How to make P management more sustainable

Phosphorus deficits are a problem on many Prairie farms. A Manitoba crop nutrition expert explains why — and has suggestions for what can help

By
Phosphorus has always been an essential nutrient in crop production. Maintaining the right P balance — ensuring there’s enough of it to sufficiently feed crops, but not too much of it so it runs off fields or seeps away to contaminate water bodies — is an ongoing challenge for Prairie farmers. Manitoba crop nutrition expert […] Read more

Phosphorus fertility studies reveal best placement

Proper placement of phosphorus fertilizer is crucial to meet the nutritional needs of plants

By
Like most Canadians these days, farmers are looking to get the most bang for their bucks. That’s especially true when it comes to applying phosphorus fertilizers to their fields. Jeff Schoenau, a professor of soil fertility at the University of Saskatchewan (U of S) and chair of soil nutrient management for the Saskatchewan Ministry of […] Read more
Phosphate being applied with anhydrous ammonia in a dual placement banding on a Manitoba farm last fall. Manitoba Agriculture soil fertility extension specialist John Heard maintains this is an effective application method because it places phosphorus within the soil away from potential runoff losses and the acidifying nature of anhydrous ammonia tends to increase the availability of the phosphorus to next year’s crop.

Get a head start on next year’s crops with these fertility guidelines, options and pro tips

Many Prairie farmers choose to apply fertilizers to their fields in the fall to save time in the spring — a strategy Farmers Edge agronomist Thom Weir believes makes good sense for a couple of reasons. “There’s lots of data that shows seeding early has a significant benefit to yield,” he says, adding that for […] Read more
Thanks to Jim Lundgren, who farms at Glenora, Man., about 85 km west of Morden, for this photo of his early start to spring tillage on March 20, 2021, owing to the recent absence of snow and/or rain in the area. Not that it’s a race, but is spring fieldwork already underway where you are? If yes, feel free to snap a photo and email us at daveb@fbcpublishing.com. (Photo courtesy Jim Lundgren)

Manitoba soil temperatures allow for spring fertilizer

Winter ban lifted, with cautions

By ,
Farmers across Manitoba are now cleared to apply spring fertilizers including livestock manure on their fields, thanks to sufficiently warm soil temperatures, the province said Tuesday. Though the winter nutrient ban has been lifted, the province cautioned producers to “assess current weather conditions and periodically check weather forecasts” if they’re applying anytime between now and […] Read more

Today’s biggest issues in soil fertility

When to broadcast, shallow band, deep band and top dress

By
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

TIMAC Agro is bringing a new type of phosphorus to Western Canada

By
When TIMAC Agro International’s Top Phos product was listed as a finalist in Ag in Motion’s Innovation Program, in the plant and soil science category, many western Canadian farmers were not familiar with the company. TIMAC Agro may be new to Canada, but it’s not a new company. “We are in 131 countries,” said TIMAC […] Read more

Seed-placed fertilizer blends for soybeans

Q & A with Nutrien Ag Solutions

By
Q: What’s the ideal seed-placed starter fertilizer blend for soybeans? A: Legume plants have a high demand for phosphorus. Phosphorus is critical in many lifecycle processes from photosynthesis to nodulation. Currently, many acres of soybeans are still grown without enough fertilizer to offset nutrient removal by the crop. This may lead to nutrient deficiencies in […] Read more

New phosphorus research for canola on the way

Canola removes more phosphorus from the ground than the recommended safe rate


By
*[UPDATED MAR. 19, 2018] Farmers face a fertilizer dilemma each spring. The current safe rate for phosphorus in canola is 17 to 22 kilograms per hectare (15.2 to 19.6 pounds per acre). With good moisture, the recommendation goes up to 28 kg/ha (or 25.0 lb./ac.). But canola typically removes more phosphorus than the recommended safe […] Read more

Ontario watershed study shows overapplication of phosphorus

By
Farmers in one Huron County, Ont. watershed are applying almost exactly the nitrogen needed by their crops, but more than 30 per cent more phosphorus than is needed. University of Guelph researchers reached the conclusions by analyzing multiple years of data collected by the Ausable Bayfield Conservation Authority during in-person interviews with farmers in the […] Read more
