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 Dave Bedard, GFM Network News March 24, 2021

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 Madeleine Baerg September 2, 2020

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

In parts of the field, wheat plants were pale, shorter and had smaller heads than the healthy-looking wheat. Maturity was delayed. Tissue tests would show the truth.

There’s a new phos in town

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

By Leeann Minogue October 15, 2019

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 Kevin Poole March 4, 2019

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 Lisa Guenther March 16, 2018

*[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 GFM Network News June 1, 2017

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

If producers really want to try and get moisture levels down in their soil and decide to till, they need to think carefully about their phosphorus needs, says Dr. Mario Tenuta.

Tillage is tempting, but treacherous

While tillage can get you in the field faster, it can also disrupt networks in your soil

By Angela Lovell April 20, 2017

Many farmers across Western Canada have been struggling with wetter than normal conditions over the past few years. This spring many will again be facing soils that are close to the saturation point and puzzling over how to deal with them. Some farmers may turn to tillage to help dry them out, or at the very least to smooth […] Read more

Simplifying phosphorus

Experts’ opinion on P fertilizer have changed over time, and are still changing now

By Les Henry April 7, 2017

In the early days of fertilizer use on the Canadian Prairies phosphorus was the only game in town- mostly 11-48-0. “If in doubt use 11-48,” was the chant. Much work was done to find the amounts to use for various crops and soils and the best way to put it on. We thought we knew […] Read more
