Fire Fighter's Foam/Bull's Blood
When I was a young J/T,at Kinloss in the 1970s,I remember one enlightening "fact" which came about from a tallish tale. Those of you familiar with the Moray area will, no doubt, have heard of the Findhorn Foundation whose early claim to fame was that they could grow very large cabbages in pi** poor soil.(sand basically) Google them if you haven't.
Anyway; the upshot, from gnarled old SACs and Corporals in crew room conversation, was that,in their day, many a squadron/unit,in desert locations,had grown large veggies by use of life-ex foaming agent that the Fire Sections were issued with. Apparently, in times gone by,this agent was made from real bull's blood and had a relatively short shelf life. Which probably meant there was lots of it and it was awkward to get rid of overseas. Somebody, somewhere discovered it's properties as a fertiliser, word spread and the speciality crop was carrot. (Do well in sandy soil and grow very well with good fertiliser)
Anyone out there like to confirm or quietly quash.
