| In the right circumstances, you can pee on a straw-bale to eventually produce compost. Urine contains lots of nitrogen, straw contains lots of carbon, and so this is a perfect recipe for producing good compost. You can put the bale in any out-of-the-way place. It won’t smell because the bacteria will have a ‘balanced diet’ of carbon and nitrogen, and so won’t have to give off ammonia (a way of removing excess nitrogen). You could also collect urine in a container with a funnel, and tip it onto your compost heap when it’s full. This will benefit the heap, especially if it has a lot of carbon-rich material like dry leaves, twigs, straw or hay. | In the right circumstances, you can pee on a straw-bale to eventually produce compost.
