A Snapshot of Soil Fertility Levels Heading into Spring
March 30, 2007

 The following maps and graphics illustrate average soil nutrition and fertility levels from soil samples analyzed by Agvise Laboratories last fall.  With laboratories in Northwood, N.D. and Benson, Minn., Agvise (www.agvise.com) provides soil testing and plant analysis for crop consultants, fertilizer retailers and producers.

John Lee, soil scientist with Agvise in Northwood, cautions that these numbers are just big picture snapshots to help gauge soil fertility trends.  As averages, you can expect half of fields to be more, and half of the fields less, he says.  While it is interesting to look at the big picture to see the overall trends, the only way to know for sure what nutrients your fields need (or dont need) is through soil sampling analysis.
