Corn growing in flooded soil

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.

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.

Is Soybean Yield Limited by Nitrogen Supply?

January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics exploring research on whether nitrogen supply is limiting soybean yield.

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.

Corn Disease Update: Southern Rust Increasing; Diplodia New to Nebraska

July 27, 2017
Warm, wet conditions across Nebraska the past two weeks created optimal conditions for crop diseases. This update looks at identification and management of three diseases in corn: southern rust, which is expanding in the state, bacterial leaf streak, and diplodia, which is new to Nebraska.

Help Us Identify Yield-Limiting Factors in Nebraska Soybean Fields

October 5, 2016
Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.
