Soil animals, of which micro-arthropods constitute a high proportion, do not merely play a subsidiary role in the formation of different humus forms, but a most decisive one (Kubigna, 1955). Among the micro-arthropods, collembola are believed to play an important role in the breakdown of litter and humus (Schaller, 1950). Poole (1959) suggests that the direct value of collembola as litter feeders is probably small, judging solely from their gut contents, but, on the other hand, they must play sorne part both chemical and physical, in the breakdown of humus. He further states that their numbers and activity suggest that they may be of considerable importance. Dunger (1956) and Fourman (1938) are also of the opinion that collembola participate in the decomposition of falling leaves. [...]
