Our team offers resources to help commercial vegetable growers, especially sustainable-organic, make the best use of MBBs. However, as a grower, MBB manufacturer or supplier, grower advisor, researcher, educator, agricultural journalist, or organizational representative, you can help. The shared goal is to improve the reliability with which MBBs are selected, used, and evaluated. Some approaches to meet this goal are listed below.
-
- Check out our database of OMRI-listed companies manufacturing microbial biostimulants and biofertilizers and submit feedback on improvements to the database. MBB manufacturers especially are encouraged to provide links to reports describing the performance of their products.
- Curious to know the types and names of organisms commonly found in microbial biostimulants? We reviewed ingredients of 344 OMRI-listed products and found 76 distinct species of bacteria and 51 species of fungi! Find these and other things to consider when selecting a microbial biostimulant in our handout about products advertised to enhance crop growth.
- Listen to and review summaries of microbial-based biostimulant call-in conversations hosted by the VPSL.
- View information about recent VPSL research projects using microbial biostimulants:
