A soil scientist collects a sample from a test plot. The zero- to six-inch depth should be sampled separately from deeper samples to accurately determine P fertilizer requirements.

Understanding soil phosphorus, Part 2: Soil testing for plant-available P

Agronomy Management: The proper test for your soil and region can help answer questions your plants’ roots will ask this season

In my previous Grainews article, I discussed soil phosphorus (P) cycling in soil, effects of crop rotations and fertilizing on soil P, and how crops take up soil P. In this article I’ll discuss soil tests used to estimate plant-available P. Next issue, we’ll discuss how to develop wise phosphate fertilizer recommendations for your farm. […] Read more

It’s well documented that if a micronutrient is missing or deficient, your expected yield could crash.

Soil fertility, revisited 

Practical Research: The history of crop production on the Prairies was one of nutrient extraction at an alarming pace

Soil fertility: a simple concept that requires long and well thought out answers. There are lots of articles on soil nutrient testing, along with many procedures, methods and interpretations.  Early on in the 1970s with Alberta Agriculture, my colleagues and I were very surprised with the answers to the soil testing questions we asked. A […] Read more

Understanding soil phosphorus, part 1

Agronomy Management: Rotations and fertilizer management have dramatic effects on pools of organic and inorganic P

Farmers and agronomists are very aware that phosphorus (P) is an essential element needed for optimum crop production in Western Canada. Most soils used for annual crops in Western Canada are very low, low or medium in plant-available soil P and are responsive to added P fertilizer. As a result, phosphate fertilizer use is second […] Read more



About 50 per cent of rye grown in Prairie Canada is estimated to come from newer hybrids first grown in 2014.

Practical Research: Growing it in soils with adequate levels of available copper is one way to go

Yes, it can be done, by following these directions. Of course, there will be skeptics, but I am dealing with the facts and not concocted opinions. First of all, if you read my previous articles in Grainews, you will come to the factual opinion that wheat, barley and oats undergo closed pollination — that is, […] Read more



Variability across a farm, or even within a field, can complicate data analysis for a producer.

Dollars from data

Improving the quality of the quantifying can help improve bottom lines, nutrient management, yields and decision-making

Unlocking the full strength of your data can turn small changes into bigger returns, and smart, localized insights can boost a farm’s bottom line, Brunel Sabourin of Antara Agronomy says. Sabourin was speaking to an audience of farmers and agronomists at St. Jean Farm Days, an agricultural event at St. Jean Baptiste, Man., about 60 […] Read more
