Busting nitrogen loss with late in-crop application

If you’re about N loss, you may consider a late boost

Corn growers may want to wait on nitrogen application, particularly in a wet year. A nitrogen application at the end of June or early July will help limit nitrogen loss and better time it to when the plant is actually looking for the nutrient, speakers said during a recent field day at the Canada-Manitoba Crop

Soil N trend surprising

A dry summer could have left a nice bonus for you in your fields

AGVISE Laboratories says the trend this fall is towards higher levels of residual nitrogen in Manitoba soils. The Northwood, North Dakota company says an early harvest has allowed producers to get a jump on fall soil testing, and its accumulated data from more than 3,000 wheat fields already. That’s been surprising to many producers who

Sierra mix corn variety found in Oaxaca, Mexico.

Corn that finds its own nitrogen

Researchers have known about it since the 1980s but were only recently able to analyze it

Is it possible to grow cereal crops without having to rely on energy requiring commercial fertilizers? In a new study publishing August 7 in the open-access journal PLOS Biology, researchers describe a newly identified corn variety which acquires nitrogen by feeding its sugars to beneficial bacteria, which can in turn take up nitrogen from the


MPSG production specialist Laryssa Stevenson talks about the benefits and risks to a rescue nitrogen application in soybeans during the Manitoba Pulse and Soybean Growers SMART Day event in Melita July 17.

Poor nitrogen uptake has soybean growers pondering rescue application

Lack of moisture has also meant lack of nodules and poor nitrogen fixation for some soybean fields, leading some to consider a mid-season fertilizer pass

More soybean fields are trying to shake off the impact of a dry spring on nitrogen uptake this year. Laryssa Stevenson, western production specialist with the Manitoba Pulse and Soybean Growers, told a SMART field day here last week that she has heard of more growers struggling with nitrogen deficiency this summer, which she blames

A provincial oilseeds specialist is recommending canola growers adjust their seeding rate based on seed size and fertilizer placement.

Canola producers put on watch against seed burn

Some cereal fields in Manitoba are seeing seed burn, and Manitoba Agriculture is warning farmers to guard against the same problem for canola

The weather isn’t the only thing that’s hot. Manitoba Agriculture is warning canola producers to avoid banding fertilizer too close to the seed row as continuing dry conditions raise the risk of seed burn. “Adjust your seeding rate based on your seed size and your fertilizer placement strategy,” provincial oilseeds specialist Dane Froese advised during

Industry still looking for new NH3 tank rule break

Fertilizer Canada and the Canadian Association of Agri-Retailers (CAAR) say there will be enough anhydrous ammonia nurse tanks available to supply the fertilizer to farmers during this growing season. New Transport Canada regulations came into force Jan. 12, which affect the frequency of hydrostatic testing and visual inspection of ammonia nurse and applicator tanks and

Nutrien sees demand growth cooling, margins shrinking

Reuters — Nutrien, the Canadian fertilizer and farm supply dealer created from the merger of Agrium and PotashCorp this year, said it expected demand growth for potash in China and India to cool down in 2018. Nutrien, the world’s biggest fertilizer company by capacity, also said higher input costs would shrink nitrogen and phosphate margins.
