A Summary of Western Ag's Fall 2009 Field Soil Testing Results.

Hammermeister, E.H., A. McDonnell and S. Hancock. 2008. Soils and Crops


The reporting of regional or provincial soil test summaries has varying degrees of value depending on the individual using the data. The monitoring of yearly data will give indications of "average" soil nutrient supply changes over time. As well, year to year differences can provide the fertilizer industry signals of anticipated demand. The relevance to an individual field is quite limited. The data presented here is a summary of fall 2009, and a three year comparison of N, P, K, and S soil supply rates as measured by PRS™ (Plant Root Simulator™) Probe Technology at Western Ag Labs Ltd.
