I do not believe the inoculate could survive the rumen system. If the pasture already had clover growing in the past then there would likely be microbes present. But then some clovers take special inoculates. In a small pasture one could apply the inoculate to the individual plants. But in larger pastures the entire pasture would have to be treated. This defeats the purpose of mixing the seed with the feed in the first place. To check and see if the proper microbes are present, dig up some of the clover. It should have noduals that are pink in color.
