Primo R1

It takes four to six pounds of Nitrogen to produce a bushel of soybeans. A variety of factors can lead to your soybeans not getting the Nitrogen they need to thrive, but with a soybean inoculant, your plants get the optimal Nitrogen levels to support greater yield potential.

Soybean inoculants contain strains of rhizobia bacteria that are specific to soybeans. When applied to the seed or soil, these bacteria colonize the root system and form nodules, where they convert atmospheric nitrogen into a form that the plant can use. This increases the availability of nitrogen to the plant, which can result in improved growth, yield, and quality.

Soybeans naturally get Nitrogen from:
• Organic sources
• Residual sources leftover from previous years
• Nitrogen-producing bacteria (rhizobia)

The latter is a symbiotic relationship between the soybean and rhizobia. The soybean produces nodules to house the rhizobia and provides carbohydrates that feed them. They then produce Nitrogen that feeds the soybeans.

How often you inoculate your soybeans will largely depend on the condition of your soil. Soybeans need Nitrogen to grow, and rhizobia is the best way to provide it. The number of background rhizobia in your soil can be weakened by flooding, extreme hot or cold weather conditions, and soil pH levels. So not only can the rhizobia in your soil be scarce, but you also might not have the right kind of rhizobia present to help with nodulation and Nitrogen production.

That’s why we recommend following a regular inoculant application when planting — to ensure that the right amount of the right rhizobia is there. An inoculant for soybeans helps rhizobia and soybeans work together to produce the Nitrogen soybeans need.

Fields vary year-round — high ground, low ground, high pH, low pH — so there’s no reliable way to know if the right bacteria is in the soil or if it’s in the right quantity. For less than a bushel per acre, however, you can ensure that you get the right type and amount of rhizobia to enable your soybeans to produce as many nodules as possible to generate the Nitrogen they need with Primo R1..

Not all rhizobia are the same. You may have some residual rhizobia in your field, but it could not be the best at producing the amount of Nitrogen required by soybeans to produce maximum yields. Using an inoculant for soybeans when you plant helps provide the best possible Nitrogen-produce rhizobia.

Yes. Primo R1 coupled with FlexConnect enhances operational efficiencies and agronomic benefits by providing consistent, high-quality soybean rhizobia inoculant on every seed across your field.

Yep. Soybean inoculant also helps produce efficiencies within the plant, like improving general appearance and health, better utilizing the Phosphorus and Potassium available to the plant, and fighting off stressors. When plants are properly nourished with the right nutrients, they’re more resilient to drought and other extreme weather conditions and produce an all-around better yield.

It’s proven that a soybean rhizobium inoculant increases soybean yield. Plenty of products say they’ll help produce higher yields, but the most overlooked strategy is a simple, biological inoculant like Primo R1. Primo R1 is a multi-strain Bradyrhizobium japonicum soybean inoculant. It includes more higher-powered rhizobia to out-compete background soil populations. That sounds complicated, but it’s really a quite simple, smart product. The point is, start simple and don’t underestimate how powerful a biological soybean inoculant can be.

Yes, soybean inoculants such as Primo R1 can be used in conjunction with other fertilizers and pesticides.
