Raking downed corn
Raking into windrows and using a combine pick-up attachment can be a good option for picking up downed corn. A photo series by Bob Klein in this week's CropWatch illustrates this and other grower experiences to harvest the most crop.

Grower Experiences with Picking Up Downed Corn

This photo series of grower solutions illustrates several non-livestock options for picking up corn on the ground, including the use of a rake and combine with a pick-up attachment.

Nebraska Corn Board Supports Free Corn Nematode Testing

A new program to provide free soil analysis for corn nematodes is being made possible by the Nebraska Corn Board. Growers are invited to submit soil samples to a University of Nebraska-Lincoln lab from now through spring to be tested for the root-lesion nematode.

Soybean Production

Nebraska Soybean N Trials

Pictured is the zero N control on the left and the 400 lbs/ac split N application on the right. Averaged over four sites the control yielded 73.4 bu/ac and the 400 lbs N averaged 78.9 bu/ac. (To view the results from this study, see https://go.unl.edu/smfdresults2013, pages 1-6.)

Nitrogen on Soybeans — the Hope Never Dies

Nebraska Soil Scientist Charles Shapiro offers a synopsis of two new publications, both with University of Nebraska authors, that address the question of the nitrogen deficit between soil supply and nitrogen fixation and what affects whether increased nitrogen leads to increased yield.
Soil Sample

Quality SCN Samples are Part Science, Part Art

Taking quality soil samples to test for SCN is part science and part art. The science is in how the samples are taken, while the art is in where they're taken to capture the best snapshot of SCN conditions. You'll want to consider these recommendations for getting the most from your SCN sampling this fall.

Weed Management

Low Temperature and Frost May Affect Efficacy of Burndown Herbicides

In many areas fall herbicide applications were delayed due to the late harvest. Applications can still be effective, depending on weeds present, temperature, rate of herbicide and additives used. The article offers recommendations for these late-fall applications and their importance, particularly for control of herbicide-resistant marestail.

University & Sprayer Co. Experts to Address Dicamba and Enlist Application

Learn how to achieve maximum performance while avoiding injury to conventional and non-Xtend soybeans at a Nov. 15 Sprayer Clinic. The clinic, which will be held at the University of Nebraska College of Technical Agriculture in Curtis, will focus on application of the new dicamba and Enlist herbicides.

Grain Management

Why Grain Test Weights Matter

What factors influence grain test weights and why aren't test weights necessarily an indicator of grain quality? More on these issues and what to consider when trucking high test-weight grain down the highway. When grain prices are lower and test weights are higher, it makes sense to check truck load weights prior to highway travel.

Crop Reports & Market Journal

Nebraska Soybean Production up 4% from '16, Corn Down 2%

Based on November 1 conditions, Nebraska's 2017 corn crop is forecast at 1.66 billion bushels, down 2% from last year's production. The soybean crop is now forecast at a record 328 million bushels, up 4% from last year.

Corn Harvest at 68%; Soybean at 95%

As of Nov. 6 USDA NASS estimated Nebraska corn harvest was 68% complete, behind 82% last year and 81% for the five-year average. Soybeans harvested was 95%, equal to last year, and near the five-year average of 98%.
