13	Urea metabolism in a black spruce humus. Roberge, Marcien R. January 1965 (has links) Knowledge of the relationships between nitrogen fertilization and nitrogen availability is needed to guide plans for providing optimum tree growth by silvicultural operations. PART 1. Detailed studies of the mineralization of urea were made by laboratory incubation of black spruce humus samples. These studies form a part of an experiment in which urea is used for the first time to fertilize a soil supporting a black spruce stand. Urea seems to be a very good fertilizer because it is readily transformed to an available form of nitrogen. It is however doubtful that a nitrogen fertilization only could quickly and greatly affect the humus fertility. PART 2. Total number and number of ureolytic bacteria and fungi were determined at time intervals during a laboratory incubation of black sprucc humus samples. Such a quantitative and qualitative study of the microbial population of a raw humus had never been made. The potential for ureolysis is enormous because this humus contains an abundance of ureolyzing microorganisms Indeed, counts in excess of 100 millions per gram are not uncommon.
