Waterlogged fields. Why?

Farmers have been putting the blame on unusually heavy rainfall and also the Environment Agency on TV news, but is that really the case? How about modern farming practice?  1) How many farmers clean their ditches annually? Not round our way!  2) Land drains used to be used but do not seem to be renewed or put in any more.  Those that still work have been there for a long while.   No drainage = waterlogging.  3)  Modern farming uses increasingly larger and heavier machinery which compacts the soil and so impedes water flow through it. 4)  To counteract compaction land is ploughed deeper and deeper by bigger ploughs (which need heavier machinery -  a vicious cycle).  This mixes subsoil clay with the surface loam and so reduces its ability to drain.  No wonder water lies on the surface, with large detriment to crop yields.  Water lies on the surface next to a clogged but empty ditch.  See what I mean?  More sustainable farming methods are needed, that are in tune with the environment and all it can (and will) throw at us.
