The Iowa State University Extension and Outreach Soil Fertility web site has undergone a recent redesign and update. The site was updated, but the URL has remained the same ( While the site has been a resource for several years, it was in need of an overhaul. Part of the update was to improve flow and access to the different areas of the site. Other updates were needed to meet university requirements.

The original Nutrient Topics areas are still there, such as lime and soil pH, nitrogen, phosphorus, potassium, manure nutrients, secondary and micronutrients, soil/plant sampling and testing, and nutrients and water quality. In each nutrient topic section, information is available that is pertinent to that topic; including Extension and Outreach publications, newsletter articles, conference proceedings and reports, presentations, and links to related web sites. The Photo Gallery still contains a large number of nutrient related pictures. As before, the Current Topic articles are still located on the main page. New features include a Quick Links list and a featured web site or publication on each page.

We hope you will use the ISU Agronomy Extension Soil Fertility Web Site as your source of soil fertility information and your initial stop when accessing the Web.
