Wood ash and urine fertilizer?

yummy yellow small onesBoing Boing has an interesting post on a National Geographic news article that reports on a recent round of tests to see how productive a mix of human urine and wood ash would be for tomatoes.

The plants fertilized this way yielded 4 times as much fruit as non fertilized plants, and bore a significant increase in the nutrient magnesium.

I would be a little concerned about the long term salt build up that may occur with this method and need more information before I try something as risky as mixing a salty substance with our topsoil.

how would it be different than peeing in straw, in terms of adding salts to the soil?

I'd say it'd be pretty much equivalent. Have you tried peeing on straw and had no problems with salts?

Ive peed in leaves, but not enough to make a significant impact. I'm interested to learn more about this

Me too! I'm going to keep my eyes peeled for some definitive information and will definitely report anything I find.
