Some fields across South Arkansas have had irrigation terminated for a few weeks and are very close to harvest with a little bit of harvest beginning this week. The Prairie County Verification Field reached black layer on Tuesday (7-30). The final irrigation for Jefferson County field was started on Tuesday. Three other fields need anywhere from 1.5 to 0.75 inches of water to finish out to black layer. We are still getting irrigation termination questions, so I have included the following two resources again this week: Dr. Jason Kelley, Extension Agronomist – Wheat and Feed Grains, wrote a newsletter that addresses irrigation termination for Arkansas Row Crops, which can be found at www.arkansascrops.com with direct link http://www.arkansas-crops.com/2019/07/22/corn-irrigation-terminated/. Dr. Chris Henry, University of Arkansas Irrigation Specialist, has put together a fact sheet to help predict final irrigation using soil moisture sensors, which can be found at https://www.uaex.edu/environment-nature/water/Irrigation%20Termination%20Factsheet%20July%202018.pdf.
I have not found any more Southern rust this week. It has not spread in the White County field or Desha County field.
