Comment: How roots are shaped for success

The amazing development of root shape and why it could help protect crops from climate change

Plants may live rooted in one place, but the more scientists learn about plants, the more complex and responsive we realize they are. Plants are specialists, making the most of what is near where they germinate. Learning about the intricacies of plant life is about more than inspiring wonder in people, though. Studying plants is

The University of Manitoba’s Martin Entz, an agriculture professor and cropping systems specialist, suspects reduced tillage and organic production may not be mutually exclusive.

Can organic no till work in the field?

Environmental benefit is part of organic market value, but organic weed management usually means tillage, commonly considered a black mark for soil health. Is there a middle ground?

Hairy vetch may be the key to reducing tillage in organic farming, at least in the short term. Martin Entz, a professor and agriculture systems expert from the University of Manitoba has been looking at mulches for organic weed suppression, rather than the tillage typically used. “We found that when we used the right mulch,

Crop Diagnostic School offered a cutaway view of how crop roots move through soil

Along with her colleagues, Marla Riekman, land management specialist with Manitoba Agriculture, took up a shovel last month at Crop Diagnostic School to help show what’s going on underground with roots. Allan Dawson met up with Riekman to learn about the types of root systems in crops, how they extract nutrients from the soil, the effects of

Researchers at the University of Delaware found that when a plant has its leaf nicked, it sends out an alert to neighbouring plants, which begin beefing up their defences.

Injured plants can warn their neighbours

That smell of fresh-cut hay may be organic compounds 
from the damaged leaves

A high school student working on a research project at the University of Delaware has discovered that damaged plants can send a warning to their neighbours, which grow larger to compensate. Working in the lab on weekends and during summer breaks, Connor Sweeney cultured an estimated 1,000 arabidopsis plants — also known as mustard weed


To Clear-Cut Or Not, That Is The Question

Tree huggers think clear-cutting is a sin, but woodlot foresters say it’s sometimes the right thing to do. “There’s basically two stand types in southern Manitoba,” Carol Graham, a MAFRI woodlot forester based in Souris, said at a recent presentation at the Forester’s Memorial Hall in Baldur. “The one that’s most prevalent is an even-aged

Brandon Researchers On The Hunt For Root Rot Pathogens

Studies at the Brandon Research Centre have not yet turned up fusarium graminearum in root rot pathogens affecting local peas and dry beans. Last year, researchers began looking at the possibility that the fungus responsible for fusarium head blight in wheat could infect those crops after a recent report from North Dakota discovered that the


Increased Nodulation Can Equal More Soybean Yield

CHOOSE THE RIGHT INOCULANT FOR BEST PAYBACK The math is pretty simple: Increased nodulation equals more fixed nitrogen which can translate into more yield. For Manitoba soybean growers, the key is trusting the right inoculant to deliver the most bottom-line benefits. Most soybean growers in Manitoba use BioStacked inoculants. They perform better than single-action inoculants

Bugs Free For The Picking

“If you’ve ever seen fleas on a dog, how they jump and go crazy – that’s how these things move” – Nancy Gray, Iaps Co-Ordinator For Eastern Saskatchewan The best things in life are free, they say. That includes leafy spurge beetles. A bug net, a paper bag, a cooler and some ice packs are
