Long-Term Study Suggests Management Adaptations for Weather Extremes

July 16, 2019
From droughts to flooding, extreme hydrological phenomena are the costliest hazards in rainfed agriculture. A recent journal article explores how a long-term tillage study in northeast Nebraska can offer insights on successfully adapting to future climate changes by adjusting specific management practices.

Research Update: Control of Perennial Invasive Weeds Requires Repeated Herbicide Applications

June 4, 2018
Research shows the need for patience and persistence when battling perennial weeds such as purple loosestrife over multiple years. The younger the stand the faster the control was achieved.

Study: Efficacy of Herbicides in Buckbrush Control

May 22, 2018
A two-year weed management study in northeast Nebraska evaluated herbicide options for controlling buckbrush, a common perennial weed in Nebraska pastures and rangeland. One herbicide provided year-round control, while several others provided season-long control.

Research Findings on Chemical Control of Cottonwood

May 22, 2018
Cottonwood offers many benefits, but also can be an invasive and difficult-to-control weed. Nebraska researchers studied control efficacy of eight herbicides over two years and found three products provided total control more than a year; however, they also noted a caution for areas with high water tables.

Preemergence Herbicides Delayed the Critical Time for Weed Removal in Soybean

May 16, 2018
Researchers tested two herbicide strategies in soybean to see how preemergence herbicides would delay the critical time of weed removal, likely reducing the number of herbicide applications needed in a season.
