Information and Resources for Flooded Fields June 28, 2018

Following heavy rains in northeast Nebraska this week, many growers are facing some tough decisions. This offers information and resources to aid in assessment and decision-making.

Figure 1. The degree of damage from standing water in this field will depend on several factors and likely will lead to direct yield losses or indirect losses from increased disease pressure.

Flooding and Ponding in Soybeans June 22, 2018

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.

Flooding and Ponding in Corn June 22, 2018

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.

End of Season Flooding Effects on Soybeans, Harvest October 13, 2017

October has gotten off to a wet start in most of the state and particularly in northeast Nebraska where some mature soybean fields are now flooded. Considering potential impact on yield and ability to harvest these fields will be critical in the next few weeks.

Effect of Excessive Rainfall on Efficacy of Residual Herbicides Applied in Corn and Soybean May 23, 2017

How excessive rainfall may affect the efficacy of residual herbicides is complex and influenced by multiple properties of the soil and the herbicide applied.

Corn Survival in Ponded or Flooded Fields May 19, 2017

Heavy rains of 2 to more than 4 inches in south central Nebraska May 15-19 have led to ponding or flooding in many fields. Survival of young corn plants under these conditions depends on several factors, described here.

How Saturated Soils Affect Germination, Seedling Growth May 12, 2016

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
