Field day attendees get a look at the pivot-mounted radiometers, one of AAFC’s efforts to nail down variable-rate irrigation and mapping at Carberry’s CMCDC this year.

Potato researchers delve into variable-rate irrigation

Potato producers are hearing more about variable-rate technology, but researchers at Carberry are trying to dig up some concrete numbers on the technology

If there’s a perfect recipe for success when it comes to variable-rate irrigation in potatoes, the researchers at the Canada-Manitoba Crop Diversification Centre (CMCDC) are still trying to find it. The idea of variable-rate irrigation is hardly new. As early as 2012, news of field trials was coming out of Alberta, although one of the

Soil N trend surprising

A dry summer could have left a nice bonus for you in your fields

AGVISE Laboratories says the trend this fall is towards higher levels of residual nitrogen in Manitoba soils. The Northwood, North Dakota company says an early harvest has allowed producers to get a jump on fall soil testing, and its accumulated data from more than 3,000 wheat fields already. That’s been surprising to many producers who


Straw being loaded off a field in central Manitoba. 

Feed your straw to the herd or feed the soil instead?

How much of a nutritional dent does baling straw make when that residue could have been chopped and spread?

Livestock producers have been scrambling for their neighbours’ straw, but growers may have been reluctant to let it leave the field. Attractive straw prices went head to head with the desire to chop and spread as growers weighed the balance between a secondary income and the cost of exporting those nutrients rather than working them

Manitoba Agriculture soil management specialist Marla Riekman wants farmers to consider “tillage rotation.”

Consider tillage rotation for improved soil management

High-speed, aggressive tillage can erode fields, especially in hilly terrain

There’s crop rotation, herbicide rotation and now Marla Riekman is advocating for tillage rotation. “There is the idea of rotational tillage where you can use some of your tillage options and use them in the most appropriate spots in your crop rotation,” Manitoba Agriculture’s soil management specialist said in an interview Sept. 7. Riekman isn’t


Tillage erosion is gaining attention around the world as researchers get a better understanding of how tillage can move soil.

Get your topsoil moving

Landscape restoration can offer immediate yield boosts

If you farm in the Prairie pothole region, you’re dealing with some yield loss due to tillage erosion, says Marla Riekman, land management specialist for Manitoba Agriculture. The good news is there’s a relatively easy way to restore that lost yield potential: simply move the eroded topsoil back up the slope. Riekman was at this

The researchers studied Acmispon strigosus, a plant in the pea family that is native to the southwestern United States.

It’s not just soil microbes that set crops up for success — it’s the right ones

Beautiful things can happen when plants surround themselves with the right microbes, according to researchers at the University of California (Riverside). They looked at Acmispon strigosus, a plant in the pea family, and found a thirteenfold growth increase in plants that partnered with a highly effective strain of the nitrogen-fixing bacteria Bradyrhizobium. The ability of

Our History: May 1994

Both the U.S. Midwest and the Canadian Prairies suffered from too much moisture in 1993, but things had switched by the spring of 1994. This photo in our May 26 issue showed a ditch full of topsoil north of Carman, the result of gale-force winds on May 17. A recently bulldozed shelterbelt could be seen

Cool soils? Seed cereals, field peas first

Manitoba soil temperatures are increasing, but vary with soil type and location

If soil temperatures are cool plant cereals and field peas first, says Manitoba Agriculture Farm Production Advisor Lionel Kaskiw, based in Souris. Soil temperatures are warming, but are still variable depending on soil type and location, he said during the Westman Crop Talk webinar May. 1. Soil temperature readings are available at 109 Manitoba Agriculture

Four ways to increase your organic matter

A question that I hear a lot is, “How do cover crops fit into a grain operation?” Lots of grain farmers have no desire to get into the livestock business and no interest in producing hay. But many have some soil issues that need to be addressed. This can be done by buying more iron

Six factors to consider if your soil moisture level is low

To date, all indications are pointing to a dry spring, given the below-average precipitation received in many areas of the Prairies this winter. There are exceptions to every rule of course, but a lot of farmers had relatively dry soils going into winter, so we asked some agronomists and provincial crop experts what factors could
