Is phosphorus management being lost in the fertilizer furor?

While there’s lots of talk about nitrogen, managing phosphorus remains a critical concern

By Don Norman November 7, 2022

[UPDATED: Nov. 15, 2022] Phosphorus management could fall off the radar as environmental messaging in agriculture increasingly focuses on climate change and nitrogen use. “Appropriate nutrient management for things like phosphorus is tremendously important and needs to remain an ongoing focus,” says Lynda Nicol, Manitoba Association of Watersheds (MAW) executive director.

Alum a useful tool to combat toxic algae

The chemical has been used in the U.S. to clear lakes of algal blooms but hasn’t seen widespread acceptance in Canada

By Geralyn Wichers December 23, 2019

It’s no magic bullet, but aluminum sulphate can significantly reduce toxic algal blooms in lakes, American scientist John Holz told conservationists at a Winnipeg conference on December 3. “It is a common tool,” said Holz, whose company HAB Aquatic Solutions, has done 104 applications of the product, also called ‘alum,’ in the U.S. Holz spoke

Nitrogen reduction not the path

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

By Manitoba Co-operator Staff January 8, 2018

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

Agriculture major contributor to Lake Erie algae blooms

Better on-farm management would go a long ways towards solving the problem

By John Greig April 12, 2017

There are two easily identifiable solutions to the Lake Erie algae blooms, said an American researcher, but success will require the co-operation of thousands of farmers. Jeffrey Reutter, a researcher at the Lake Erie island-based Ohio State University Stone Lab research station, has seen both the 1970s sewage-driven algae bloom, and the current blooms that

It’s well understood high phosphorus levels cause harmful algae blooms in Lake Winnipeg. What’s not yet well understood is precisely where they come from. A new project from the not-for-profit Lake Winnipeg Foundation (LWF) aims to find out. Its Community Based Monitoring project, operating as a pilot program in 2016, aims to co-ordinate the water

Early bloom raises algae poisoning concerns

The blue-green algae can be harmful or fatal  to humans and livestock

By North Dakota State University June 28, 2016

An early cyanobacteria bloom in Walsh County, North Dakota suggests livestock producers need to exercise caution with water sources this summer. Cyanobacteria, also known as blue-green algae, can produce toxins that are harmful to livestock, wildlife and people. Blue-green algae often occur in stagnant ponds or dugouts with elevated nutrient levels, forming large colonies that
