A new nutrient management website has been launched that houses most of the current fertilizer suggestions and data from the University of Minnesota. This website was made possible by funding from the Minnesota Agricultural Fertilizer Research and Education Council and was put together through a joint effort for several researchers from the University of Minnesota who's research focuses on nutrient management issues for several crops growth throughout the state of Minnesota. We would like to thank the AFREC program because without them this effort would not have been possible
This website was established in order to house much of the current publication, research reports, and selected extension presentations. In addition research reports on 50 years of soil fertility research are included from the series of Blue Books published over many years. Several publications were updated upon the release of this website while others are in the process of being updated and will be gradually added over time.
The Updated publications include
Lime needs for Minnesota
Liming materials for Minnesota
Fertilizing Alfalfa in Minnesota
The major update for the Alfalfa publication involves new sulfur suggestions for alfalfa grown on fine textures soils.
In addition a new publication on Managing iron deficiency chlorosis was added and is based on current research.
In development are updates on the wheat, barley, and soybean guidelines and the development of a new publication on plant tissue analysis.
In addition, we have started to develop web based calculators for making nutrient management decisions based on soil test data. At this time only the guidelines for wheat and soybeans have been used to develop calculators for those specific crops. Additional crops will be added over time to have a complete set for guidelines in the state of Minnesota.
This is the first stage in the development of the nutrient management website. We will over time add new features. In addition to the website we have opened up a Facebook page for the MN nutrient management group. This is meant to be a forum where issues can be brought up and discussed and we can highlight current finding or observations from the field on a daily basis.
This page can be found at
Or by clicking on this link: Nutrient Management Facebook Page
Over time we will start to update this page with photos and video clips that highlight some of the things we are seeing in the field but we also welcome people to submit nutrient management related issues in oder to make the site interactive to discuss issues that are happening out in the field.
