|Title: COMPARISON OF VARIOUS METHODS OF CELLULOSE DECOMPOSITION MEASUREMENT APPLIED IN POST-MINING SOILS CHRONOSEQUENCE|
|Author: JAN FROUZ, MICHAL HOLÁSEK, MONIKA ŠOURKOVÁ|
|Abstract: Four method of cellulose decomposition measurement: filter-paper filled litter bag, cotton
filled micro containers, tension strength of cotton strip, and pressure strength of cellophane
film were compared in laboratory using the soil from four sites reclaimed after brown coal
mining by planting alder 4, 20, 22 and 32 years ago, and from one semi-natural alder forest
in the vicinity of the post-mining sites. Additionally, microbial respiration with and without
cellulose addition was measured. Except for cellophane film, all methods gave similar
results. A rapid increase in cellulose decomposition rate was observed in initial stages of soil
development during first 20 years after the alder trees were planted. Lower cellulose
decomposition rate was found in older plantations and in the control semi-natural forest.
Microbial soil respiration showed the same pattern as cellulose decomposition activity and
peaked in 20 years old reclamation. However, older sites displayed a higher relative increase
in respiration when cellulose was added, no such increase was observed in younger sites.
