Understanding how the three types of nitrogen stabilizers work can be helpful in deciding whether to add one to your spring application. Short- and long-term studies in Nebraska offer insight into how they performed across multiple years. Now, if you only knew how many inches of rain you'd get the first six weeks after application.

University of Nebraska research is offering new insights into plant use efficiency of organic N resources such as livestock manure, municipal bio-solids, and others. The studies continue through 2018 and are expected to influence changes in university recommendations.
Micronutrients are in the spotlight these days with new biological products coming to market. This update looks at micronutrient research updates, including which nutrients are likely to enhance profit and how results can differ among different soil tests.
When is applying sulfur likely to be profitable and when is it cutting into your potential profit? This brief shares information from more than 100 university trials verifying current university recommendations.
The NebGuide, Nutrient Management in Organic Farming, features information also of value to conventional production, including manure management, composting, non-traditional products, and crop rotation suggestions.
Are you considering using a new soil nutrient product this season? Learn what farmers learned from these nine studies of alternative nutrient supply products and practices, conducted as part of the Nebraska On-farm Research Network (NOFRN) in 2017.
Three studies with a total of 50 trials applying K at various rates to corn verified that the likelihood of a profitable response is very low if the soil test level is above 125 ppm.
