Prairie farmers have done an excellent job shifting to direct seeding, continuous cropping, using much more diverse crop rotations and fertilizing crops adequately, along with various other good agronomy practices. This has very positively improved soil organic matter levels and improved soil health across all the soil zones of the Prairies.

Changes in cropping practices over time have significantly improved soil quality
Selenium: Agricultural, environmental and human concerns
Agronomy Management: From a water quality standpoint, health of rivers and lakes should be of highest priority
As selenium accumulates in soil over years, more Se will be taken up by plants, making crops less suitable or unsuitable for human or livestock consumption.
Understanding phosphorus, part 3: Developing fertilizer recommendations
Agronomy Management: It’s important to have adequate P close to the seed during the first six weeks of growth
Part 3 of 3. Prairie farmers spend over $1 billion annually on phosphate fertilizer; these three articles will hopefully assist with a better understanding of how soil P functions in soil, soil testing for P and then how to develop wise phosphate fertilizer recommendations.
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
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
One does not simply measure soil health
Agronomy Management: Just analyzing soil samples won’t give you the big picture
Over the past 40 years, Prairie farmers have made extraordinary strides in improving soil quality. Two major reasons were the shift from using summerfallow to continuous cropping, and the shift from conventional cultivation to no-till or minimum-till farming. Farmer adoption of these improved practices was gradual. Most famers were cautious and wanted to be sure […] Read more
Selenium sits on thinnest line between health and hazard
Agronomy Management: Removing selenium from water is costly and difficult at best
There are increasing concerns about the potential effects of a proposed coal mine development in southern Alberta and the impacts selenium could have on the environment in southern Alberta and into Saskatchewan. The proposed Grassy Mountain Coal project would be an open-pit mine built on a former coal-mining area about seven km north of Blairmore […] Read more
Drought preparedness through soil and crop management
After each dry year, adapt your drought plan based on your experiences and what you learned
As spring approaches, the agricultural community is becoming increasingly concerned about potential forecasts of drought across the southern Prairies. And rightly so; the print and electronic media have posted numerous drought-related articles. Wide areas of southern Alberta and southwestern Saskatchewan and their dryland farms, irrigated farms and ranching areas could be affected. But what helpful […] Read more
Managing irrigation with limited water
Some irrigation districts are advising users to brace for limits on available water
There is increasing concern with below-normal mountain snowpack and potential for limited irrigation water availability in 2024. Snowpack in mid-February was about 50 to 75 per cent of normal at most of the snow pillow monitoring sites in the Rocky Mountains of northern Montana and southern Alberta (visit the Alberta River Basins web page, then […] Read more
A decade of dry
Let's review the variability of weather and soil moisture at Lethbridge
Weather is often the greatest factor that influences crop production across the Prairies — in particular, growing season precipitation and level of heat. The southern Prairies, particularly the regions of the Brown and Dark Brown soil zones, have the lowest growing-season precipitation, in the range of 150 to 200 mm (six to eight inches) and […] Read more
