The rhizosphere of white spruce.

, : The rhizosphere of white spruce.. C.R. Acad. Sci. Paris, 249: 303-305

The soil was a rendzina with a calcareous substratum, its pH was 5, humus made up 0.4 %, C made up 4.5% and N 0.3%. The soil microflora was rather sparse; bacteria, actinomycetes and fungi predominated and algae were absent. N fixation (by Clostridium), cellulose decomposition (by fungi), proteolysis, ammonification and denitrification occurred; activity was largely catabolic. Bacteria and actinomycetes were greatly stimulated around roots but fungi were not.
