The microflora in the soil and in the run-off from the soil

1940

Wilson, J.K. | Schubert, H.J.

The quality and the quantity of the microflora in the soil of the plats and in the run-off from these soils were determined. The counts of the organisms of the various physiological groups were expressed as numbers in each gram of solids. By averaging the data, all determinations show that the total number in the run-off exceeded that in the original soil about 200 times. The number of ammonia and sulfur oxidizers, of Rhizobium trifolii, and of anaerobes that were found in the soil or in the run-off from the soil constituted a small fraction of the total population. Under the conditions of these tests fertilizers did not affect the number of organisms in the sample of the original soil or in the run-off obtained from the soil.
