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

Agrium bucks fertilizer sector trend with Q3 profit

Reuters — Canadian fertilizer and farm retail dealer Agrium on Thursday reported quarterly profit jumped nearly nine per cent, as higher sales volumes and lower costs helped it buck the sector’s trend of weaker earnings. Weaker currencies in fertilizer-buying markets such as Brazil and India are weighing down prices, leading rivals PotashCorp and Mosaic Co.

Slowdown in sales softens fertilizer market

CNS Canada — A lack of buying throughout North and South America has put fertilizer prices under pressure, but so far, no one is lining up to capitalize on the weakness, according to an industry watcher. “Farmers aren’t in the mood to buy fall fertilizer. I think they’re more uncertain this year than they normally

Is NH3 on its way out?

Sleek white anhydrous ammonia fertilizer tanks perched on wheels ready to roll out to farmers’ fields were once a common sight along rural highways. Not so anymore. The apparent case of the missing anhydrous tanks has some wondering if it’s just an aberration, or if it signals a quiet but significant change in farmers’ soil

The statistics prove it — higher yields with Manitoba maple syrup

It’s now easier than ever to sell snake oil, says University of Manitoba 
soil scientist Don Flaten

It’s easier than ever to sell snake oil as a fertilizer, supplement or replacement, so for farmers it’s “buyer beware,” warns Don Flaten, a professor of soil science at the University of Manitoba. “It’s what I’d call the Wild West,” Flaten told agronomists attending an Agvise Laboratories meeting here March 18. “With the Wild West

Ammonium sulphate seen tougher to find, afford

CNS Canada — A shortfall in production seems to have made granular ammonium sulphate, the prime fertilizer used by canola growers in Western Canada, relatively scarce just weeks away from seeding. “Last year (it was) $470 a tonne, now it’s $525 a tonne; if you can get it. Those were the words from my supplier,”

Too early to alter nitrogen guidelines

Solid manure applications may actually release more nitrogen over time, not less

The questions, how much nitrogen was applied and how much is available don’t have the same answer. Seven crops into a long-term study on nutrient management at the National Centre for Livestock and the Environment, researchers have found that current provincial guidelines for estimating nitrogen availability may not reflect reality when it comes using solid

Fertilizer supplies tight

Rail problems this winter and two nitrogen plant breakdowns tightened 
N and P supplies

Tight fertilizer supplies might put the kibosh on some farmers’ hopes for seeding early this year, industry officials say. Poor rail service this winter and two nitrogen plan breakdowns have combined to tighten fertilizer supplies to local retailers. “Essentially we are behind where we’d like to be at this time of the year,” said Clyde

Spring forecast calls for tight fertilizer supplies

But a late spring means more time to find alternatives

Fertilizer is in short supply in Western Canada this spring because of poor rail service and a breakdown at an Alberta nitrogen plant, says Keystone Agricultural Producers (KAP) president Doug Chorney. “The real thing you’ve got to do here is make sure you have your fertilizer in place and make arrangements with your dealer as
