Agree with Monocock on the fertiliser - IIRC - I think I used some left over 20:10:10 as it was "free".
My strip is on top of high ground and when I acquired the land it had already been properly land drained with the old fashioned permeable clay pipes - so I don't really have a problem with wet patches. My pet hate is seing all the clover circles at 3" high whilst the grass having been cut a week earlier is a nominal but uniform 1 1/2"
I use an 8ton flat roll and in addition to spring rolling try to roll it perpendicular to the strip after I have harvested the crop on either side after a light rain or dew. I then roll it the long way, too. This minimises those little ruts caused primarily by the tractor or gang mower wheels.
Do be very careful about the seed bed preparation - a chum of mine locally has wasted a year and a few hundred quid on seed because the bed was poorly prepared, it is very rutted. Land my aeroplane on his strip? I wouldn't even take my tractor down it!
