The only uses for human urine that come to mind are as a
component of fertilizer (mostly for the urea nitrogen
content).  This cannot be done directly on growing crops
as it will burn foliage.  Instead, urine can be added to
composting organic matter to supply nitrogen to the
composting organisms which then fix part of the nitogen
in forms which are useful in gardening.  There may be a
small further use as an animal repellent to help prevent
deer and other pests from lunching in a garden area.
