So I logged on to my Google Reader today and found an interesting article on my National Geographic feed.

According to an article on the magazine's Web site, new research suggests using ash and pee -- or urine for those inclined toward prudishness :-) -- to make a gangbuster fertilizer team.

Here's what got my attention:

When it comes to cultivating a green thumb, gardeners perhaps need only look to their urinals and fireplaces.

That's because human urine mixed with wood ash can help produce bumper crops of tomatoes, new research shows.

Here's my favorite part, though:

Urine can be collected from eco-friendly, urine-diverting toilets. Or farmers could just collect their pee in cans.

Check out the article for more on the process, then gather the firewood. We're savin' those ashes this year. As for the pee, I don't think there's a need to hoard it, there should be plenty to go around when the time is right.
