Urea may have competition – Human urine
and has no comments yet.
Human urine is superior to urea, a common nitrogen-rich mineral fertiliser, according to the results of a study carried out in a farmer’s field outside Nepal's capital city.
Researchers who tested the effects of applying different combinations of urine, compost and urea on sweet pepper, Capsicum annuum, found that urine synergises best with compost. Urine for the study was sourced from mobile public toilets in the city and compost prepared from cattle manure.
