Demystifying biological inputs

A new partnership brings science-based field data to ag input listings to help growers sort fact from fiction

Biome Makers’ BeCrop Trials system measures changes in the soil microbiome after a product is applied. While the AgList/Biome Makers badge doesn’t validate efficacy, it signals a product has been through third-party field trials.

Interest in biological crop inputs continues to grow

Nutrien exec shares thoughts on uptake and profitability of biological crop inputs

It was only a few years ago that interest in alternative methods such as biologicals to boost a crop’s nutrient uptake seemed to spike in popularity. But according to Spencer Harris, senior vice-president of global ag retail for Nutrien Ag Solutions, biologicals are not all that new for Nutrien — the global ag retailer has been researching biological crop inputs for nearly two decades.

Plant-based plant protection

Crop chem firm Gowan Canada has picked up registration for its first biological product in the Canadian horticulture market. The product, called EcoSwing, is approved for control of mummy berry in high-bush blueberries and powdery mildew in cucurbits such as pumpkins, squash and cucumber. It’s also approved for suppression of apple scab in apples and […] Read more



Some biostimulant products are meant to help see crops through environmental stressors such as unusual cold or heat.

Biologicals aren’t the silver bullet

The products can be complements, not replacements, for other inputs

Glacier FarmMedia — Biological products have been touted as replacements for synthetic chemistry and fertilizer in crop production, but that may be a false promise. According to one pitch, if farmers add biological X to the soil, they can cut nitrogen rates by 15 pounds per acre. According to another, biological Y can control a […] Read more

Nitrogen-fixing biologicals fall short at field level

Challenges remain for products to achieve their hoped-for potential

Glacier FarmMedia — Dave Franzen is a straight shooter. If he doesn’t know the answer, the North Dakota State University soil scientist will admit it; if he does, he’ll tell you. As an example, in the summer of 2022 researchers from land grant universities across the north-central U.S. studied commercially available, biological nitrogen-fixing products to […] Read more

Adding biologicals to the soil doesn’t always work in the field, so a better approach could be altering the plant genome to work in synergy with soil microbes, a plant scientist and soil microbiology expert from the University of Kansas says.


Ways to improve the microbiome

Scientists consider how we could better support relationships between plants, soil and microbes

Glacier FarmMedia — The hyperbole around biologicals and what they can do for crop production sounds like 10 million crickets in a suburban backyard. There’s a lot of noise around biologicals, and for good reason. Soil contains millions of bacteria, fungi and other microbes that perform vital functions for plants. As a result, global agri-science […] Read more

Farmer interest growing in plant biostimulants

Companies hope to fill an existing 'knowledge gap' about the purpose of these products

Glacier FarmMedia — At 2 p.m. on July 17, Ryan Bonnett and many other people at the Ag In Motion farm show near Langham were seeking a place in the shade. The temperature was around 30 C and the word “hot” came up in most conversations at the show. The afternoon temperature was also on […] Read more

Photosensitizers are expected to help control "soft-bodied" insects such as aphids, Loveland's Francisco Manzano says.

Nutrien buys into biocontrol

How did the seller — oil company Suncor — wind up in crop pest control?

Glacier FarmMedia — Photodynamic inactivation is not a phrase used in everyday conversation, but it could become an effective control of insect and fungal pests in agriculture. “Photodynamic Inactivation (PDI) of micro-organisms using natural photosensitizers has shown itself to be a powerful tool to combat bacteria and fungi (in crops),” says a 2019 paper published […] Read more
