According to
this article at Scientific American, tomato is a valid plant for human
urine fertilizer. I have a tomato producing very dark purple fruits, but none of them have ripened and I've been picking from other plants for six or eight weeks. So I decided that was a good candidate for special treatment. I aimed for near the base of the plant, but not on it, and spritzed some neighboring plants in the process. I'm sure this is unnecessary, but out of an abundance of caution, I gave the area a quick rinse. We got .68 inches of rain between 0700 (when I check the rain gauge each morning) yesterday and today, so I went with the easier undiluted option. I think you can tell that everything is wet from the rain even though you can't really see the soil where I was peeing.
I guess if some detail isn't quite right, I'll try again in an hour. :)
