Emergence of Corn in Relation to Soil Oxygen Diffusion Rates1

R. W. Wengel2

Percent emergence of corn from soil was related to soil oxygen diffusion rates in an exponential manner. A "critical" diffusion rate range of 20–25 x 10–8 g O2 cm–2 min–1 was indicated. Oxygen concentrations in the soil atmosphere may have been a factor affecting emergence independent of the oxygen supply based on plantinum electrode measurements.
