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.

Irrigation Sensor Installation Tips

May 26, 2016

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.

1)  When should sensors be installed?

Atmometer (ETgage) Installation Tips

May 26, 2016
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.

Q and A: Should I Keep My Initial Corn Stand or Replant?

May 13, 2016
When deciding whether to replant a less than optimum corn stand, consider current stand, potential yield, and potential yield of replanted crop at this point in the season. The authors guide you through the process of assessing the stand, and next steps, if necessary.
