In the early days of fertilizer use on the Canadian Prairies phosphorus was the only game in town- mostly 11-48-0. “If in doubt use 11-48,” was the chant. Much work was done to find the amounts to use for various crops and soils and the best way to put it on. We thought we knew […] Read more
Simplifying phosphorus
Experts’ opinion on P fertilizer have changed over time, and are still changing now
Looking for solutions for fusarium
Fusarium head blight is on the rise, and Les Henry is looking for a solution
The title of this piece might suggest that the author is an authority on plant disease, but that is not true. For this I have my farmer hat on. There is nothing like a little skin in the game to force one to read the literature and learn. My rotation had been wheat/peas/wheat/canola for 15 […] Read more
Planning fertilizer for forage crops
Some food for thought on fertilization to establish forage crops in your fields
Forage crops are sometimes treated as the neglected child. Once it is established, come along with a haybine if there is enough rain to make a crop. If it continues to rain after the bales are off maybe even come in to get a small second cut. Grass hay crops are often left to wither […] Read more
Make sure you mind your fertilizer Ps and Ks
The fertilizer story — why a pound of phosphorus may not really be a pound of phosphorus
In a recent article I mentioned a classic old Alberta document that talks about managing Gray Wooded soils — low in fertility and organic matter. I pointed out that when the old boys had data about rates of application of phosphorus and potassium, they meant just that, P and K, not P2O5 and K2O — […] Read more
Les Henry’s prairie stubble soil moisture map
In the map of November 2016 soil moisture, there are no “very dry” areas
As usual, this map gives only a very general indication of the soil moisture situation on the Canadian Prairies as we went into freeze up November 2016. It can be summed up in a word WET. To make a soil moisture map it is essential that a good database of rain records from many stations […] Read more
90 years of Saskatchewan farmland prices
Saskatchewan land prices have been on the move since 1968. What’s next?
Readers have been asking for an update on farmland prices but I was having trouble accessing the required data. Thanks to Terry Bedard of Saskatchewan Agriculture for sending me recent average price data. This data is just for Saskatchewan. Alberta land prices are changed by many factors that are not related to what is grown […] Read more
A convert to long-term experiments
Soil fertility is a long-term prospect that calls for long-term approaches to research
In my younger days I was not a fan of long-term experiments. Almost all were on Federal Research stations with good soils and plot practices that did not always relate to farm fields. But recent information coming from long-term experiments has changed my mind. Worldwide, the longest experiment is the famous Broadbalk field at Rothamsted […] Read more

40 years of writing for Grainews
Les Henry reflects on his 40 year tenure in the pages of Grainews
It is hard to imagine that 40 years have slipped by since I scribbled my first piece for Grainews in 1976. It was “Nitrogen: When, what kind and how much to apply.” Today we would call it the 3 Rs: Right time, right source and right rate. The 4th R, right placement, was yet to […] Read more
Potashium: fertilizer mergers
In the wake of announced mergers, a look at the history of Prairie fertilizer
The recent proposed merger of Potash Corporation of Saskatchewan and Agrium has generated much discussion about the merits or pitfalls. I have little knowledge of the backroom dealings of huge corporations but am uneasy about companies becoming too large and competition dwindling. The final decision will be up to the Government of Canada Competition Bureau […] Read more
