Effects of Invasion of an Aspen Forest (Canada) by Dendrobaena Octaedra (Lumbricidae) on Plant Growth

“…ever, the earthworms presumably caused major changes in the composition of the indigenous soil fauna and microflora and may have affected nutrient cycling and plant growth in this ecosystem. Earthworms are major soil-forming agents (Kubiena 1948, Bal 1982 and it is well known that earthworm activity may result in an increase in nutrient cycling (Lee 1985, Scheu 1994) and plant growth (Stockdill1959, Hoogerkamp et al 1983.…”

Notes on the Soils of Syria

“…The real roblem of these red soils on limestone would then appear Kubiena (1948) states that the iron oxide occurs in a highly dehydrated form and our X-ray data for the clay shows the presence of haematite, but not in very large amount (c. 5 per cent. of the z p clay).…”

“…It would seem that one of the more hydrated or less well crystallized members of the kaolinoid group can be taken as fairly characteristic of these red limestone soils. I n general it appears that the processes leading to the formation of terra rossa are not dissimilar to those giving brown forest soils, and in fact Kubiena (1948) has suggested that they should be regarded as the end member of the sequence rendzina-brown forest soil-terra rossa. Decalcification proceeds from the beginning, and under forest the initial shallow soil would certainly be dark brown to black in colour.…”

Evaluation of Kubiëna’s contribution to micropedology. At the occasion of the seventieth anniversary of his book “Micropedology”

“…OF SOIL CLASSIFICATION Studying the genesis and classification of soils, Kubiëna realised that each soil type has a distinct microfabric that he summarised in one term (Kubiëna 1948(Kubiëna , 1952(Kubiëna , 1970. A discussion of his work in the field of genesis and classification is however outside the frame of this paper, but it is clear that his micromorphological concepts cannot be considered isolated from the genetic and taxonomic ones.…”
