Should you be planting green manure?

Researchers see planting and terminating ‘green manure’ as an alternative to summerfallow

By
Researchers at Agriculture and Agri-Food Canada as well as the Saskatchewan Ministry of Agriculture have published two recent studies about the effects of green manure on farmland in the Prairies. In one study specifically, the researchers looked at using green manure as an alternative to summerfallowing. Green manure “is a crop that is specifically planted in order to be terminated, […] Read more
On the left is a root of a sugar beet grown in fine sandy loam soil, showing root stratification in the second and fourth foot of soil where layers of clay were encountered. From Weaver, 1926, Root Development of Field Crops. The wheat and wild mustard graphic on the right shows root competition between Marquis wheat (on the left, with roots marked 1, 2, 3 and 4), and wild mustard, 22 days after emergence. (This graphic is from Pavlychenko and Harrington, 1937: Ecology Vol. 18 No.1 Pages 62-79.)

Getting to the root of the matter

For a look at the big picture, the ‘old’ research on roots is still relevant today

By
Plant roots are receiving more attention of late and well they should. Roots are the foragers that deliver water and nutrients to the plant, but too often our attitude is “out of sight, out of mind.” With the current interest in many plant species, cover crops and soil health, much of it comes down to […] Read more
If producers really want to try and get moisture levels down in their soil and decide to till, they need to think carefully about their phosphorus needs, says Dr. Mario Tenuta.

Tillage is tempting, but treacherous

While tillage can get you in the field faster, it can also disrupt networks in your soil

By
Many farmers across Western Canada have been struggling with wetter than normal conditions over the past few years. This spring many will again be facing soils that are close to the saturation point and puzzling over how to deal with them. Some farmers may turn to tillage to help dry them out, or at the very least to smooth […] Read more

Precision ag may not work on your farm

In the field, precision ag does not yet live up to the hype that has surrounded it

By
If we go into a farm meeting and ask how many are using auto steer almost all hands go up. If you ask how many are using variable rate only a few respond. The uptake has been slow and many techies think that farmers are slow adopters. Guess what folks: if it works farmers are […] Read more
Smart Solutions collects all the data on seeding operations, for example — what and when it was seeded, fertility, in-crop treatments all by field and by soil zone.

So much more than just a rain gauge

Farmers Edge weather info 
service connects the dots of 
precision farming data

By
If you thought GPS and auto steer was a step forward in farming, check out the precision farming package Farmers Edge is launching this spring in Western Canada based around its on-farm, “field-centric,” precision weather data system. The weather station is just part of an overall integrated data collection package called Smart Solution. Weather information […] Read more

Coping with all those wet spring soils

After last fall’s moisture, spring seeding is going to require patience and flexibility

By
Patience is a virtue, but it’s not an easy one to practice, especially when it involves waiting for saturated fields to dry up so you can get out and seed this year’s crop. Last fall left many Prairie fields already saturated thanks to late fall rains and early snowfalls, and after a winter with heavy […] Read more
McGrath and helpers dig some soil pits along transect lines on native prairie pasture that is part of Round Rock Ranching to establish some baselines through nutrient and biological soil testing.

Are you a (soil) health nut?

Any treatments applied above ground will eventually affect what happens below your feet

By
I was eternally blessed to enter the University of Saskatchewan while Les Henry was still teaching at a time when we were “forced” to take at least an introductory soil science course. I learned a lot in that introductory course; mostly about how much I didn’t know (and how much Dr. Henry did). But more […] Read more

Planning fertilizer for forage crops

Some food for thought on fertilization to establish forage crops in your fields

By
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

Getting the dirt on 4R nutrient stewardship

Fertilizer Canada’s 4R nutrient stewardship research tour delivers valuable information

By
In the ever-changing world of farming, information is a more valuable commodity than the finest canola crop. Consequently, the recently launched webinar series “Across Canada Tour of 4R Nutrient Stewardship Research” sponsored by Fertilizer Canada is must-see viewing. The tour began last month in Alberta, where co-presenter Dr. Miles Dyck offered an overview of 4R […] Read more

94 is out there — don’t settle for average

Agronomics, fertility and overall nutrition can raise field pea yields as high as 94 bushels per acre

By
It was only a plot, and it wasn’t necessarily a realistic crop nutrient program most producers would consider following, but an ATP Nutrition demonstration at a Saskatchewan farm show last summer, showed Prairie farmers it is possible to produce an 94 bushel field pea crop. That 94 bushel yield, on plots at the Ag In […] Read more
