A2809 Update Coming Soon

A2809 Update Coming Soon

Carrie Laboski, Extension Soil Fertility and Nutrient Management Specialist

University of Wisconsin-Extension publication Nutrient Application Guidelines for Field, Vegetable, and Fruit Crops in Wisconsin (A2809) has been revised. There are numerous changes to this edition that are designed to simplify and customize the nutrient recommendation process. A few specific changes include: 1) a reassessment of soil yield potential and a transparent description of how they are defined based on soil properties; 2) a refinement of our P and K recommendation philosophy; 3) updated N rate guidelines for corn; 4) wheat N rate guidelines using a MRTN approach; and 5) updated manure nutrient availabilities.

To learn more about the changes to A2809, attend one of the Soil, Water, and Nutrient Management Meetings that run from November 27 through December 6. Two hours of the meeting will focus on A2809. For more details about the meetings see: http://www.soils.wisc.edu/extension/cal/2012area.pdf

The updated edition of A2809 will be available as a PDF (free) or paper ($7) bulletin at http://learningstore.uwex.edu on November 19.
