When liquid injecting legume inoculants, can I tank mix trace elements or other fertilisers?

As a rule no, do not tank mix rhizobium as typically they’re very sensitive to a pH shift away from neutral and in some cases the element being used may be toxic to the inoculant. Copper and zinc are definitely harmful and other products have anecdotally been found to negatively affect nodulation outcomes. A not uncommon occurrence is where the user will note a significant drop in nodulation the longer the products were mixed together. The first few seeding runs were OK and the subsequent nodulation dropped for the latter part of the tank delivery. Situations will vary but there is definitely a high risk of damage or death of the Rhizobium if kept in suspension with trace elements and/or other liquid nutrients.
