Bioreactors in tiled fields could themselves benefit from draining
Bioreactors are meant to filter nitrogen from tile water to help with runoff nutrient loads, but drying them out from time to time might increase their effectiveness
Do farmers need to apply sulphur to their crops every year?
Research suggests this important nutrient hangs around a lot longer than farmers think
“In terms of the reactions with some of the other elements of the soil, particularly in soils that have a lot of calcium, it hangs around a lot longer than we think it does.”
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
Feeding dry fields
Prairie farmers find more than one way to optimize fertilizer efficiency, whether in dry growing seasons or in any growing season
Farmers and crop consultants in Western Canada have slightly different approaches to manage weather-related fertilizer application risks. With variable moisture, do you apply the full amount at seeding and hope for rain — or find another way? Most producers contacted by Grainews opt for some version of split fertilizer application when facing dry growing conditions […] Read more
Cover crops: enough already
The benefits are often 'blown up' while the challenges are understated
Cover crops is a topic with a lot of ink spilled in many farm publications in recent years. Some scribblers seem to imply that a farmer is a laggard and an environmental hazard if she/he is not using cover crops on a regular basis. Cover crops actually include a wide variety of cropping sequences, and […] Read more
Turning city waste into good fertilizer
Soil Management: Lystek International’s CFIA-registered fertilizer takes waste from sewage to nutrition
One man’s trash is another’s treasure. It’s a familiar idiom at the heart of a Canadian company’s process for turning municipal sewage into fertilizer. Faced with the challenge of dealing with sludge, Canadian municipalities have done everything from dumping it in landfills to letting it flow into the ocean. Lystek International, based in Cambridge, Ontario, […] Read more
The broad basics of your soil’s pH
Soil pH is complex, and has different impacts on the availability of different nutrients
Farmers frequently ask “What does soil pH really mean?” and “What effect does pH have on availability of nutrients in the soil?” Both are excellent questions! The effects of pH are complex and vary with different nutrients. However, some broad generalizations are useful to keep in mind when understanding soil pH and making nutrient management […] Read more
Soil testing more relevant than ever
If you don’t know what nutrients are in the soil it’s hard to meet your crop’s needs
To optimize crop yields, Ieuan Evans, a well-known western Canadian plant pathologist, urges farmers to get back to the basics — do a soil test and follow the recommendations. Evans, speaking to farmers at the Ag In Motion farm show near Saskatoon in July says farmers have been advised since the beginning of modern agriculture […] Read more
The value of wheat straw
It can be tempting to burn wheat straw, but that nitrogen is valuable
With five irrigation years in a row and with current adequate nitrogen and other fertilizer nutrients we have grown some big wheat crops with big straw left over. In 2014 some folks had problems with proper canola seed placement through the straw load on the surface. We might even hear the odd whisper about looking […] Read more
Synergy and the four Rs
To get the most from your fertilizer plan, consider the relationships between variables
It’s important to evaluate all four Rs of fertility collectively when considering the nutrient requirements of your crop. Changing any one R — right time, right place, right rate and right source — can profoundly alter the management of the others, says Dan Orchard, an agronomy specialist with the Canola Council of Canada. “Adhering to […] Read more
