I am going to plant edible soy beans, string beans and great northern field beans to harvest for a crop and till in for added nitrogen. I plan to inoculate the seed but I don't know which rhizobia I should use. Also, my wife would like to know how the inoculant will affect the fruit of the plant that we will be eating.
Many garden centers and Internet seed sources sell bean seed inoculants. Although some rhizobia are specific to particular kinds of leguminous plants, products sold as bean seed inoculants should be acceptable for use with all of the kinds of beans you plan to grow. To be sure, read the product label carefully.
The inoculant won't affect the fruit you will be eating. However, if the growing area lacks bean rhizobia, the crop may be larger and of higher quality if you add them.
