Fall 2018 soil nutrient supply rates, what do the trends show?

Abstract

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 2018 PRS® soil analysis in comparison with the previous two years. Soil supply rate data for N, P, K, and S was measured using PRS (Plant Root Simulator®) Probes used by Western Ag Professional Agronomy and Western Ag Innovations.
