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.

While I’m a big supporter of precision ag as a means to collecting data for better decision making, I was reminded recently we can’t lose sight of the fundamentals like soil testing, as boring as this may sound to growers. A 2015 Olds College survey by students highlighted the need to keep soil testing front and center. Forty six percent of respondents only soil sample occasionally. Seventy-eight percent of farmers that use soil sampling see the information as useful, and 22% responded say they would consider zone sampling in the future.
Why Farmers in Western Canada Use or Don’t Use Soil Sampling as Part of Their Nutrient Management Planning

  • 78% of farmers had soil sampling done sometime in the past
  • 22% had never used soil sampling
  • 23% soil sample every 2-3 years
  • 29% soil sample to [...]

Every few years it seems base saturation rises as a winter topic as a means of making fertilizer recommendations. While base saturation has been used to determine whether a soil should be limed or not, it’s not a soil testing index, nor should be accepted broadly as an indicator for nutrient fertility. Developed for low CEC soils and highly weathered low pH soils, but not meant for many areas in Canada including Western Canada

CropLife Canada has partnered with industry, academia, and government experts to create a website, to offer resources, and promote strategies for managing disease, insect, and weed resistance.

Herbicide & Cover Crop Strategies for Managing Glyphosate-Resistant Fleabane

Weed herbicide resistance is one of the most serious management  issues ratedfby growers, agronomists and researchers . In Eastern Canada at the top of that list is glyphosate-resistant fleabane (GRFB). First identified in southern Ontario in 2010, GRFB has spread like wildfire across Ontario and is now identified in other areas including Quebec. Fleabane seeds are small, airborne, and stick to clothing, equipment, animals. A single mature plant can produce up to 250,000 seeds/plant. Most fleabane biotypes are glyphosate-resistant, but other biotype herbicide resistance to group 2, 2 & 9, and 22 exist.Good control options exist in corn and wheat, but is problematic in soybeans.

A Mennonite neighbour of mine operates a small engine business. He services a lot of small engines from different equipment, and he commented recently that the most common issues he sees in problems with the motor could have been avoided by regular service according to the owner’s manual. The Honda gas engine on the Wintex is a commercial quality motor that can provide many years of reliable, trouble-free service. Refer to your owners manual for scheduled maintenance including these items

  • Changing the engine oil at first 20 hrs and then every 6 mths or 100 hrs
  • Air filter service/replace
  • Clean sediment cup
  • Spark plug replace yearly or 300 hours
  • Drain fuel or use a fuel stabilizer. Check if the fuel tank is clean
  • Service fuel filter
  • The Start recoil is in good condition & operates smoothly

Manitoba Agriculture has developed a simple Phosphorus (P) spreadsheet calculator that allows users to input yield information and applied P during a rotation. A P balance is determined based on crop removal values, to show if soil P is being built, maintained or depleted. Phosphorus from manure applied during a rotation allows users to balance P over cropping cycle.

Phospohorus Balance Calculator (XLS)

Declining soil test phosphorus in the praries has increased interest in pushing P rates higher, following a 4R approach. Where high rates of P are required, side-banding of most or all of fertilizer P should be side-banded. Seed placed P did not provide a better canola crop response even at low rates compared to side-banded. More
