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

The economic value of growing cover crops

Not all of the economic benefits of cover crops can be measured easily, but it’s worth a try

The first question that comes up when cover crops are discussed is “Do they pay?” Net returns from cover crops will be determined by what goals were set, what species were grown and other intrinsic benefits from the cover crop. In any business, net profit is the difference between costs and revenue. The two ways […] Read more


Soil nutrients are in deficit after 2016

Soil nutrients are in deficit after 2016

Consider the toll 2016’s big crop took on NPKS when planning for 2017 fertility

Make sure you have a late fall or early spring soil test as a guide to plant your 2017 crop fertility program. After the 2016 growing season, this is even more important than usual, says Rigas Karamanos, a long-time soil specialists who is now a senior agronomist for Koch Fertilizer Canada. Karamanos says his message isn’t […] Read more

Getting the most from soil test reports

Getting the most from soil test reports

Ratings vary depending on crop type, yield goal and soil zone

When you understand your soil reports, you’re in a better position to develop fertilizer plans with your agronomist. All soil testing labs report the same basic information, but each lab has its own unique format. No matter what your report looks like, first, check the information at the top: your name, address, field name, etc. […] Read more



This is a feed barley crop at Spiritwood, Sask., in 1996, on Gray Wooded loam soil. This crop yielded 80 bu./ac. with no fertilizer in the year of seeding.

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


Crop diversity, rotational diversity and, if possible, getting animals on the land, are the ways to start building soil health.

Cover crops for better soil health

Cover crops can help build the “livestock” that lives in the soil and improves productivity

It appears that the idea of farmers improving the soil is starting to take hold. The Western Canadian Soil Health Conference was held in Edmonton, Alberta, the first part of December 2015. Nora Paulovich and Tom Fromme, co-chairs on the organizing committee, did a wonderful job pulling speakers together and organizing it. It started at […] Read more

For 40 years, Grainews and Les Henry have shared ag research with farmers

Looking back on Les Henry’s 40 years of Grainews columns causes me to reflect on how most things have improved in Prairie agriculture, though a few haven’t. I got my start as first field editor of Grainews in 1976, around the same time as Les started writing his columns. One of my first stories was on the proper […] Read more


Dean Glenney found an abundance of earthworm holes in the non-trafficked areas of his field.

CTF benefits soil over time

Fencerow farming system increases corn yield and changes farmers’ soil biology

Fifteen years ago, when the bin-full alarm went off on Dean Glenney’s combine as he harvested his corn crop near Dunnville, Ontario, he had no idea what was going on, and he certainly didn’t expect the record yield of 236 bushels per acre he pulled off the field that season. Since then his yields have […] Read more

The project may look simple from above ground, but underground many sensors and scales take complex soil measures.

Soil health sensor project largest in North America

A new $2-million soil health research project aims to figure out the impact of different cropping systems on the environment. Research will also be conducted on crop productivity relating to soil health. The result should be new knowledge on productivity of traditional cropping systems versus those with cover crops. The project, at the new Soil […] Read more
