Abstrakt: Main sources of important nutritionally compounds - polyunsaturated fatty acids (PUFA) essential in soils animal diet were compared. The highest concentration of PUFA was found in cyanobacteria (namely Antarctic strain Pseudophormidium sp.), followed by fresh litter, algae, fungi and decomposed litter. The PUFA occurrence in bacteria including actinomycetes was rare. Leaf litter is the most important source of PUFA for soil invertebrates in regards to both PUFA concentration and occurrence in soil. The stage of litter decomposition significantly affected the content of all 13 detected PUFA. The total PUFA content decreased significantly during litter decomposition. Enrichment in certain PUFA was observed in the latest stages of litter decomposition, indicating that the soil microflora improves the nutritional value of the decaying ĺitter.
