Spring is always a good time to clean house and freshen up resources. This blog is the second in a series, providing updates to commonly used web-based resources and electronic communications. The first blog, Insect Management Resources, was published earlier this week.

The North Central Extension Research Activities-103 or NCERA-103 committee, made up of extension and research scientists in the upper Midwest serves to facilitate cooperative research and education in specialized soil amendments and products, growth stimulants and soil fertility programs. The committee maintains a web page that serves as a digital repository for research reports titled Compendium of Research Reports on Use of Non-Traditional Materials for Crop Production. The compendium maintains strict criteria for inclusion of reports that are listed on this site. Given the recent explosion of products categorized as biologicals, this site can provide information on research conducted by land-grant universities in the upper Midwest related to such products. It should be noted not all products have been researched and not all research reports are included in this compendium. The compendium has recently been moved to a new server so please update any previous bookmarks to reflect the current link above.

The Corn Nitrogen Rate Calculator (CNRC) has found a new home. The CNRC was developed in 2004 and is supported by university research from seven Midwest universities. The original goal of this site was to develop N rate guidelines on a regional basis and to provide data that allowed producers to make the most profitable N fertilizer rate decisions for corn production. The site itself has not changed, but it is housed on a new server. If you currently have the old site bookmarked, please update your link to
