Can I Use Shade Leaves to Make a Liquid Fertiliser?

I wonder whether by pulping the leaves and adding them to water then letting them decompose a bit and then shaking them up into a 'green tonic' they could be added to the soil of a plant in order to fertilise it?
My logic is that since these leaves should contain all of the nutrients that a plant needs to make a leaf in the first place they should make an excellent nutrient source.
Could anyone with some experience in these matters please enlighten me as to their opinions?
Thanks
(and sorry for the name I really should (and will) rejoin with a different one! I just couldn't work out how to alter it in my personal page preferences since there doesn't seem to be an option.)

LOL I LOVE stoner logic =D + rep for the idea but I dont think there will be any nutritional value in your hasty made slurry of herbal goodness. Maybe use as an air freshener. If a plant is already in NEED of ferts, using the fert lacking plant mater isnt gonna help. It may sustain it for a while though. Like if a person drank their own pee, they may pull a little nutrition from it but its not better than real food/ nutes. Its like degrading every time you recycle. So the next fan leaves would have even less nutes for the next batch of feed. Etc and the cycle would continue. Thats just MY stoner logic.

Thanks for the reply quietguy420.
Though I would have thought the anology would be chomping down on a roast made from your own hand rather than drinking your own pee!
I had another couple of ideas that I'm also wondering about; if you watered a plant with carbonated water (non- sweetened or flavoured soda water, for example) would the roots absorb the CO2 and if you were doing a hydroponic (or one of its variants) type grow could you add carbonated water to the water they are growing in to aid in CO2 absorption? I read that the top 33 per cent of the roots are happy to be exposed to the air alone in an aeroponics setup so that's where my reasoning for this idea comes from. Any ideas?
I just had a look at your youtube video and "Nyum! Nyum!"
That 'land sativa', was it a Thai strain by any chance? I couldn't make out what you said. Thai is my all time favourite.

Ditto that.



Yeah, it wouldn't work like you think it would. It has to decompose quite a bit, before it'll become useable to plants, and wouldn't be practical. Plus, the nutes aren't in there anymore, not in nute form. They've been converted to plant matter/energy.
