Our supplier of worm castings is OMRI listed. By summer 2023, Urban Worm Company Worm Castings themselves will be OMRI-approved as our supplier is our sole source of worm castings. If you require an OMRI certificate, please e-mail us at firstname.lastname@example.org and we can discuss a direct purchase from our OMRI-listed castings supplier.
If stored in a sheltered or indoor location away from direct UV light, the worm castings will store well for 6 months or more. We have tested both fresh and 6-month old castings from the same batch and the tests were very similar to one another. We tended to see a decrease in nematodes but an increase in fungal biomass with our 6-month castings.
Please inquire about our capacity as it fluctuates by season. We are generally able to accommodate 2-5 truckload orders but for quantities beyond that, we will need to work with you to develop a shipping plan. We may also have similar, but not OMRI-approved sources of worm castings available for purchase if your needs outstrip our supply.
