Mario Tenuta, professor of applied soil ecology at the University of Manitoba predicts, among other things, that anhydrous ammonia and urea — popular nitrogen fertilizers — will be banned because they produce too much nitrous oxide — a powerful greenhouse gas.

In the battle to mitigate global warming farmers’ nitrogen use will be scrutinized

But soil scientist Mario Tenuta says there are things farmers can do to help themselves

The fight to control global warning will bring about big changes in how Manitoba farmers farm, says Mario Tenuta, professor of applied soil ecology and chair and adviser of the B.Sc. Agroecology Program at the University of Manitoba. “I predict eventually they will outlaw anhydrous ammonia and urea and replace it with high-efficiency (nitrogen) fertilizer,”

Keep your fertilizer on your land and out of the spring run-off

As the crop comes off some farmers are already thinking about next spring — specifically about getting a jump on things by fertilizing this fall. There are lots of compelling reasons to follow this strategy. Fertilizer prices tend to be lower this time of year, and spreading the workload out lets them get the crop

How much nitrogen could a wood chip chuck?

Researchers investigating wood chip bioreactors under Manitoba conditions 
say half the nitrogen in tile drainage run-off could be captured

Often considered a byproduct of forestry and landscaping, wood chips could also become central to decreasing nitrogen run-off from tile drainage systems. Dipping his hand into a plastic container full of wood chips at the Agriculture and Agri-Food Research Centre in Morden, Steve Sager said that increased use of tile drainage in Manitoba, as well

Agrium, PotashCorp in merger talks

Canadian fertilizer giants Agrium and PotashCorp confirmed Tuesday they’re in “preliminary discussions” toward a possible merger-of-equals. Calgary-based Agrium and Saskatoon-based PotashCorp emphasized in separate statements Tuesday that no decision has yet been made on whether to go ahead with such a merger and no agreement has yet been reached. “There can be no assurance that

Fertilizer prices look to rise by late summer

CNS Canada — A rise in prices for soybeans and other crops could make fertilizer more expensive in the coming months, according to a major player in the industry. In the May market report from the Mosaic Co., the company credited the rally in agricultural commodity prices, the strengthening of key currencies and various Indian

Fertilizer maker Yara to cut costs, raise investments

Oslo | Reuters –– Norwegian fertilizer maker Yara plans to cut operating costs and raise investments to become more competitive and grow its business, it said in an update ahead of an investor meeting on Tuesday. The company raised its estimate for 2016 capital expenditure to 17.9 billion Norwegian crowns (C$2.8 billion) from previous guidance

Fertilizer expected to be pricier by springtime

CNS Canada –– Relatively cheap natural gas has helped push down fertilizer prices for Canadian farmers over the past winter, but that should change by springtime. One Manitoba farm leader noted urea fertilizer that went for $545 per tonne last August could now be acquired for $445 per tonne. “Phosphate fertilizer was going for $721



The size of the Gulf of Mexico dead zone in 2011. The coloured gradients indicate the oxygen levels that present in the water at that recorded time.

Fertilizer run-off is just one piece of the dead zone puzzle

More perennial crops and protecting wetlands would help reduce 
the low-to-no-oxygen zone in the Gulf of Mexico

It’s true that fertilizer run-off, sewage, and other pollutants from the Corn Belt have significantly boosted dead zones in the Gulf of Mexico. That’s because up to half of the fertilizer applied isn’t absorbed by crops, and in order to grow more food we’re using 20 times more fertilizer in the Corn Belt today than
