The corn at the Agronology 10 Research Center planted on 24 April 2012, began spiking through the soil on Friday, 4 May. So far in May, the research plots have received 5.1 inches of rain. In one of the wetter areas, the corn has not spiked through the soil yet. This delayed emergence is most likely caused by a lack of oxygen (too much water). We may have to replant this wet area.
