In 1943 Lochhead and Chase (97) devised a system of nutritional classification of soil microorganism which has since proved to be of considerable value as a method of characterizing the soil microflora and hence of studying changes in the distribution of the nutritional groups of organisms comprising the flora, under different soil conditions. The procedure used by these workers, which was based upon the growth response of individual soil isolates in six nutritional media, proved to be cumbersome in the laboratory, largely because of the necessity of using one hundred or more isolates from each soil sample to obtain statistically valid results.
