The role of enhanced efficiency fertilizers in nitrogen fertilization 

Crop Nutrition: Maximum crop production cannot be achieved with fertilizers and amendments alone

When trying to enhance crop production with fertilizer, we first need to answer the following questions: What crop yields are possible and what fertility and moisture are required to get there?   Crops exhibit different water use efficiency in every part of the Prairies. Water use efficiency is also weather dependent and when combined with best […] Read more

How plants conserve moisture in dry conditions

How plants conserve moisture in dry conditions

Plants do best when they have a little more moisture than they immediately require

In order to take in carbon dioxide to perform photosynthesis, a plant loses water vapour to the atmosphere as the stomata open. To counteract this, a steady supply of water is needed — hence what’s called the “transpiration paradox.”


Leaving taller standing stubble in a field increases its aerodynamic roughness heading into later fall and winter.

Farmers can get creative to manage water efficiency on Prairie fields

Growers often dismiss the unpredictability of precipitation as pure luck — but they can stack the odds in their favour with the right strategies. “There’s a lot of different dynamics going on with the water balance in the Prairies,” says Phillip Harder, research director and hydrologist at Croptimistic Technologies. In addition to summer rains during […] Read more

Shorter tubs protected by an electric fence wire give calves a chance to drink and learn about water.

Creating calf creep water tubs

Calves get their own water source while their trough is out of order

This spring we had to find a way to supply water to our baby calves. The pastures where we have our cow-calf pairs in the spring and early summer are fenced away from the creek, to avoid the risk of having a young calf swept away by high water. When we first moved onto this […] 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

More than half of world’s large lakes drying up, study finds

Gains in Great Lakes, Lake Winnipeg come from runoff, rainfall

London | Reuters — More than half of the world’s large lakes and reservoirs have shrunk since the early 1990s, chiefly because of climate change, intensifying concerns about water for agriculture, hydropower and human consumption, a study published on Thursday found. A team of international researchers reported that some of the world’s most important freshwater […] Read more

Feds open up consultations for sustainable ag strategy

Producer groups to have reps on advisory committee

The federal government has enlisted farm groups on the ground floor of consultations toward development of a long-term strategy to “amplify” the adoption and use of sustainable practices in agriculture over the next year. Agriculture Minister Marie-Claude Bibeau on Dec. 12 announced the launch of public consultations on strategy development, running from now through March […] Read more
