Nebraska Extension is hosting two After the Storm programs Monday, Aug. 13, to look at expectations for progress of hailed crops and management options going forward, including grain storage, cover crops, silage, and forage.
Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.
Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
This week several corn fields in south central Nebraska were surveyed to assess damage and longer term effects on stands after last week's high winds and resulting dust storms. While many plants were seriously injured, many would be expected to recover.
In Thursday night's thunderstorm in western Nebraska center pivots were flipped over, power poles were snapped off, and trees were uprooted with gusts of 60 mph. See Nebraska Extension Educator Gary Stone's photo report.
Spotty rains and drought conditions in some areas of the state as well as hail and wind damage are leading growers to seek alternative uses for rainfed corn fields. Fortunately, there are several forage alternatives.
Additional time is needed to properly access the injury and potential yield loss of Nebraska winter wheat, given the cold temperatures that followed last week's below freezing temperatures, heavy wet snow, and high winds. It takes at least a week to 10 days of warm temperatures to make a quality assessment.
Similar to last year’s heavy rains in early May, rain on May 9 and May 10-11 in portions of Nebraska have caused ponding and flooding across some fields. As of Sunday, May 8, USDA-NASS reported that 57% of Nebraska's corn was planted that is behind the 71% planting progress in 2015 but close to the
