title: Contents, accumulation and release of energy in green, dead and decomposing plant materials in an upland grassland near Kamenicky, Czechoslovakia.
abstract: The energy content was studied in above-ground live plant material and in litter in a natural grassland ecosystem with dominant Nardus stricta L., defined phytosociologically as Polygalo-Nardetum strictae. PREISING 1950 corr. OBERDORFER 1957, and in two of its fertilized variants in the course of 1975 to 1977. Based on the determined production characteristics and data on decomposition processes, the amounts of energy accumulated by the green parts of the stands and the amount of energy released during decomposition from the litter were calculated. Changes in the energy content of litter in different stages of decomposition were determined. With progressing decomposition the energy content per gram ash-free decomposing plant litter increases.
