Both corn and soybean are susceptible to extreme heat (and water) stress during early vegetative stages as well as later critical growth stages (pollination for corn and flowering for soybean). Extreme heat stress can reduce plant photosynthetic and transpiration efficiencies and negatively impact plant root development, which collectively can negatively impact yield. The author recommends that during an extended heat wave (air temperature equal to or greater than 90 F for 7-10 days), applying 0.25-0.40 inch of water can be very beneficial.
Nebraska Extension's new Agricultural Water Management Guide, an online, interactive resource, offers information, videos, and illustrations about various types of irrigation, their advantages and disadvantages, technologies and strategies.
Minor to moderate lowland flooding is still occurring along the North Platte River from Lewellen west into southeastern Wyoming and will continue for several weeks or months. The areas affected are primarily the river bottom, pasture, and low-lying agricultural production fields. Some areas are near flood stage and others have exceeded flood stage.
As planting progresses across the state, it is recommended that irrigators start installing water sensors in fields as time allows. Any time sensors are installed, a few simple questions should be addressed to ensure accurate readings for irrigation management later this season.
ETgages estimate potential crop evapotransiration, allowing growers to track crop water use and apply irrigation more precisely when the crop can best use it. Learn about how to prepare and install ETgages and use the resulting data. Includes table of crop coefficients for corn, soybean, and wheat.
A collaboration of management agencies is closely monitoring the situation as reservoirs on the North Platte River in Wyoming fill and water is released. Flooding is likely in an area along the river in western Nebraska for several weeks to several months. Minor to moderate lowland flooding is occurring along the North Platte River from Lewellen west into southeastern Wyoming and will continue for several weeks or months. The areas affected are primarily the river bottom, mostly pasture but some cropland and homes.
The annual water and natural resources tour, hosted by the University of Nebraska's Nebraska Water Center and the Central Nebraska Public Power and Irrigation District, will be in Colorado this summer.
The US Bureau of Reclamation presented their North Platte River water update and forecast of water operations for the 2016 season at a recent meeting at the University of Nebraska Panhandle Research and Extension Center in Scottsbluff.
