Soil Management

The Long View of Nitrogen Recommendations from Nebraska Extension January 6, 2017

At the 2017 Crop Production Clinics, the Nebraska Extension Soils Team is presenting a historical overview of how nitrogen recommendations for corn have developed and changed since the 1950s. We are also discussing what may lay ahead for nitrogen management.

Student Research: Does the Grazing of Cover Crops by Cattle Compact Soil? November 2, 2016

Undergraduate Rebecca Clay shares the results of her study on whether grazing cover crops contributed to soil compaction at four sites in west central and eastern Nebraska. Clay, an undergraduate student in the Iowa State University Department of Agronomy, conducted the study as part of a UNL Research and Extension Experiential Learning Fellowship in summer 2016.

Nebraska 2016 Wheat – High Yields, Low Protein September 1, 2016

Environmental conditions, management, and genetic differences played a role in why protein content in the 2016 wheat crop was lower than normal. Wheat protein develops as the plant converts nitrogen from the soil into amino acids. See what conditions led to low protein this season and how to address it for next year's crop.

Managing N in a Wet Spring May 5, 2016

USDA NASS estimated 26% of Nebraska’s corn acres had been planted as of May 2, well behind last year’s pace of 45% and slightly behind the five-year average of 31%. The pace is undoubtedly being affected by the amount of precipitation across the state and the wet field conditions (Figures 1 and 2).

Project SENSE sensors in the field.
Figure 1. UNL researchers are testing the use of crop sensors and real-time N application in the field based on sensor readings. The project was started with 17 sites across the state in 2015 and will be expanded to 20 more sites in 2016.

UNL Project SENSE Expanding Research to Increase N Efficiency May 5, 2016

When and at what rate nitrogen fertilizer should be applied are major questions for today's corn producers. Nebraska Extension is helping answer these questions through Project SENSE, which stands for Sensors for Efficient Nitrogen Use and Stewardship of the Environment.

Managing and Preparing for Nitrogen Loss March 24, 2016

Spring is officially here, and with it the uncertainty of spring rains or late snow showers. For many Nebraska farmers, finishing preparation for planting or waiting on the starting line to plant is the number one priority. Nitrogen (N) management may not be the most important thought crossing their minds. But, now is a great time to think about N management for this upcoming season.
