et al, 2001;Vasenev et al 2012;Zhao et al, 2013).…”

The typical chernozems (Kursk region, Russia) in undisturbed (virgin and mowing steppe) and disturbed (pasture, black fallow, arable and including urban) ecosystems were studied. In each ecosystem and urban functional zone (recreational, residential and industrial) soil samples were collected in 3-5 randomly chosen locations from the depths 0-10, 10-50, 50-100 and 100-150 cm (total 124). In the collected samples soil microbial biomass (C mic ) was analyzed by substrate-induced respiration method and basal (microbial) respiration (BR) was measured. The ratio of BR / C mic = qCO 2 and portion of C mic in soil organic carbon (C org ) were estimated. In the soils (0-10 cm) under black fallow, arable and urban ecosystems the C mic content and C mic / C org ratio were almost two times less compared to undisturbed ecosystems. Reduction of Cmic, BR and C mic / C org and increase of qCO 2 value down the chernozem's profile was reported. The C mic stocks over the chernozem's profile were 2-4 times higher in undisturbed ecosystems than in disturbed ones. Topsoil 10 cm contributed to the major part of the total C mic and BR over the profile (41-79%). The excess of CO 2 production (BR) in urban soils was shown.
