Corn Growth as Affected by Aggregate Stability, Soil Tempearture, and Soil Moisture

1964

Anderson, W. B. | Kemper, W. D.

SynopsisThe highest yield was obtained on the 5370 water-stable aggregate treatment , indicating that natural aggregate stability levels may have been higher than those required for optimum yield of corn tops. Corn roots growing in conjunction with the soil microorganisms depleted the oxygen supply of the soil air to somewhat lower values than did the organisms alone. Rate of oxygen use per cc. of roots was greatest at higher oxygen levels and fell off sharply with decrease in oxygen content of soil air.
