New strain of rhizobia enters the soybean inoculant game

New strain of rhizobia enters the soybean inoculant game

Lallemand Plant Care recently discovered Bradyrhizobium elkanii

Until recently, Bradyrhizobium japonicum has been the primary nitrogen-fixing bacteria in commercial soybean inoculants, but Lallemand Plant Care recently discovered a new strain called Bradyrhizobium elkanii that it has incorporated into its new liquid inoculant product, LALFIX DUO SL PROYIELD. “In laboratory testing under artificial conditions, we found that Bradyrhizobium elkanii is about 50 per […] Read more

If you’re growing soybeans, you should have a plan to get them inoculated

Soybeans can biologically fix 50 to 60 per cent of their nitrogen, with the rest coming from soil reserves. Bradyrhizobium japonicum is a bacteria specific to soybeans that causes nodule development on plant roots, working symbiotically with the soybean plant to fix nitrogen. Because this rhizobium is not native to Canadian Prairie soils, soybean growers […] Read more


Why soybeans need inoculant and how some crops fix nitrogen without it

Why soybeans need inoculant and how some crops fix nitrogen without it

Plus, never do this with inoculant

Next to water, nitrogen is usually the most limiting nutrient in crop production. In prairie agriculture, by far the major source of fixed nitrogen for crop production is nitrogen produced industrially via the Haber process. But nitrogen fixation by legumes is also a very important economic factor in world agriculture. The nitrogen-fixing family of plants, […] Read more

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

BASF to boost inoculant production at Saskatoon

The Canadian crop protection arm of Germany’s BASF plans to step up its game in the crop inoculant business with a $10 million expansion at its Saskatoon plant. The facility, set up in 1988, handles production and research and development for BASF’s seed- and soil-applied rhizobium/bacillus inoculants, exported and sold worldwide under the Nodulator brand […] Read more

Crop Diagnostic School organizers seeded plots to demonstrate the impact of different treatment on plant growth. Plots were planted with or without inoculant, with or without nitrogen, and one plot had inoculant, nitrogen, and phosphorus. This photo of peas is with no inoculant, no nitrogen.

The basics of pulse nodulation

Nodulation 101: how pulse crops work with bacteria to fix their own nitrogen

At Saskatchewan Agriculture’s Crop Diagnostic School at Swift Current in July, a lot of the in-field real estate was devoted to plots of lentils and peas. Organizers had seeded plots of both crops with and without nitrogen, and with and without inoculant. These plots gave Garry Hnatowich, research director at Saskatchewan’s Irrigation Crop Diversification Corporation […] Read more


Nodules on a soybean plant.

Why nodulation fails

When nodules don’t form, yield will suffer. 
These recommendations could stop fixation failures

Nodulation failure can be disastrous to crop yields. In some cases, yield may be salvaged. In other cases, it will be too late. Two experts offer recommendations to avoid nitrogen fixation failures. Pre-farm failure Nitrogen fixation failures can occur at three points, says Garry Hnatowich, research director at the Irrigation Crop Diversification Corporation at Outlook, […] Read more
