115 Years of Data Reveal Longer Growing Season, Changing Temperature Trends June 29, 2018

The past century of climate change has extended the average U.S. growing season by nearly two weeks but driven annual buildups of yield-stifling heat in the West and Northeast, says new research from the University of Nebraska–Lincoln.

Nebraska Entering a Dry Phase for Next 6-7 Years December 5, 2017

A closer look at wet and dry periods for the last 120 years in Nebraska indicates the state is entering a dry phase expected to continue for the next six to seven years. While there may be wetter "exception" years during this period, the general trend is for drier than normal precipitation during this period.

Risk of Freeze Damage in Early-Planted, Emerged Corn April 28, 2017

Early-season freeze damage results in a range of potential yield impacts. Severe damage is often limited to low-lying areas within a field because cool air is heavier than warm air. Early season survival of corn plants is attributed to growing-point protection below the soil surface; however, a hard frost can penetrate the ground and kill plants. Regrowth of corn following freeze damage is often impeded by dead leaf tissue that can entrap new leaves.
