It will be interesting to see how it does in sandy soil though. It's all had home made compost added and I've already sprinkled organic fertiliser around, but I'm going to try getting some down under a part of some of my rows of crops so I should then be able to see if there is a significant difference, even if just for water retention. Just need a nice non windy day to start riddling.

BYW if you google 'charcoal water retention' you get a lot of sites about bloated stomachs and ankles.
