By using urine instead of chemical fertilizers you’re also doing a service to the environment and potentially protecting your health from any unwanted and unknown side effects of those chemicals. Aged Urine Makes Great Plant Fertilizer . Bacteria from urinary tract infections often harbor antibiotic resistance. New research from the University of Michigan found that recycled, aged human urine can be used as a fertilizer with low risk of transferring antibiotic-resistant DNA to the environment. urine must be mixed with carbon-rich materials in order for the nitrogen to become accessible to the plants.
