Human Waste Could Be Phosphate Source

Human excreta could have a key role in securing future food security, helping prevent a sharp drop in yields of crops such as wheat due to a shortage of phosphorus inputs, a U.K. organic body said Nov. 29. “It is estimated that only 10 per cent of the three million tonnes of phosphorus excreted by

Phosphorus Depletion An Ongoing Concern

The excess moisture that has plagued Manitoba’s Interlake forced Bragi Simundsson to cut back on his organic operation last year. “If you can’t cultivate for over a year, you’re pretty much beat trying to be organic,” says Simundsson, who had as many as six quarters of his 2,000-acre mixed grain farm near Arborg certified. Organic


Doing The Right Thing – for Aug. 19, 2010

Governments, although they usually mean well, make mistakes. And when those errors are incorporated into policy, they can have lasting repercussions. Such was the case in the mid-1990s when the Manitoba government made the ill-fated decision to regulate manure applications to farmland on the basis of nitrogen content. The error was an honest one. The



MZTRA Farm Tests Jumpstart Inoculant On Canola – for Aug. 12, 2010

An Agriculture and Agri-Food Canada researcher has launched a study to find out whether Jumpstart really works. Ramona Mohr will be examining how the phosphate-solubilizing seed inoculant containing the naturally occurring fungi Penicillium bilaii, will affect growth, P uptake, yield and quality of canola at the MZTRA farm, and a handful of other sites in

No Till No Silver Bullet For Lake Winnipeg Phosphorus Loading

It has long been a commonly held belief that zero tillage is a good way to keep phosphorus out of watersheds. But the latest research at South Tobacco Creek, near Miami, shows that the soil conservation practice aimed at covering up bare dirt with crop residue may be leading to more of the nutrient leaking

Noxious Or Necessary?

Phosphorus is not an evil pollutant – in fact it is a foundational building block for the DNA and RNA of all living things, even viruses, and is absolutely necessary for plants to capture energy of the sun through photosynthesis. “A reporter asked me a year ago, ‘Is there a substitute for phosphorus?’” said Flaten.


Looming Phosphorus Shortages Require Change

Farmers have found an ally in a new report from the International Institute for Sustainable Development (IISD), which says the responsibility for better phosphorus management cannot be carried by agriculture alone. The report shifts the focus from phosphorus as a noxious nutrient that must be regulated to prevent it from damaging the environment, to phosphorus

Options Abound For Improving Phosphorus Management

“The underlying problem leading to food waste stems in part from consumer behaviours supported by an economic system built to produce more than we need.” Anew report by the International Institute for Sustainable Development outlines several avenues that could be explored to improve phosphorus management: Another case for local food networks: “Cycling phosphorus exported in
