Researchers hope to hone in on biological soil testing when it comes to inoculating legumes

Manitoba expat Barney Geddes, an assistant professor with the microbiological sciences program at North Dakota State University, likes to tell health care researchers how important the development of nitrogen fertilizer was. In terms of human lives saved, it’s had a greater impact than all innovations produced by medical science put together. “It’s sort of entertaining,”

Growers of soybeans and other pulse crops need to know both if nodules are present in acceptable number, and if they’re functioning properly.

Choosing the right inoculant strategy

After some disappointing results this season, one pulse crop specialist says it’s time to take a hard look at these practices

Manitoba Agriculture pulse crop specialist Dennis Lange says it’s a good time to think about just what’s the right approach regarding inoculants for pulses. “This year I’ve had a few calls on peas and soybeans from western Manitoba where they are finding very poor nodulation,” Lange told the Co-operator in a recent interview. He says

Farmers need to be aware of the vast world beneath their feet — healthy plants depend on it

It just might be that the most important living beings on any farm aren’t found in the barn — but in the soil. Bacteria, mycorrhiza, fungi, nematodes and even earthworms are key to understanding and promoting plant growth, University of Manitoba soil scientist Mario Tenuta told the Manitoba Forage Seed Association’s annual conference in Winnipeg


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

Boosting Legume Nitrogen Fix

McGill University, Montreal, Quebec, and Becker Underwood, Ames, Iowa, have signed a commercial licensing agreement granting Becker Underwood exclusive rights to patented nitrogen-fixing technology developed by a team of McGill researchers. Becker Underwood is a developer, marketer and producer of bioagronomic products for agriculture. Legumes such as soybeans, peanuts, peas, lentils and alfalfa form symbiotic

New twists on growing nitrogen, building soil organic matter

It is well known that alfalfa and other legumes in a crop rotation fix nitrogen from the atmosphere into the soil. What may be less widely understood, however, is the extra boost that more diverse crop rotations offer to long-term yields in the form of increased organic matter. This phenomenon is described by soil scientists
