Pay particular attention to #31....
31. Does anhydrous kill the earthworms in my soil?
Yes. When anhydrous ammonia is knifed into the soil, approximately 15% of the earthworm population is initially killed. Nevertheless, the anhydrous ammonia does increase the amount of available nutrients; as a result, earthworms will gradually move back into the application zone where they will multiply rapidly due to the fertile conditions. Consequently, 6-8 weeks after injection of anhydrous ammonia, the total number of earthworms is usually larger than what was originally present.
