Nebraska precipitation map based on single point data

Why Do Precipitation Maps for the Same Date and Area Differ? June 28, 2018

Why do precipitation maps for the same storms sometimes appear to report different rainfall amounts? How can you determine which one to use when?

Flooding and Ponding in Corn June 22, 2018

Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.

Figure 1. The degree of damage from standing water in this field will depend on several factors and likely will lead to direct yield losses or indirect losses from increased disease pressure.

Flooding and Ponding in Soybeans June 22, 2018

Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.

Cover Crop and CO2 Emissions February 26, 2018

Do cover crops affect CO2 emissions from the soil and if so, under what conditions? These were among the questions addressed by university researchers monitoring CO2 emissions from cereal rye cover crops in irrigated and dryland no-till continuous corn treatments.

Taking CO2 measurements in plots where residue has been baled

Corn Residue Removal and CO2 Emissions February 26, 2018

University research looking at CO2 emissions from two types of residue removal (baling and grazing) compared with a control treatment found little day-to-day impact; however, when looking at cumulative data for the whole year, grazing did appear to affect cumulative CO2 emissions in irrigated crop-livestock systems. This data represents the first year of this study.

Eastern Nebraska wheat field that yielded more than 110 bu/ac. — Figure 1. High yields (more than 100 bushels per acre) were harvested in some eastern Nebraska winter wheat fields this year.

Recap of 2017 Eastern Nebraska Winter Wheat Crop August 31, 2017

While final USDA yield numbers aren't in yet, it looks like 2017 wheat yields could rival the 2016 yields in portions of eastern Nebraska, based on state variety trials and extension educator reports. See the breakdowns by district.

Wheat Planting Practices for Eastern Nebraska August 31, 2017

While many growers are thinking of fall harvest, others are preparing to plant their next wheat crop. Based on information from farmers, agronomists, and researchers, outlined here are seven key steps to help ensure a successful wheat crop.

Why Grow Winter Wheat in Eastern Nebraska? August 31, 2017

The winter wheat varieties planted in eastern Nebraska today can yield upward of 140 bu/ac under good management and weather. If you haven't planted wheat in several years, consider today's advanced genetics and these other benefits from integrating wheat into your rotation.
