Promise of self-fertilizing attracts investment

Promise of self-fertilizing attracts investment

Bayer bets big on a future where crops are designed to fertilizer themselves

There are a lot of efforts underway to optimize and minimize fertilizer use in crop production. Precision agriculture tools are improving the accuracy of where fertilizer is placed so that as much of it as possible reaches the plants that need it. And researchers from at least two Canadian universities — Ottawa’s Carleton University and […] Read more

Soils and Crops: Even with modern ag technology, we’re still reliant on rain or soil moisture

As the combines started to roll this fall, many were very surprised at how hard the truckers had to work. While not a barn burner, the 2017 crop will go in the books for many as good, and considering the lack of rainfall some will say it is great. We all like to point out […] Read more


Different types of soil have different properties. University of Alberta research is focusing on measuring soil quality.

Controlling traffic to improve your soil

A new test offers another way to test soil quality improvements

It can be called “fractal hierarchical aggregation” or just “fractal aggregation.” Whatever the moniker, the new method of soil health testing promises to offer an important way to assess soil quality and land stewardship, says Guillermo Hernandez, an assistant professor at the University of Alberta. Hernandez is the lead researcher on a suite of projects […] Read more

Farm it like you’re ‘just’ renting it?

Farm it like you’re ‘just’ renting it?

Do farmers look after rented farmland differently than land they own? Should they?

We’ve all heard the term “drive it like a rental” but could that also apply to farmland? Is a farmer more likely to use conservation practices like no-till or variable rate technology, or apply more fertilizer and/or manure to improve the fertility on land he or she owns than on rented land? In April 2013, […] Read more


Tom King (left) from the soils science department at the University of Saskatchewan talked about plant nutrient and 4R field trials at Saskatchewan Agriculture’s Crop Diagnostic School in Indian Head in July.

Growing crops in saline soil

Sometimes dividing up the field is the best solution to salinity

The Saskatchewan Ministry of Agriculture’s Crop Diagnostic School is a great opportunity for farmers and agronomists to get outside for a hands-on, up-close look at plots, plants, insects and weeds. This summer, the School was held in Indian Head over two days in July. One of the many speakers, Gary Krueger, Saskatchewan Agriculture irrigation agrologist […] Read more

Measuring soil’s benefits from CTF

Measuring soil’s benefits from CTF

A new test offers a way to measure improvements from controlled traffic farming

It can be called “fractal hierarchical aggregation” or just “fractal aggregation.” Whatever the moniker, the new method of soil health testing promises to offer producers an important metric for assessing soil quality and land stewardship, says Guillermo Hernandez, an assistant professor at the University of Alberta. This spring he published a research paper demonstrating that […] Read more


In my asparagus patch, September, 2012. Planting date was May 2002.

Getting to the root of the matter

In the third of a three-part series, Les Henry looks at roots of field and garden crops

This is the final of a three-part series. In part 1 (April 11, 2017) I talked about the folks that provided very detailed diagrams of many plant roots to the depth needed to get the complete picture. Part 2 (April 25, 2017) was perennial pasture and hay crops and weeds and part 3 is field […] Read more

Figure 1. Roots of native sod of True Prairie in SE Nebraska. Each square in this figure is one square foot, for a total root depth of eight feet. The common names of a few of the plants are: Bc = side oats grama; K = Junegrass; B = blue grama; So = prairie goldenrod; S = needle grass. From: Plate A, after page 38 of Weaver, J.E. 1920. Root development in the grassland formation.

Back to the root of the matter

In Part 2 of a 3-part series, Les Henry talks about perennial crop roots

This is Part 2 of a three-part series. In Part 1 we talked about the folks that provided very detailed diagrams of many plant roots to the depth needed to get the complete picture. In this part, we’ll talk about perennial plant roots, and in Part 3 will be about annual crop plants. Read more: […] 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

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

Rape field, canola crops

How’s your moly doing out there?

Molybdenum was once known as ‘poor man’s lime’ for a good reason

Under the category “if it ain’t one thing it’s another” when it comes to crop nutrient requirements, the question is now being asked, “have you thought about the molybdenum levels in your canola and pulse crops?” Cereals need it too, but canola, peas, beans, lentils, faba beans, soybeans and others all have higher molybdenum requirements. Molybdenum, also often […] Read more
