Ontario watershed study shows overapplication of phosphorus

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

Lake Erie plan’s farming recommendations released

A federal/provincial action plan to reduce phosphorus loading in Lake Erie has been released for public comment — and many of its recommendations will have implications for farmers in the Lake Erie basin. None of the numerous recommendations are particularly new or surprising and mostly call for using existing funding programs to encourage certain production […] Read more


Manitoba to axe limits on hog barns

UPDATED, March 20 — Manitoba’s restrictions on hog barn and manure storage construction are set to be shelved by way of an omnibus “red tape reduction” bill. Provincial Finance Minister Cameron Friesen on Thursday introduced Bill 24 for first reading. Among its 15 proposed amendments to various pieces of legislation, the bill would repeal two […] Read more

Phosphorus program aims to reduce Lake Erie nutrients

Chatham, Ont. — Henry Denotter’s farms near Kingsville, Ont. are close to the Wigle Creek, which flows into Lake Erie and takes with it any residues it pulls from nature and farmers’ fields. The Wigle Creek subwatershed, west of Leamington, has turned into ground zero in long-term research on how farmers can reduce phosphorus running […] Read more

New tool for managing nutrient run-off

Free downloadable tool for assessing phosphorus run-off risk and creating a 
customized mitigation plan will be available this spring

As more and more farmers, politicians and laypeople are coming to understand, nutrient run-off from farm fields into waterways is a very big deal. When not managed properly, nutrients from fertilizer and manure make their way into creeks, lakes, dugouts, and other water bodies. But a new tool to help mitigate phosphorus run-off risk will […] Read more

Mylar- and Kevlar-reinforced tanks house the micro-algae used to clean up GHG emissions. Liquefied poultry manure helps the micro-algae grow.

Call it a win-win: Curbing pollution with chicken manure

Scientists have found a type of micro-algae that gobbles up greenhouse 
gas emissions — and it has a taste for nutrient-rich chicken manure, too

Poultry manure and that annoying green slime which grows in our lakes each summer could hold the key to helping the province’s oilsands mining companies and coal-fired power plants clean up their act, while producing a valuable commodity in the process. Researchers have discovered a strain of naturally occurring micro-algae that can scrub 100 per […] Read more


Dealing with a lack of calcium in pregnant cows

Beef and forage specialist Barry Yaremcio does the math on providing this mineral 
to pregnant cows

When feeding cereal silage, greenfeed or swath grazing to pregnant cows, there can be a concern with a lack of calcium and magnesium. An added product can often be the solution. “In this situation, an added product should have more calcium than phosphorus,” said Barry Yaremcio, beef and forage specialist, with the Ag-Info Centre in […] Read more

Minogue: Rebalance your fields’ phosphorus bank accounts

While your crop rotations and your seeding practices have evolved into something your grandfather might not recognize, recommended phosphorous guidelines for Manitoba farmers haven’t changed in more than 20 years. Over the past year, Manitoba soil fertility experts came together to fill this gap. John Heard (Manitoba Agriculture, Food and Rural Development), Cindy Grant (Agriculture […] Read more


Wheat in study finds P where soil tests don’t

A long-term yield study in Saskatchewan shows wheat crops will use the phosphorus built up in soils over years of fertilizing — even where soil tests don’t show the nutrient is handy for use. While the results still need to be tested elsewhere, with other crops, the study’s findings may help Canadian farmers rethink how […] Read more

The recipe has to be just right when fertilizing your crops

Phosphorus and potassium work well when placed in the seed row — 
but nitrogen and sulphur are mobile

Nitrogen may be the first thing producers think of when they want to bump up their yield — but don’t neglect the other nutrients. “In order to get the maximum benefit out of all of our fertilizer nutrients, we need to have a balanced supply,” said University of Saskatchewan soil scientist Jeff Schoenau, who drew […] Read more
