Fall is Optimal for Marestail Management October 28, 2016

With corn and soybean harvest nearing completion in Nebraska this is a great time to begin scouting fields for winter annual weeds like marestail. Timing is critical to successful control of marestail, especially in no-till soybeans as many populations have evolved resistance to glyphosate and ALS-inhibiting herbicides.

Nebraska 2016 Wheat – High Yields, Low Protein September 1, 2016

Environmental conditions, management, and genetic differences played a role in why protein content in the 2016 wheat crop was lower than normal. Wheat protein develops as the plant converts nitrogen from the soil into amino acids. See what conditions led to low protein this season and how to address it for next year's crop.

The Value of Wheat in a Crop Rotation August 31, 2016

Wheat is an important part of many crop rotations, adding value directly and often indirectly by aiding in soil water management and weed suppression, reducing erosion, and helping manage pest cycles. Consider wheat's value to your crop production system by looking at what it contributes over multiple years of the rotation.

Fall Weed Control Options for Winter Wheat August 31, 2016

Weed management is a long-term battle that needs to continue even in tight margin years.Although herbicide costs may seem prohibitive, it’s important to consider the long-term implications of limiting or eliminating the use of herbicides in crop production systems.Weeds left unmanaged after wheat harvest use valuable nutrients and water needed for the following year’s crop while producing seeds to replenish the soil seed bank.

Sprinkler Irrigation System Maintenance for Improved Uniformity and Application Efficiency August 23, 2016

Center pivot irrigation systems are designed and managed to apply water as uniformly as possible to enhance crop production. Uniformity has a direct effect on the system’s overall application efficiency, which is a measure of how well an irrigation system delivers water to a crop’s root zone.
