New fertilizer product aims to reduce tie-up, improve soil health
Vancouver-area company’s PhoSul product combines rock phosphate, sulphur and silica
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.”
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
How to develop sulphur fertilizer recommendations
Here’s how to take samples, interpret soil test results and more
In recent Grainews issues, I have discussed developing nitrogen (N), phosphorus (P) and potassium (K) fertilizer recommendations. I will continue with this theme and discuss developing sulphur (S) fertilizer recommendations in this column. Sulphur deficiency was first observed in Alberta more than 90 years ago on grey wooded soils. Over the past 30 years, sulphur […] Read more
Today’s biggest issues in soil fertility
When to broadcast, shallow band, deep band and top dress
Rigas Karamanos, a senior agronomist with Koch Fertilizer Canada, is one of the leading Canadian experts in soil fertility today. After speaking at hundreds of producer conferences and research symposiums, Karamanos says there are four major topics that come up again and again at every discussion of agricultural soil fertility. Broadcasting, shallow banding, deep banding […] Read more
New environmental rules expected to further lift diesel prices
MarketsFarm — Diesel prices in Canada and the U.S. have increased marginally ahead of winter, which is expected for this time of year — but in the New Year, prices on the farm will likely be higher than normal, as the ocean freight industry adopts new environmental standards. While a farmer’s demand for diesel is […] Read more
New marine fuel rules to boost diesel prices for at least a year, analysts say
Houston | Reuters — Global prices for diesel and marine fuels should rise by October ahead of a January switchover to new, very low-sulphur marine fuels, and remain higher for at least a year as refiners shift production to make more of the new fuels, analysts said. Marine fuels containing no more than 0.5 per […] Read more
Oil sanctions on Venezuela could benefit Canada
How Canada benefits from the oil sanctions the United States plans to place on Venezuela is contingent on the country’s ability to move its Western Canadian Select crude oil to U.S. refineries, said two oil industry experts. As part of an effort to effect regime change in Venezuela, U.S. President Donald Trump announced this week […] Read more
Price spike in sulphur leaves farmers, fertilizer makers sour
Winnipeg | Reuters — Phosphate fertilizer producers such as Mosaic Co. and PotashCorp are paying the highest prices in two years for sulphur, a key ingredient in their farm products, but farmers are the ones absorbing the extra cost. Higher sulphur costs, the result of tight global supplies and strong Chinese demand, come as fertilizer […] Read more
Greig: Lessons learned from Ontario crops’ pest pressures
The warmer winter and subsequent drought defined the 2016 cropping season in Ontario, resulting in more disease and insect pressures and then challenges managing them. Three agronomists gave an overview of the 2016 cropping season at the SouthWest Agricultural Conference in Ridgetown, outlining challenges and wins for the year. Leanne Freitag, Cargill’s manager of agronomy […] Read more
