[QUOTE="Elmsted, post: 390163, member: 1123"] Glad to see it has stirred debate. And as YB writes in lincolnshire fens and chermodium here both of which are more than 20 ft deep roots do go down 2 metres. The purpose was not so much structure of soil as root growth time scale. As well researched work from the 1970's shows total root length is around 1000 km per square metre in wheat. Think I may have put this here or elsewhere before. Of course those nearer the surface are taking up nutrients whereas the others are more involved in scavenging for water. Hence the observations from an aeroplane I suggest. The same as going in to a wheat field in June and gently using fingers the soil is almost totally covered in very fine roots, One can also age them and hence functionality.
