What should I do if my inoculant has frozen in storage?
Inoculants contain living biological organisms. Consistent storage that keeps the organisms alive is vital for ensuring the survivability of the rhizobia and any additional biological contained. When inoculants freeze, this impacts the survivability of the rhizobia depending on the carrier and thus the efficacy of the product you are using to inoculate your pulse crop. If your granular inoculant freezes, it is not recommended to use it. Rather, ensure you replace it with new product that's been properly stored to ensure full survivability of the organisms and that you are inoculanting your pulse crop with the highest viable rhizobia organisms count possible.
Always read and follow label directions.
