Prior to storms July 8-9, plants were nearing tassel, a critical time for photosynthesis and pollination. These storms resulted in “flattened” corn from lodging/leaning in addition to bent and snapped plants. "Recovery" depends on a variety of factors.
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.
