Nitrogen reduction not the path

Reducing how much nitrogen enters a lake has little impact on algal blooms, IISD researchers say

If you take the nitrogen out of the equation for lake algal blooms it turns out you really haven’t changed things at all. According to researchers at the Experimental Lakes Area, operated by Winnipeg’s International Institute for Sustainable Development, that’s because many of the algae responsible for the harmful blooms can turn around and fix

Nitrogen looking cheap across Prairies

CNS Canada — Farmers in Manitoba may be looking to fill up on nitrogen fertilizer this fall as prices reach lows not seen in over a decade. “One retailer I talked to said it was the cheapest nitrogen prices in 15 years,” according to Dan Mazier, president of Keystone Agricultural Producers. Prices also seem to

Broadcasting nitrogen in fall least efficient approach

It’s also the least environmentally friendly

Broadcasting in fall is the quickest and easiest way to apply nitrogen — and the least efficient. So why, anecdotally at least, does the practice seem to be on the increase? Bigger farms and a shortage of labour could be part of it. Moreover, nobody knows when poor weather will shut down field operations. And

"The main factor in residual nitrogen is always crop uptake, so when we have high yields of cereals and canola, as many have, the soil’s N is generally depleted." – John Heard.

Getting a jump on fall fertilizer

Recent rain may alter farmers’ plans, just like a dry year to date has

Recent rains in Manitoba will be welcomed by agronomists taking soil samples and farmers looking to do fall tillage work and fertilizing, according to one provincial soil specialist. John Heard, of Manitoba Agriculture, says fall soil tests remain the gold standard, in determining fertilizer needs for the crop. Agronomists often like to get a jump

Canada’s antitrust watchdog clears Nutrien merger

Canada’s Competition Bureau will put up no reasons why PotashCorp and Agrium shouldn’t be joined in Nutrien. The federal antitrust regulator on Monday issued a “no action” letter on the all-stock merger-of-equals that Saskatoon’s PotashCorp and Calgary’s Agrium proposed in September last year. The two companies, when merged, are to be headquartered in Saskatoon under

Farmers wait for fertilizer prices to fall amid oversupply

CNS Canada — As more fertilizer plants are built around the world and U.S. corn acreage shrinks, the typical thinking holds that prices for urea and nitrogen should fall, but that hasn’t been the case so far for Canadian farmers. “They’re more on the steady side,” said Todd Lewis, president of the Agricultural Producers Association

Heavy reliance on inputs diverts cash

Nitrogen use can’t keep increasing if greenhouse gas emissions are to fall

There is no way around it, according to Darrin Qualman, reducing carbon emissions will require a hard look at the use of nitrogen fertilizers. Speaking via Skype at the regional conference of the National Farmers Union (NFU) in Portage la Prairie last week, Qualman said the role of agricultural inputs can’t be ignored when it

Enhancing N efficiency

There are products available to protect you from nitrogen loss, 
as well as management techniques to apply

Leaching deep into the ground, gassing off into the atmosphere, soil denitrification from microbial activity — all ways you can lose your valuable nitrogen fertilizer. Finding ways to reduce these losses and help producers get more value from their N fertilizer is crucial, and that begins with understanding how these losses occur, said researcher Fabian
