South Arkansas: All fields are approaching midseason or beyond except for Pulaski County which went to flood this past week. The fields scheduled for midseason nitrogen are Arkansas, Clark, and Desha. The Lafayette County field has received its midseason nitrogen application. The Lonoke County field according to GreenSeeker does not need a midseason nitrogen application and will verify with next visit. Disease pressure continues to be low despite more favorable conditions. Lincoln and Prairie County are scheduled for late boot nitrogen applications next week.
North Arkansas: All fields continue to progress well. Only Randolph County has not reached internode elongation at this point but it too is growing rapidly and the field had its preflood nitrogen and permanent flood applied this week. GreenSeeker technology revealed that nitrogen levels in Conway and Woodruff Counties plus 10 acres in White County justify an unplanned midseason nitrogen application. Circumstances causing this problem varied in each field but regardless of how it occurred, a reliable technology to help detect and correct this situation early is a good management tool to have.
