The author, Gary Zoubek, stands in a field of corn being monitored for crop water use.. Corn is now at  the silking/tasseling stage in eastern Nebraska and irrigation has started..

This is the eighth in a series of weekly podcasts by Exension Educator Gary Zoubek on the use of ETgages and water sensors to improve irrigation management.  Following is an abbreviated summary from the podcast.

Hot humid conditions continued last week and are predicted to continue this week. The ETgages we’re monitoring in the Mead and York areas dropped 1.5 inches for the week. This is up slightly from last week, but is lower than expected given recent temperatures.

High temperatures for the week varied from 88°F to nearly 98°F and averaged 88°F, while the humidity was slightly down from last week, ranging from 62% to 84% and averaging 75%. The early planted and later planted corn that we’re monitoring is in the silking/tasseling stage with some silks starting to turn brown.

Soil Watermark readings in the fields being monitored varied from field to field, depending on rainfall received and whether the fields have been irrigated. Three of the four fields being monitored have been irrigated this season; the fourth has received timely rains and the pivot has not moved. Rainfall last week varied from 0.53 inches at the ARDC near Mead to 0.75 and 1.50 inches at two locations near York.
