Selenium sits on thinnest line between health and hazard

Agronomy Management: Removing selenium from water is costly and difficult at best

There are increasing concerns about the potential effects of a proposed coal mine development in southern Alberta and the impacts selenium could have on the environment in southern Alberta and into Saskatchewan. The proposed Grassy Mountain Coal project would be an open-pit mine built on a former coal-mining area about seven km north of Blairmore […] Read more

When stock water levels drop, a solar water system can help extend the quantity and preserve quality in the remaining water.

Prepare your ranch and business plan for bouts with drought

A Little Bit Western: There are ways to extend feed and water — but do so with caution and monitoring

In late summer I was invited to the Canadian Beef Industry Conference in Saskatoon to share my perspective on navigating drought. I would prefer covering a more cheerful topic, but as a fourth-generation Palliser Triangle dweller who resides on a ranch abandoned not once but twice by its former occupants, I’ll admit I’ve got experience […] Read more


Your fearless columnist tosses the cell for electrical conductivity (EC) measurement into the Montreal River at Saskatchewan Highway 2 in July 2005. Results are recorded in a notebook and all is carried in a briefcase. I have notebooks like that all the way back to 1982. At this location, water EC is 260 uS/cm. In the north, water is mostly low EC; the standard for comparison is the South Saskatchewan River system that runs through Saskatoon, with an EC of about 450 uS/cm at 25 C.

Water chemistry: a Coles Notes version

Soils & Crops: Conductivity and hardness of water samples show what you can use it for

First of all: readers who have Henry’s Handbook of Soil and Water can check out pages 124-125 for a detailed discussion of water chemistry, complete with calculations. Water is considered to be the universal solvent because it is capable of dissolving more substances than any other liquid. Therefore, one of the first things we might […] Read more

A hydrologist and a farmer draw water from a 30-foot sampling well in western Iowa, testing for nitrate and herbicides.

Nitrate down the well

Soils & Crops: If you move onto an old farmyard with an existing well, don’t drink the water without first getting it tested

This column has dealt with this topic several times over the decades we have been scribbling. Recent sources have raised the nitrate issue again. It deserves repeating once in a while, to make sure no more infants die from the blue-baby condition (methemoglobinemia). The link between nitrate-contaminated farmyard wells and blue-baby was first reported by […] Read more


How to maximize the efficacy of your crop protection products

How to maximize the efficacy of your crop protection products

For starters, ensure you have adequate water quality

No farmers want to unintentionally alter the efficacy of their crop protection products because of water quality pumped into the tank. However, farmers may do just that if they do not have their farm water source tested every year and take the appropriate actions based on the results of those tests. There are several factors […] Read more

This is the slough where the salt water changes shown in the table were measured. This photo was taken on July 29, 2013. The water level is now much lower.

Water monitoring: dull but necessary

Keeping track of all of the numbers is still necessary for decision making

Long-term monitoring of agricultural and environmental conditions and practices has been an important function of government agencies. It has been my experience in recent years that a lot of important monitoring functions have been reduced in scope or discontinued. In this column, I’ll describe a few examples of good monitoring and show the importance of […] Read more

Tips to help you protect your household water

The water that enters your home has a long journey from start to finish, and along the way, it can pick up a lot of contaminants. Once it reaches your municipal water treatment facility it is treated and distributed to the public. During this process chemical and physical processes are used to filter and disinfect […] Read more

Water chemistry: the Coles notes

Measure your water in the field before you use it in the house, the field or the barn

This piece is all about encouraging the energetic young folk that are advising farmers to measure it in the field when a water question comes up. There are many additives for spray water on the market but check the water source first. A change of water may be the best and cheapest route. Water chemistry […] Read more


Drought brings its own package of health risks for livestock

Drought brings its own package of health risks for livestock

Pests, toxic plants and disease can all thrive under dry conditions

With the current lack of runoff moisture and few spring rains across much of Western Canada, certain disease conditions may become more prevalent. It will pay to be extra vigilant this year when checking your herds. We commonly see more blackleg and all the other clostridial diseases in dry conditions. With shorter grass, cattle and […] Read more

Hard water hampers weed control

To get the most from the herbicides you’re spraying in your field, check your water quality first

A North Dakota State University extension specialist says the performance of some herbicides can be adversely affected by using hard water to prepare spray mixtures. According to Richard Zollinger, there are a variety of water quality issues that can impact herbicide efficacy, including the presence of clay, silt or organic matter in the water. But […] Read more
