Wondering how best to manage the flush of winter annuals that came up during the recent warm spell? Are they likely to survive a return to winter conditions? This Q&A addresses these and related questions on pre-season weed management.
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.
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.
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.
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.
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.
