Top Soil Sample Depth Needs to be Consistent

Quality soil sampling is critical to correct interpretation of results. We stress to clients this point and write often about collecting and interpreting results.  This has become even more critical as agronomists and growers adopt more precision 4R nutrient management. A few years back AgVise lab completed a demonstration project on the effect of sampling depth for several nutrients. The project had 7 sampling points and 4 depth comparisons at each point. Soil Samples were collected with a Wintex 1000. Twelve cores per point were collected perpendicular to the planted rows of soybeans. The field was a well-drained sandy loam – loam texture, conventional tillage. The data indicated that phosphorus, potassium and zinc levels decreased with depth. Phosphorus & zinc move very little in soil so results were not surprising [...]


We are very much looking forward to our Western Canada trip, Aug 2-14th to speak and attend AgSmart, Aug 10 & 11, in Calgary. Along the way we will be visiting Agri-businesses for demonstrations of our Wintex soil samplers and eBee Ag drone. Most of our trip will be along the TransCanada highway, however we would sure be happy to arrange a visit and demo if at all possible.
