Just about anyone will tell you that pee and food don’t mix. The idea of someone urinating on your food before it makes its way onto your plate is probably enough to make you feel a little nauseous – but, surprise! Piss can make veggies grow bigger and tastier, especially when mixed with wood ash.
It’s common knowledge that urine is good for compost – some gardeners even install toilet seats above their compost piles to make it easier for women to contribute. Now, a study has confirmed that human urine mixed with wood ash can produce as many high-quality tomatoes as synthetic fertilizers without risks to human health.
From Science Daily:
In the study, Surendra Pradhan and colleagues point out that urine, a good source of nitrogen, has been successfully used to fertilize cucumber, corn, cabbage, and other crops. Only a few studies, however, have investigated the use of wood ash, which is rich in minerals and also reduces the acidity of certain soils. Scientists have not reported on the combinaton of urine and wood ash, they say.
The new study found that plants fertilized with urine produced four times more tomatoes than nonfertilized plants and as much as plants given synthetic fertilizer. Urine plus wood ash produced almost as great a yield, with the added benefit of reducing the acidity of acid soils. “The results suggest that urine with or without wood ash can be used as a substitute for mineral fertilizer to increase the yields of tomato without posing any microbial or chemical risks,” the report says.
So, basically, if you want big tomatoes, just pee in your fireplace ashes and then spread them on the soil. Cheap, easy, and your drunken party guests will be more than happy to assist. Gotta love it!
