Pellets prepared from spongy, unhumified peat, were found to be well suited to the growth of the test organisms and were superior to pellets made from compressed, well humified peat. Sterilization had the effect of lowering somewhat the absorptive ca

Comparative studies of the relative incidence of bacteria of different nutritional requirements in soil indicate that one of the most characteristic rhizosphere effects is the preferential stimulation of bacteria requiring amino acids for maximum gro

Comparative tests of various powdered materials showed that well humified peat was superior to other preparations in maintaining the test bacteria in viable condition. Under the test conditions, sterilization of peat improved it as a medium for the m

Numbers of Rhizobium trifolii, Rh. leguminosarum, Rh. meliloti and Azotobacter were determined at four-week intervals throughout a four-year crop rotation in three soils which had been receiving for twenty years no fertilizer, manure, and artificial

STUDIES of the nutritional requirements of soil bacteria isolated on a non-selective basis1 have shown the presence of a well-defined group of organisms dependent upon soil extract for maximum growth. These bacteria show no growth, or at best sub-max

EARLIER studies in this laboratory1 have indicated the presence in soil of bacteria dependent upon growth-factors provided by soil extract but not by yeast extract nor by combinations of amino-acids and vitamins (not including B12). More recently it
