Microbial Biostimulants and Biofertilizers for Crop Production Database

Microbes and substances they produce affect crops profoundly. For some years, manufacturers and growers have attempted to capitalize on these effects in two broad ways. First, manufacturers look to identify microbes (or substances they produce) that may provide consistent benefits to growers. Manufacturers then work to offer formulations for delivering the beneficial microbes to crops. Second, growers purchase and use microbe-containing products.

More products become available and more growers use a wider array of them each year. Still, selecting a microbe-containing product can be very difficult, partly because product information is inconsistent, difficult to find, and difficult to apply effectively. Growers consistently report that greater access to credible, relevant, and easy to use information is essential to their using microbe-containing products more often and effectively.

Our *new database* of OMRI-listed companies manufacturing microbial biostimulant and biofertilizer products was created to help address this need. We hope it helps you select and use microbe-containing biostimulants and biofertilizers more confidently. View the database and download as a PDF or sortable excel file.
We created a separate HANDOUT of things to consider when selecting a microbial biostimulant product advertised to enhance crop growth. For those curious to know the types and names of organisms commonly found in microbial biostimulants, it contains the 76 distinct species of bacteria and 51 species of fungi we found in a review of 344 OMRI-listed products!
