Soil testing is the only way to accurately identify and monitor soybean cyst nematode, which may be the cause of unidentifiable yield loss during fall harvest.
Using a Cornstalk Nitrate Test to Evaluate Nitrogen Management Decisions
September 29, 2022
At the end of the season, a nitrate test can help determine whether the crop was under-, adequately or over-fertilized with nitrogen, resulting in the potential to significantly reduce input costs.
Cropland Reference Ecological Unit — A Land Classification Unit for Comparative Soil Studies
September 29, 2022
UNL researchers have developed the Cropland Reference Ecological Unit and Soil Health Gap concept to offer a method of describing the true soil health potential of land.
Assessing Soil Health at the Field Scale: Putting Reference Soils and Sampling Strategies All Together
September 28, 2022
In a recently published article, UNL researchers help shed light on common questions related to using cover crops as a way to meet soil health goals.
Another Dry Year: What to Know About Leftover Nitrogen in Soil Following Dry Conditions
September 28, 2022
In irrigated or dryland areas with normal production, management practices may continue as normal, but for dryland areas with drastic yield reductions, there is potential for nitrogen fertilizer adjustment for the 2023 crop.
Free Farm Succession Workshops in December
September 27, 2022
The Nebraska Rural Response Hotline is hosting three workshops in December that will help producers build business succession plans and better understand certain tax measures, such as inheritance tax and federal transfer tax.
Crop Progress: Harvest Continues Near Average Pace, Slow Start for Winter Wheat Emergence
September 27, 2022
Harvest is progressing at average pace for all crops except dry edible beans, which continue to lag last year's harvest pace by 16%. Winter wheat emergence is also behind at 4% as of Sept. 25, compared to the average 15% for this time of year.
Pasture and Forage Minute: Grazing for Interseeding, Controlling Thistles and Fall Armyworms
September 27, 2022
Following last year's atypical infestation of fall armyworm caterpillars, extension educators urge preparedness in the event of a reoccurrence this fall. Plus — why overgrazing is a good strategy prior to interseeding legumes.
