According to the film 'The Fastest Indian,' pee is a great fertiliser for citrus trees. Bert Munroe said it, how can it be wrong!

One of our cats used to pee in a particular spot regularly. The result was a bare spot in the lawn, surrounded by lush, overfertilised grass. Very obvious.
So maybe you should pee in your plantation.....
Unless you don't want it to be obvious?
