 This ETgage is placed at least a foot above the crop canopy to record estimated ET loss over a given period. This early planted corn is just entering the tasseling stage. (Photos by Gary Zoubek) |

 A field near York at the silking stage. The Nebraska Agricultural Statistics Service estimated on July 17 that 34% of the crop had silked. |
This is the seventh 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 through last week and are predicted for this week. The ETgages we’re monitoring in the Mead and York areas dropped an average of 1.35 inches for the week. This is the same as last week.
High temperatures for the week varied from 77° F to nearly 97° F and averaged 88° F. Humidities were similar to last week, ranging from 73% to 84% and averaging more than 81%.
The early planted corn is in the tasseling stage with lots of green silks and pollen starting to be shed. Readings from the Soil Watermark sensors in the York fields varied. In two fields the sensors were reading near 70 in the top foot and in the 50s at the two- and three-foot levels with depletions of about 1 inch to a little over 1.55 inches. The third field had a depletion of about one half inch. The field at the ARDC is on a fine sandy loam. It was irrigated last week and has a current depletion of 0.4 inch.
