The worst compaction happens on the first pass across the field, so controlling traffic will help minimize compaction as a whole. Insights on how wet field conditions affect compaction and ways to mitigate compaction when field work can't be delayed.

A new herbicide, KHNP0090, has been developed by Bayer CropScience for application on dicamba-tolerant soybeans and cotton. The public has until June 3, 2024 to make comments on the registration of a new Bayer CropScience dicamba product for dicamba-tolerant soybeans and cotton.

The public is invited to hear insights from numerous innovative companies on revolutionary new and emerging technologies for the ag industry at the next Heuermann Lecture, which is free to attend and will be livestreamed.

For more information or assistance with completing a USDA NASS survey, visit the respondent portal. Producers are encouraged to provide information on planted and harvested acreage, including acreage for biotech crops, and grain stocks, to aid NASS in determining the national supply of commodities for the 2024 crop year.

Though delaying small grain harvest can produce higher yields, it also decreases crude protein content. Producers should consider the animal being fed and feeding method before harvesting to get the most out of these crops. With the first harvest of 2024 beginning soon, producers should take this time to perform equipment maintenance and strategize the timing of alfalfa and small grains harvest based on operational needs.

Historical crop production reports for Nebraska are available at USDA. Nebraska's hay stocks are currently up 79% from last year.

Historical crop progress data for Nebraska is available at USDA. With drier weather last week, Nebraska farmers began to close the gap on planting delays, but corn and soybean remain 15-18% behind last year's progress for this time of year.

A glance at this week's crop water estimates and tips for Nebraska producers as they prepare for the 2024 irrigation season.

Crimping rye at a mild angle using a roller crimper. (CropWatch file photo) This short program will include a roller crimper demo, discussion on what conditions must be met to be successful with this termination method, and insights from farmers on their experiences with crimping.

The National Center for Resilient and Regenerative Precision Agriculture at Nebraska Innovation Campus will be a $160 million USDA laboratory, enabling USDA ARS to perform research on wheat, barley, sorghum, forage and bioenergy grasses, and other crops. Research on how these plants respond to emerging pests and pathogens under a full range of environmental conditions will empower scientists to make cutting-edge discoveries with the goal of developing climate-resilient crops for the U.S. agriculture industry. (Nebraska Today image) The state-of-the-art research center will enhance USDA ARS studies on the impact of emerging pests and pathogens on crops with the goal of developing climate-resilient crops for the U.S. agriculture industry.

This webinar reviews the pros and cons of adding an annual forage into crop rotations, with insights from Mary Drewnoski, extension beef systems specialist, Jay Parsons, extension farm and ranch management specialist, and Daren Redfearn, extension crop residue specialist. (USDA NRCS photo) This webinar highlights the economics and production benefits of incorporating annual forage systems into crop rotations for producers interested in diversifying their operation.

Figure 1. Probability of one inch of precipitation early next week. There is more rain expected for Nebraska next week, but it's likely to be followed by an extended dry period.

Figure 1. A grower’s wheat field in Lancaster County in southeast Nebraska with low levels of disease on May 8. (Photos by Stephen Wegulo) The appearance of wheat disease has increased in Nebraska, with new observations of stripe rust in several counties and low levels of barley yellow dwarf and leaf spot diseases.

For pastures with noxious weed thistles like this musk thistle, now is the time for spring herbicide applications, while the plants are still in the short rosette to bolted growth stages prior to flowering.

Three Nebraska Extension NebGuides have been updated to include information about the new UNL Nitrogen Tool, designed to increase efficiency of nitrogen use in crop production. The updated publications provide information about UNL's newly developed web-based nitrogen (N) recommendation tool for corn grain, adapted from extension's previous N recommendation equation.

Gary Peterson, Colorado State University professor emeritus, delivered the opening keynote presentation at the Nebraska Soil Health School held at UNL’s High Plains Ag Lab on April 24. Peterson outlined historical events and mismanagement practices that have degraded the Great Plains soil and discussed the how and why the coupling of reduced tillage and cropping intensification can help growers rebuild soil. (Photo by Nicole Heldt) The first Nebraska Soil Health School of the year was designed to provide potential management practices for producers in the Panhandle, with one focus being the practicalities of growing cover crops in semi-arid regions.

For concerns regarding the use of chlorpyrifos on crops during the 2024 growing season, producers should contact their local extension educator for assistance. Nebraska Extension educators share guidance on the use of chlorpyrifos products on food and feed crops in the U.S.

Attendees of Land Management Quarterly can submit questions to the presenters prior to the webinar using the questionnaire form on the Land Management Quarterly website (link in article). The May 20 webinar will examine the latest average cash rental rates in the state and offer insight on adjusting rental rates considering current commodity prices this year, including a Q&A session for participants.

Historical crop progress data for Nebraska is available at USDA. Nebraska's recent turbulent weather caused some setbacks for corn and soybean planting, with corn planting now almost 20% behind last year's pace.
