Quality SCN Samples are Part Science, Part Art November 9, 2017

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.

The combine was considered a total loss, but the quick response of firefighters allowed them to save the bean head, and control the fire from spreading into surrounding vegetation.

Keeping Your Equipment and Fields Fire Safe At Harvest October 18, 2017

When residue builds up in your combine or poorly maintained equipment creates sparks, fires can ignite, quickly enveloping your equipment and field. Incorporating the practices outlined here into your harvest routine can help you stay safe this fall.

Improving Soybean Profitability: SCN March 3, 2017

The easiest and least expensive way to improve profitability for many soybean growers in tight economic times, or any time, is to sample fields for soybean cyst nematodes (SCN). In Nebraska trials growers realized an average six-bushel-per-acre soybean yield increase after taking no-cost steps to manage SCN.

SCN Now Confirmed in 58 Counties; How About Your Field? February 16, 2017

Soybean cyst nematode is estimated to cause $40 million in lost soybean yields annually in Nebraska. Soil tests, available free through a program funded by the Nebraska Soybean Board, can help growers identify where this nemesis is a problem so they can manage that field accordingly.

Test for SCN This Fall & Select Seed Accordingly October 31, 2016

If you noticed some areas of your soybean fields that didn't yield as well as expected, this fall would be a good time to soil test for soybean cyst nematode. In University of Nebraska research of SCN-infested fields, switching to an SCN-resistant variety increased yields as much as 6 bu/ac.

Help Us Identify Yield-Limiting Factors in Nebraska Soybean Fields October 5, 2016

Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.

Soybean Aphids Found in Northeast Nebraska; Scouting Warranted July 28, 2016

This week soybean aphids were found in several northeast Nebraska fields at low numbers. Although it has been too hot for soybean aphids to thrive, populations could quickly increase with cooler temperatures. Scouting is recommended at this time.
