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 ✕ 10 −8 g O 2 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.
