I believe the prevalence of Yew trees in churchyards is because these trees were popular amongst pre-Christian religious groups and the church colonised the pre-Christian 'holy' grounds and built their churches there.
Edd, I was always told by my seriously gardening family that the reason for putting a few crocks in a pot was to create an arch over the drainage holes so that they didn't get blocked by compost; therefore allowing good drainage. It also explains why old broken flowerpots (with a curve) are the best things to use.
With urine and composting I have been told on my compost course that it is a good compost accelorator, but should be diluted; human urine is pretty strong stuff.
