You Can Postpone Phosphorus, Potassium, and Zinc Fertilizer Applications When…. February 28, 2017

Soil testing and applying only the soil nutrients needed to produce your yield goal can provide a significant savings in fertilizer costs. Nebraska research shows growers can save as much as $52.12/acre for postponing phosphorus, potassium and zinc applications.

Finding Win-Win Opportunities for Manure February 27, 2017

Land application of manure can create a win-win scenario for your farm by providing valuable crop nutrients while helping build soil organic matter. Learn more about the benefits of replacing commercial fertilizer with manure and how to get the most value when integrating an application into your soil nutrient plan.

Cutting Costs Without Hurting Yields? Check Fertilizer N Rates in Corn after Alfalfa February 22, 2017

With tight crop margins for the 2017 growing season, many farmers are looking for ways to cut input costs without hurting yields. One way to do this is by giving the appropriate nitrogen credit when calculating how much N to apply to corn grown after a prior alfalfa crop.

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.

Is Nitrogen Fixation Oversold with Legume Cover Crops? December 16, 2016

One expected benefit of using legumes as a cover crop is to provide a source of nitrogen (N) to the cropping system. However, when legumes are included in mixtures with grasses and broadleaves for a relatively short growing period, the amount of actual fixed N may be relatively low.

Project SENSE Sessions to Feature High-Tech Sensors in Action July 20, 2016

Project SENSE update sessions are planned for several locations across Nebraska. Growers will learn how to outfit and implement the project's nitrogen management strategy on their operations. Project SENSE (Sensors for Efficient Nitrogen Use and Stewardship of the Environment) focuses on improving the efficiency of nitrogen fertilizer use.

Q&As: How much N is Left? Do I Need More Starter When Replanting? May 27, 2016

Well, it seems not much has changed since the last article I wrote on nitrogen (N) management a few weeks back: more rain, more to come, and more uncertainty with regard to N. So, what do we do now and why I am not worried about the other nutrients? Why is it always about N?
