A Summary of Fall 2011 Saskatchewan Soil Nutrient Supply

Hammermeister, E.H. and C. Ball. 2011. 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 2011, 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.
