Abstract in Polish

Pages 825-837 ; 27 cm

Analysis concerned the carbon content, main fractions of soil humus, total nitrogen content and contents of selected exchangeable elements (P-PO4, K, Ca, Mg and Mn) in the casts produced by earthworms, and in the upper layers of the soil, on several leys and permanent meadows. The percentage contents of C, fulvic acids and humic acids are always higher in casts than in the soil and rise along the sequence from younger to older meadows. The content of total nitrogen is also clearly greater in earthworm casts than in the soil and the C/N ratio rises along the sequence to older meadows. Exchangeable elements other than manganese show similar trends. It is shown that these trends probably result from changes in the proportions of two dominant species of Lumbricidae with alternate feeding specializations, namely the geophagous Aporrectodea caliginosa (Sav.) and the detritivorous Lumbricus rubellus Hoffm.
