No one has disagreed with the fact that soil erosion can and does occur, although I am minded to point out that it is rare on allotments or domestic gardens in the UK, being more common here on inappropriately cultivated slopes and de-hedged mega-fields in commercial farming aka agri-business.
Neither has anyone deplored any wish to do what can be done to both raise awareness and to combat it both now and in the future. Indeed it is apparent that there are many techniques to combat it that can be applied on traditional, experimental and intensive agriculture, forestry and gardening, as well as on a domestic scale if people so wish.
To move on can we also agree that in a logical discussion definitive statements should be provable by reference to facts, whereas opinions do not need factual qualification when declared as such.
Therefore can we assume from here on that the four foot topsoil is unproven, but that erosion occurs under various circumstances and the thread is about ways to maintain or improve soil depth and growing quality relative to its current levels.
