Well, If effort has any rewards you deserve them in Spades (pun unintended) It,s a credit to you that you have achieved all this by your own hard work.
If i understand you right you have dug a trench by your compost heap to help with the waterlogged ground, now after all your hard work i don,t want to put any more work on you
BUT if that trench was to be say 12 or 18 inches deep you could turn it into a French Drain/ Soak trench just by filling it with stones, maybe any stones you dig up in your beds could also go in there, it is better to use fairly big stones as this leaves bigger spaces between them for the water - half inch stones or bigger would do, if the trench is near a cultivated area or spills from the compost you could put a strip if mesh half way through the stones to stop clay being washed down and clogging up the soakage, if the trench was very difficult to dig because the ground is compacted you can drive the prongs of your digging fork into the bottom of the trench to help with soakaway. I,d do it for you but i,m in Ireland. Sounds a lot of work but it really is,nt that much.
Anyway, this may not be a priority for you at present.
All the very best,
Regards Hammer
