Southeastern Alberta | Inoculants are probably the best insurance for making a decent crop. Even though the microbes are in the field after years of soybeans, what if heat, or cold, or drought, or water saturation has messed them up and reduced their populations? Also, it seems that there is always a new strain on the market so the more strains you can have in your soils means that you will have more chances that at least some will survive and thrive in the conditions your crop is facing at that moment in time.
Up here, where beans are new and there is no native rhizobium, we are being encouraged to double inoculate -using both a granular and liquid form from two different companies. | |
